**Category:** Travel | **Website:** [bahn.de/](https://bahn.de/) | **Docs:** [parse.bot/marketplace/c1cb2cfd-28fd-4f25-bef6-38583df6376a/bahn-de-api](https://parse.bot/marketplace/c1cb2cfd-28fd-4f25-bef6-38583df6376a/bahn-de-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/deutsche-bahn/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Autocomplete station

Search for train stations or locations by partial or full name. Returns matching stations with their IDs, coordinates, and available transport products (ICE, regional, S-Bahn, etc.). Results are ordered by relevance. Use the returned station name as input to search_connections.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `limit` | integer | No | Max number of results to return |
| `query` | string | Yes | Partial or full name of the station (e.g. 'Berlin', 'Hamburg Hbf') |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/deutsche-bahn/autocomplete-station \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"limit":"<integer>","query":"<string>"}'
```

### Search connections

Search for train connections between two stations on a given date and time. Returns available journeys with departure/arrival times, duration, number of transfers, pricing (when available), detailed leg information including intermediate stops, and per-connection fare levels (Super Sparpreis, Sparpreis, Flexpreis). Station names are resolved internally via autocomplete. Pricing and fares may be null for third-party operators (e.g. FlixTrain).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `class` | string | No | Travel class: '1' for first class, '2' for second class |
| `date` | string | Yes | Travel date in YYYY-MM-DD format |
| `destination` | string | Yes | Destination station name (e.g. 'Hamburg Hbf') |
| `origin` | string | Yes | Origin station name (e.g. 'Berlin Hbf') |
| `time` | string | Yes | Departure time in HH:MM format |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/deutsche-bahn/search-connections \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"class":"<string>","date":"<string>","destination":"<string>","origin":"<string>","time":"<string>"}'
```
