# Get delayed RBOB gasoline futures curve with exact decimal values

`GET /v1/futures/rbob`

## Request

- Base URL: `https://api.oilpriceapi.com`
- URL: `https://api.oilpriceapi.com/v1/futures/rbob`
- Auth: API key in header `Authorization`

Returns the dated RBOB futures curve with standard numeric fields and exact
decimal-token companion strings. Public quote rows are delayed by at least 10 minutes; daily
settlement, volume, and open interest are separate prior-session fields.
This additive route does not change the legacy single-price or other
futures responses. A separately labelled close is not currently available.

**Premium Feature** - Futures data access required.

- `500`: Unexpected server error. Retry transient failures with bounded backoff and retain the request ID when contacting support.
- `503`: Exact RBOB quotes are unavailable or an active contract quote exceeds the 96-hour maximum servable age. Quotes past the 30-minute collection limit are served with `metadata.stale` and `metadata.freshness_status` instead.
