# Index freshness and depth

`GET https://api.getchord.xyz/v1/arc/status`

Source: https://getchord.xyz/docs/api-reference/operations/arcstatus/

Is the Arc rollup fresh, how far back it reaches, and the state of the pool index and the holder ledger. Check this before trusting a quiet number.

Served from Chord's rollup and index tables (every swap on Arc summed by hour, token and venue), never from a raw scan — so calls are cheap and every answer carries its coverage. No key needed. `503 NOT_READY` until the rollup has run on the deployment.

## Response 200

- **503**: The lane behind this endpoint is not ready or not enabled here (`NOT_READY`, `CHAIN_NOT_ENABLED`, `NOT_ENABLED`, `*_UNAVAILABLE`). Retry later; do not treat it as an empty answer.
