# Health of every chain, one generic row each

`GET /health/chains`

## Request

- Base URL: `https://api.getchord.xyz/v1`
- URL: `https://api.getchord.xyz/v1/health/chains`
- Auth: none declared

What the status page is built from, readable directly. `quotes.engine` is the routing engine's own state (`ok`, `starting` after a deploy, `stale` when its pool sync stopped, `down`); `quotes.canary` is the small quote the status probe sends. `data.ageSec` is how old the newest indexed trade is and `data.maxAgeSec` the age past which the chain's data counts as delayed. `quotes` is null where Chord does not route (Solana), `data` is null where no tape runs. Answers from a 15-second memo.
