# `v5.db.transport.rest` API documentation
|
||
|
||
[`v5.db.transport.rest`](https://v5.db.transport.rest/) is a [REST API](https://restfulapi.net). Data is being returned as [JSON](https://www.json.org/).
|
||
|
||
You can just use the API without authentication. There's a [rate limit](https://apisyouwonthate.com/blog/what-is-api-rate-limiting-all-about) of 100 request/minute (burst 200 requests/minute) set up.

|
||
```
|
||
|
||
|
||
## `GET /journeys`
|
||
|
||
Uses [`hafasClient.journeys()`](https://github.com/public-transport/hafas-client/blob/5/docs/journeys.md) to **find journeys from A (`from`) to B (`to`)**.
|
||
|
||
`from` (A), `to` (B), and the optional `via` must each have one of these formats:
|
||
|
||
- as stop/station ID (e.g. `from=8010159` for *Halle (Saale) Hbf*)
|
||
- as a POI (e.g. `from.id=991561765&from.latitude=51.48364&from.longitude=11.98084` for *Halle+(Saale),+Stadtpark+Halle+(Grünanlagen)*)
|
||
- as an address (e.g. `from.latitude=51.25639&from.longitude=7.46685&from.address=Hansestadt+Breckerfeld,+Hansering+3` for *Hansestadt Breckerfeld, Hansering 3*)
|
||
|
||
### Pagination
|
||
|
||
Given a response, you can also fetch more journeys matching the same criteria. Instead of `from*`, `to*` & `departure`/`arrival`, pass `earlierRef` from the first response as `earlierThan` to get journeys "before", or `laterRef` as `laterThan` to get journeys "after".
|
||
|
||
Check the [`hafasClient.journeys()` docs](https://github.com/public-transport/hafas-client/blob/5/docs/journeys.md) for more details.

## `GET /stations`
|

If the `query` parameter is used, it will use [`db-stations-autocomplete`](https://npmjs.com/package/db-stations-autocomplete) to autocomplete *Deutsche Bahn*-operated stops/stations. Otherwise, it will filter the stops/stations in [`db-stations`](https://npmjs.com/package/db-stations).
|
||
|
||
Instead of receiving a JSON response, you can request [newline-delimited JSON](http://ndjson.org) by sending `Accept: application/x-ndjson`.
