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

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/12go-asia/`
**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.

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

## Endpoints

### Search trains

Search train routes between two stations on a given date. Returns all available trains with departure/arrival times, operator and train number, prices per cabin class, seat availability, and a booking link. Results are a single-page list of all trains for that date.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `date` | string | Yes | Travel date in ISO format YYYY-MM-DD. |
| `destination` | string | Yes | Destination station or city slug as used in the 12go.asia URL path (e.g. 'samarkand', 'chiang-mai', 'ho-chi-minh'). |
| `origin` | string | Yes | Origin station or city slug as used in the 12go.asia URL path (e.g. 'tashkent-central', 'bangkok', 'hanoi'). |
