# Cash Rate Target and realised overnight cash rate

`GET /api/v1/rba/cash-rate`

Reserve Bank of Australia policy rate path. Combines table F1 series for the Cash Rate Target (FIRMMCRTD), same-day change (FIRMMCCRT) and realised unsecured interbank overnight cash rate (FIRMMCRID) with the event-driven policy change log in table A2 (ARBAMPCCCR, ARBAMPCNCRT, ARBAMPCRPESB, ARBAMPNRPESB). History back to 1990 for the Cash Rate Target.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
