**Category:** Travel | **Website:** [ratp.fr/](https://ratp.fr/) | **Docs:** [parse.bot/marketplace/b0532457-bbe2-41d7-8f34-8eec607c675c/ratp-fr-api](https://parse.bot/marketplace/b0532457-bbe2-41d7-8f34-8eec607c675c/ratp-fr-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/ratp/`
**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

### Get all traffic

Get an overview of traffic status for all RER lines (A through E) in Paris. Each line includes a name, a French-language summary of current conditions, and a numeric severity level where 0 means normal operation and higher values indicate increasing disruption severity.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/ratp/get-all-traffic \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get disruptions

Get detailed information about current and upcoming perturbations (disruptions) for all RER lines (A through E) in Paris. Returns only lines that have active disruptions or a non-normal status level. When no disruptions exist, returns a message field instead.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/ratp/get-disruptions \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get rer a traffic

Get real-time traffic status for RER A, including current status classification and detailed disruption information. Returns the line status (normal, planned_works, perturbed, critical), a French-language summary, and an array of active disruptions with type, location, and message. No input parameters required.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/ratp/get-rer-a-traffic \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
