 ## Adding integration/end-to-end tests

-Refer to the [testing docs](docs/tests.md).
+The [end-to-end/system tests](https://en.wikipedia.org/wiki/System_testing) in [`test/e2e`](test/e2e), executing via `npm run test-e2e`, are querying real HAFAS endpoints, expecting valid & *reasonable* responses.
+
+The [integration tests](https://en.wikipedia.org/wiki/Integration_testing) (`npm run test-integration`) are the same `test/e2e` tests, running against *mocked* HAFAS responses from [`test/e2e/fixtures`](test/e2e/fixtures).
+
+1. Add a new end-to-end test that tests your feature/bugfix.
+2. Make sure the test passes. You can run your test exclusively using `test.only`.
+3. Record the HAFAS responses as [fixtures](https://en.wikipedia.org/wiki/Test_fixture) using `npm run test-integration:record`.
+4. Make sure the passes against *only* mocked responses using `npm run test-integration`.

-The maximum supported duration depends on the profile (see main readme), e.g. 720 for `db` and 60 for `dbnav`. In order to use the `dbris` profile, you need to pass the env vars `DB_API_KEY` and `DB_CLIENT_ID`.
-If you pass an object `opt.products`, its fields will partially override the default products defined in the profile.

+If you pass an object `opt.products`, its fields will partially override the default products defined in the profile. An example with the [BVG profile](../p/bvg):

 ## Response

 *Note:* As stated in the [*Friendly Public Transport Format* v2 draft spec](https://github.com/public-transport/friendly-public-transport-format/blob/3bd36faa721e85d9f5ca58fb0f38cdbedb87bbca/spec/readme.md), the `when` field includes the current delay. The `delay` field, if present, expresses how much the former differs from the schedule.

-You may pass a departure's `tripId` into [`trip(id, lineName, [opt])`](trip.md) to get details on the whole trip. For the `dbnav`/`dbweb` profile HAFAS trip ids will be returned, for the `db` profile, RIS trip ids will be returned, then the `trip()` endpoint supports both id types.
+You may pass a departure's `tripId` into [`trip(id, lineName, [opt])`](trip.md) to get details on the whole trip.

-For `db` profile, cancelled trips will not be contained in the response! For the `db` and `dbnav` profile, only the most important remarks will be contained in the boards.
+As an example, we're going to use the [VBB profile](../p/vbb):

 ```js
-import {createClient} from 'db-vendo-client'
-import {profile as dbnavProfile} from 'db-vendo-client/p/dbnav/index.js'
+import {createClient} from 'hafas-client'
+import {profile as vbbProfile} from 'hafas-client/p/vbb/index.js'

 const userAgent = 'link-to-your-project-or-email' // adapt this to your project!
-const client = createClient(dbnavProfile, userAgent)
+const client = createClient(vbbProfile, userAgent)

 // S Charlottenburg
 const {
 	departures,
 	realtimeDataUpdatedAt,
-} = await client.departures('8089165', {duration: 3})
+} = await client.departures('900000024101', {duration: 3})
 ```

-`realtimeDataUpdatedAt` is currently not set in db-vendo-client, because the upstream APIs don't provide it.
+`realtimeDataUpdatedAt` is a UNIX timestamp reflecting the latest moment when (at least some) of the response's realtime data have been updated.

 `departures` may look like this:

-# Dumps from DB Navigator API app.vendo.noncd.db.de
-
-In this directory, some intercepted traffic from DB Navigator. (Repo license does not apply to this directory.)
-
-You can browse some responses of the bahn.de API and others in the [fixtures](https://github.com/public-transport/db-vendo-client/tree/main/test/fixtures) and [e2e fixtures](https://github.com/public-transport/db-vendo-client/tree/main/test/e2e/fixtures).
-
-How to intercept DB Navigator traffic:
-
-1. Download/extract Split APK
-2. Merge APK (e.g. using [APKEditor](https://github.com/REAndroid/APKEditor))
-3. decompile using apktool
-4. edit [res/xml/network_security_config.xml](https://developer.android.com/privacy-and-security/security-config) to allow user CAs not just in debug 
-5. recompile using apktool, sign
-6. install on an Android
-7. intercept with a mitm decryption tool of your choice by installing CA cert into Android store (e.g. [PCAPdroid](https://github.com/emanuele-f/PCAPdroid) with [mitm addon](https://github.com/emanuele-f/PCAPdroid-mitm), no root needed)

+# HAFAS `mgate.exe` protocol
+
+The protocol of `mgate.exe` HAFAS endpoints is not openly (and freely) documented. The following documentation is based on general observations and reverse-engineering.
+
+*Note:* There are also `rest.exe` (a.k.a. "open API", a.k.a. "REST API") endpoints. This documentation is *not* about them.
+
+## date & time format
+
+Dates are encoded as `YYYYMMDD`, time strings as `HHMMSS`. These are in the timezone configured on the HAFAS/server side, *per endpoint*.
+
+Whenever HAFAS returns a time string that exceeds the day the response describes, it will add a "day offset". As an example, when you query departures at `2019-12-12T23:50+01:00` for the next 30 minutes, it will encode the departure at `2019-12-13T00:13+01:00` as `20191212` & `01001300`.
+
+For working code, check out [`parseDateTime()`](../parse/date-time.js).
+
+## coordinate format
+
+All endpoints I've seen so far use [WGS84](http://wiki.gis.com/wiki/index.php/WGS84). Values are multiplied by `10^6` though, so you would encode `{latitude: 1.23, longitude: -2.34}` as `{Y: 1230000: X: -2340000}`. There's an optional parameter `z` with the elevation.
+
+For working code, check out [`formatAddress()`](../format/address.js).
+
+## querying the API
+
+In many aspects, the API looks and feels like [RPCs](https://en.wikipedia.org/wiki/Remote_procedure_call). You must send queries via HTTP `POST`, with the minimal JSON body looking like this:
+
+```js
+{
+	"auth": {
+		"type": "AID",
+		"aid": "…" // endpoint-specific authentication token, e.g. `1Rxs112shyHLatUX4fofnmdxK`
+	},
+	"ver": "…", // endpoint-specific string, e.g. `1.15`
+	"ext": "…", // endpoint-specific string, e.g. `BVG.1`
+	"client": {
+		"type": "IPA", // might also be `IPH` for "iPhone" or `WEB` for "web client"
+		"id": "…", // endpoint-specific string, e.g. `BVG`
+		"name": "…", // endpoint-specific string, e.g. `FahrInfo`
+		"v": "…" // endpoint-specific string, e.g. `4070700`
+	},
+	"lang": "…", // language, sometimes 2-digit (e.g. `de`), sometimes 3-digit (e.g. `deu`)
+	"svcReqL": [
+		{
+			"meth": "…", // name of the API call, supported values depend on the endpoint
+			"req": {
+				// actual request parameters…
+			}
+			// some endpoints also require this:
+			"cfg": {
+				"cfgGrpL": [],
+				"cfgHash": "…" // endpoint-specific string
+			}
+		}
+	]
+}
+```
+
+- The data in `client` must be correct, otherwise HAFAS will reject your request.
+- HAFAS will return slightly different response formats (and slightly different levels of detail) for different `ver`, `ext` and `client.v` values.
+- All endpoints known support JSON & UTF-8, so make sure to send `Accept: application/json` & `Accept-Charset: utf-8` headers.
+- Most endpoints support at least GZIP compression, so make sure to send a `Accept-Encoding: gzip` header.
+
+For working code, check out [`request()`](lib/request.js).
+
+## Authentication
+
+There are three known types of authentication used among `mgate.exe` endpoints.
+
+For working code, check out [`hafas-client`'s `request()`](lib/request.js), [`public-transport-enabler`'s Java implementation](https://github.com/schildbach/public-transport-enabler/blob/69614c87af627e2feafc576882f2ccccdbf4b7e6/src/de/schildbach/pte/AbstractHafasClientInterfaceProvider.java#L845-L860), [`TripKit`'s Swift implementation](https://github.com/alexander-albers/tripkit/blob/724b6cd8c258c9c61e7443c81e914618b79393cb/TripKit/AbstractHafasClientInterfaceProvider.swift#L1473-L1495) or [`marudor.de`'s TypeScript implementation](https://github.com/marudor/BahnhofsAbfahrten/blob/cf64d53c6902981ec529d3952253b2c83bff9221/src/server/HAFAS/profiles.ts#L30-L54).
+
+### unprotected endpoints
+
+You can just query these, as long as you send a formally correct request.
+
+### endpoints using the `checksum` query parameter
+
+`checksum` is a [message authentication code](https://en.wikipedia.org/wiki/Message_authentication_code): You can compute it by [hashing](https://en.wikipedia.org/wiki/Hash_function) the request body and a secret *salt*.
+
+This secret can be read from the config file inside the accompanying client app. There is no guide for this yet, so please [open an issue](https://github.com/public-transport/hafas-client/issues/new).
+
+### endpoints using the `mic` & `mac` query parameters
+
+`mic` is a [message integrity code](https://en.wikipedia.org/wiki/Message_authentication_code), the [hash](https://en.wikipedia.org/wiki/Hash_function) of the request body.
+
+`mac` is a [message authentication code](https://en.wikipedia.org/wiki/Message_authentication_code), the hash of `mic` and a secret *salt*.
+
+This secret can be read from the config file inside the accompanying client app. There is no guide for this yet, so please [open an issue](https://github.com/public-transport/hafas-client/issues/new).
+
+## API responses
+
+A minimal valid response looks like this:
+
+```js
+{
+	"ver": "…", // endpoint-specific string, e.g. `1.15`
+	"lang": "…", // language
+	"ext": "…", // endpoint-specific string, e.g. `BVG.1`
+	"id": "…", // unique ID for each response?
+	"svcResL": [
+		{
+			"meth": "StationBoard",
+			"err": "OK",
+			"res": {
+				// result of the API call
+			}
+		}
+	]
+}
+```
+
+For working code, check out [`request()`](lib/request.js).
+
+### parse error
+
+todo: generic server error
+
+```js
+{
+	"ver": "…", // endpoint-specific string, e.g. `1.15`
+	"lang": "…", // language, sometimes 2-digit (e.g. `de`), sometimes 3-digit (e.g. `deu`)
+	"err": "PARSE", // error code
+	"errTxt": "…", // error message, not always present
+	"svcResL": []
+}
+```
+
+### authentication error
+
+```js

+	"lang": "…", // language
+	"ext": "…", // endpoint-specific string, e.g. `BVG.1`
+	"err": "AUTH", // error code
+	"errTxt": "…", // error message, not always present
+	"svcResL": []
+}
+```
+
+### API-call-specific error
+
+```js
+{
+	"ver": "…", // endpoint-specific string, e.g. `1.15`
+	"lang": "…", // language
+	"ext": "…", // endpoint-specific string, e.g. `BVG.1`
+	"svcResL": [
+		{
+			"meth": "StationBoard",
+			"err": "…", // error code, e.g. `H9300`
+			"errTxt": "…", // error message, e.g. `Unknown arrival station`
+			"res": {}
+		}
+	]
+}
+```

 If a journey leg has been cancelled, a `cancelled: true` will be added. Also, `departure`/`departureDelay`/`departurePlatform` and `arrival`/`arrivalDelay`/`arrivalPlatform` will be `null`.

 To get more journeys earlier/later than the current set of results, pass `earlierRef`/`laterRef` into `opt.earlierThan`/`opt.laterThan`. For example, query *later* journeys as follows:
@ -306,16 +339,19 @@ departure of last journey 2017-12-17T19:07:00+01:00

 ```

-## Using the `loyaltyCard` option
+If you pass `polylines: true`, each journey leg will have a `polyline` field. Refer to [the section in the `trip()` docs](trip.md#polyline-option) for details.
+
+If you pass `scheduledDays: true`, each journey will have a `scheduledDays` object looking like this:

 ```js
-import {data as loyaltyCards} from 'db-vendo-client/format/loyalty-cards.js' // see there for a list
-
-hafas.journeys(from, to, {

+}
 ```
-
-## The `routingMode` option
-
-The `routingMode` option is not supported by db-vendo-client. The behavior will be the same as the [`HYBRID` mode of hafas-client](https://github.com/public-transport/hafas-client/blob/main/p/db/readme.md#using-the-routingmode-option), i.e. cancelled trains/infeasible journeys will also be contained for informational purpose.

-# automated tests in `db-vendo-client`
-
-Because transit data is inherently dynamic (e.g. a different set of departures being returned for a stop now than in 10 minutes), and because it is of paramount importance that `db-vendo-client` actually works with HAFAS endpoints *as they currently work*, its testing setup is a bit unusual.
-
-`db-vendo-client` has three kinds of automated tests:
- unit tests, which test individual aspects of the case base in isolation (e.g. the parsing of HAFAS-formatted dates & times) – run via `npm run test-unit`
- end-to-end (E2E) tests, which run actual HTTP requests against their respective profile's HAFAS endpoint – run via `npm run test-e2e`
- integration tests, which are the E2E tests running against pre-recorded (and checked-in) HTTP request fixtures – run via `npm run test-integration`
-
-Because the E2E & integration tests are based on the same code, when changing this code, you should also update the integration test fixtures accordingly.
-
-*Note:* In order to be as reproducible as possible, the tests query transit data for a certain *fixed* point in time on the future, hard-coded in each profile's test suite (a.k.a. each file `test/e2e/*.js`). In combination with the recording & mocking of HTTP requests, this effectively makes the integration tests deterministic.
-
-## adding integration test fixtures
-
-As an example, let's assume that we have added an entirely new test to [the *DB* profile's E2E tests](../test/e2e/db.js).
-
-The behaviour of the HTTP request recording (into fixtures) and mocking (using the recorded fixtures) is controlled via an environment variable `$VCR_MODE`:
- By running the test(s) with `VCR_MODE=record`, we can record the HTTP requests being made. The tests will run just like without `$VCR_MODE`, except that they will query data for date+time specified in `T_MOCK` (e.g. [here](https://github.com/public-transport/db-vendo-client/blob/8ff945c07515155380de0acb33584e474d6d547c/test/e2e/db.js#L33)).
- Then, by running the test(s) with `VCR_MODE=playback`, because their HTTP requests match the pre-recorded fixtures, they work on the corresponding mocked HTTP responses.
-
-Usually, you would not want to update all *already existing* recorded HTTP request fixtures of the test suite you have made changes in, as they are unrelated to the test you have added. To only record your *added* test, temporarily change `tap.test(…)` to read `tap.only(…)`, and run with `TAP_ONLY=1 VCR_MODE=record`; This will skip all unrelated tests entirely.
-
-Then, check the augmented fixtures (in `test/e2e/fixtures`) into Git, and revert the `tap.only(…)` change. To make sure that everything works, run the entire test suite/file (*without `TAP_ONLY=1`*) with `VCR_MODE=playback`.

-*Note:* It might be that the test suite/file you want to augment hasn't been updated in a while, so that `T_MOCK` is in the past. In this case, recording additional fixtures from actual HTTP requests of your added test is usually not possible because the HAFAS API is unable to serve old transit data. In this case, you will first have to change `T_MOCK` to a future date+time (a weekday as "normal" as possible) and re-record all tests' HTTP requests; Don't hesitate to get in touch with me if you have trouble with this.

+# Writing a profile
+
+**Per HAFAS endpoint, `hafas-client` has an endpoint-specific customisation called *profile*.** A profile may, for example, do the following:
+
+- handle the additional requirements of the endpoint (e.g. authentication),
+- extract additional information from the data provided by the endpoint,
+- guard against triggering bugs of certain endpoints (e.g. time limits).
+
+This guide is about writing such a profile. If you just want to use an already supported endpoint, refer to the [main readme](../readme.md) instead.
+
+*Note*: **If you get stuck, ask for help by [creating an issue](https://github.com/public-transport/hafas-client/issues/new)**; We're happy to help you expand the scope of this library!
+
+## 0. How do the profiles work?
+
+A profile may consist of three things:
+
+- **mandatory details about the HAFAS endpoint**
+	- `endpoint`: The protocol, host and path of the endpoint.
+	- `locale`: The [BCP 47](https://en.wikipedia.org/wiki/IETF_language_tag) [locale](https://en.wikipedia.org/wiki/Locale_(computer_software)) of your endpoint (or the area that your endpoint covers).
+	- `timezone`: An [IANA-time-zone](https://www.iana.org/time-zones)-compatible [timezone](https://en.wikipedia.org/wiki/Time_zone) of your endpoint.
+- **flags indicating which features are supported by the endpoint** – e.g. `trip`
+- **methods overriding the [default profile](../lib/default-profile.js)**
+
+Let's use a fictional endpoint for [Austria](https://en.wikipedia.org/wiki/Austria) as an example:
+
+```js
+const myProfile = {
+	endpoint: 'https://example.org/bin/mgate.exe',
+	locale: 'de-AT',
+	timezone: 'Europe/Vienna'
+}
+```
+
+Assuming their HAFAS endpoint returns all line names prefixed with `foo `, we can adapt our profile to clean them:
+
+```js
+// get the default line parser
+import {parseLine} from 'hafas-client/parse/line.js'
+
+// wrapper function with additional logic
+const parseLineWithoutFoo = (ctx, rawLine) => {
+	const line = parseLine(ctx, rawLine)
+	line.name = line.name.replace(/foo /g, '')
+	return line
+}
+
+myProfile.parseLine = parseLineWithoutFoo
+```
+
+If you pass this profile into `hafas-client`, the `parseLine` method will override [the default one](../parse/line.js).
+
+You can also use the `parseHook` helper to reduce boilerplate:
+
+```js
+import {parseHook} from 'hafas-client/lib/profile-hooks.js'
+
+const removeFoo = (ctx, rawLine) => ({
+	...ctx.parsed,
+	name: line.name.replace(/foo /g, '')
+})
+
+myProfile.parseLine = parseHook(parseLine, removeFoo)
+```
+
+## 1. Setup
+
+*Note*: There are many ways to find the required values. This way is rather easy and works with most endpoints by now.
+
+1. **Find the journey planning webapp** corresponding to the API endpoint; Usually, you can find it on the public transport provider's website.
+2. **Open your [browser's devtools](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/What_are_browser_developer_tools)**, switch to the "Network" tab, and **inspect the requests to the HAFAS API**.
+
+If you can't find the webapp or your public transport provider doesn't have one, you can inspect their mobile app's traffic instead:
+
+1. Get an iOS or Android device and **download the "official" app.**
+2. **Configure a [man-in-the-middle HTTP proxy](https://docs.mitmproxy.org/stable/concepts-howmitmproxyworks/)** like [mitmproxy](https://mitmproxy.org).
+	- Configure your device to trust the self-signed SSL certificate, [as outlined in the mitmproxy docs](https://docs.mitmproxy.org/stable/concepts-certificates/).
+	- *Note*: This method does not work if the app uses [public key pinning](https://en.wikipedia.org/wiki/HTTP_Public_Key_Pinning). In this case (the app won't be able to query data), please [create an issue](https://github.com/public-transport/hafas-client/issues/new), so we can discuss other techniques.
+3. **Record requests of the app.**
+	- [There's a video showing this step](https://stuff.jannisr.de/how-to-record-hafas-requests.mp4).
+	- Make sure to cover all relevant sections of the app, e.g. "journeys", "departures", "live map". Better record more than less!
+	- To help others in the future, post the requests (in their entirety!) on GitHub, e.g. in as format like [this](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886). This will also let us help you if you have any questions.
+
+## 2. Basic profile
+
+*Note:* You should have read the [general documentation on `mgate.exe` APIs](hafas-mgate-api.md) to make sense of the terminology used below.
+
+You may want to start with the [profile boilerplate](profile-boilerplate.js).
+
+- **Identify the `endpoint`.** The protocol, host and path of the endpoint, *but not* the query string.
+	- *Note*: **`hafas-client` for now only supports the interface providing JSON** (generated from XML), which is being used by the corresponding iOS/Android apps. It supports neither the JSONP, nor the XML, nor the HTML interface. If the endpoint does not end in `mgate.exe`, it mostly likely won't work.
+- **Identify the `locale`.** Basically guess work; Use the date & time formats as an indicator.
+- **Identify the `timezone`.** This may be tricky, a for example [Deutsche Bahn](https://en.wikipedia.org/wiki/Deutsche_Bahn) returns departures for Moscow as `+01:00` instead of `+03:00`.
+- **Copy the authentication** and other meta fields, namely `ver`, `ext`, `client` and `lang`.
+	- You can find these fields in the root of each request JSON. Check [a VBB request](https://gist.github.com/derhuerst/ea5d6482b61aeb7384a2c788f43dc11d#file-0-serverinfo-http-L11-L33) and [the corresponding VBB profile](https://github.com/public-transport/hafas-client/blob/2baf2f6f0444ffc67317f8bafe0fe05f687e5fae/p/vbb/base.json#L2-L11) for an example.
+	- Add a function `transformReqBody(ctx, body)` to your profile, which adds the fields to `body`. todo: adapt this
+	- Some profiles have a `checksum` parameter (like [here](https://gist.github.com/derhuerst/2a735268bd82a0a6779633f15dceba33#file-journey-details-1-http-L1)) or two `mic` & `mac` parameters (like [here](https://gist.github.com/derhuerst/5fa86ed5aec63645e5ae37e23e555886#file-1-http-L1)). If you see one of them in your requests, jump to the [*Authentication* section of the `mgate.exe` docs](hafas-mgate-api.md#authentication). Unfortunately, this is necessary to get the profile working.
+
+## 3. Products
+
+In `hafas-client`, there's a distinction between the `mode` and the `product` fields:
+
+- The `mode` field describes the mode of transport in general. [Standardised by the *Friendly Public Transport Format*](https://github.com/public-transport/friendly-public-transport-format/blob/3bd36faa721e85d9f5ca58fb0f38cdbedb87bbca/spec/readme.md#modes), it is on purpose limited to a very small number of possible values, e.g. `train` or `bus`.
+- The value for `product` relates to how a means of transport "works" *in local context*. Example: Even though [*S-Bahn*](https://en.wikipedia.org/wiki/Berlin_S-Bahn) and [*U-Bahn*](https://en.wikipedia.org/wiki/Berlin_U-Bahn) in Berlin are both `train`s, they have different operators, service patterns, stations and look different. Therefore, they are two distinct `product`s `subway` and `suburban`.
+
+**Specify `product`s that appear in the app** you recorded requests of. For a fictional transit network, this may look like this:
+
+```js
+const products = [
+	{
+		id: 'commuterTrain',
+		mode: 'train',
+		bitmasks: [16],
+		name: 'ACME Commuter Rail',
+		short: 'CR',
+		default: true
+	},
+	{
+		id: 'metro',
+		mode: 'train',
+		bitmasks: [8],
+		name: 'Foo Bar Metro',
+		short: 'M',
+		default: true
+	}
+]
+```
+
+Let's break this down:
+
+- `id`: A sensible, [camelCased](https://en.wikipedia.org/wiki/Camel_case#Variations_and_synonyms), alphanumeric identifier. Use it for the key in the `products` array as well.
+- `mode`: A [valid *Friendly Public Transport Format* mode](https://github.com/public-transport/friendly-public-transport-format/blob/3bd36faa721e85d9f5ca58fb0f38cdbedb87bbca/spec/readme.md#modes).
+- `bitmasks`: HAFAS endpoints work with a [bitmask](https://en.wikipedia.org/wiki/Mask_(computing)#Arguments_to_functions) that toggles the individual products. It should be an array of values that toggle the appropriate bit(s) in the bitmask (see below).
+- `name`: A short, but distinct name for the means of transport, *just precise enough in local context*, and in the local language. In Berlin, `S-Bahn-Schnellzug` would be too much, because everyone knows what `S-Bahn` means.
+- `short`: The shortest possible symbol that identifies the product.
+- `default`: Should the product be used for queries (e.g. journeys) by default?
+
+If you want, you can now **verify that the profile works**; We've prepared [a script](https://runkit.com/derhuerst/hafas-client-profile-example/0.2.1) for that. Alternatively, [submit a Pull Request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) and we will help you out with testing and improvements.
+
+### Finding the right values for the `bitmasks` field
+
+As shown in [the video](https://stuff.jannisr.de/how-to-record-hafas-requests.mp4), search for a journey and toggle off one product at a time, recording the requests. After extracting the products bitmask ([example](https://gist.github.com/derhuerst/193ef489f8aa50c2343f8bf1f2a22069#file-via-http-L34)) you will end up with values looking like these:
+
+```
+toggles                     value  binary  subtraction     bit(s)
+all products                31     11111   31 - 0
+all but ACME Commuter Rail  15     01111   31 - 2^4        2^4
+all but Foo Bar Metro       23     10111   31 - 2^3        2^3
+all but product E           25     11001   31 - 2^2 - 2^1  2^2, 2^1
+all but product F           30     11110   31 - 2^0        2^0
+```
+
+## 4. Additional info
+
+We consider these improvements to be *optional*:
+- **Check if the endpoint supports the `trip()` call.**
+	- In the app, check if you can re-fetch details for the status of a single journey leg. It should load realtime delays and the current progress.
+	- If this feature is supported, add `trip: true` to the profile.
+- **Check if the endpoint supports the live map call.** Does the app have a "live map" showing all vehicles within an area? If so, add `radar: true` to the profile.
+-  **Consider transforming station & line names** into the formats that's most suitable for *local users*. This is just an optimal optimisation that makes it easier for users of the profile to use the data. Some examples:
+	- `M13 (Tram)` -> `M13`. With Berlin context, it is obvious that `M13` is a tram.
+	- `Berlin Jungfernheide Bhf` -> `Berlin Jungfernheide`. With local context, it's obvious that *Jungfernheide* is a train station.
+- **Check if the endpoint has non-obvious limitations** and let use know about these. Examples:
+	- Some endpoints have a time limit, after which they won't return more departures, but silently discard them.
