# Chain totals

`GET /arc/overview`

## Request

- Base URL: `https://api.getchord.xyz/v1`
- URL: `https://api.getchord.xyz/v1/arc/overview`
- Auth: none declared

Last 24 hours (volume, swaps, tokens), venue share, 24 hourly buckets and up to 30 daily rows. The numbers on Chord's landing page come from this call.

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.

## Other responses

- `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.
