# Check claim indexing sync across all chains

`GET /v4/claims/health`

## Request

- Base URL: `https://api.merkl.xyz` (the document declares no server; this is the origin it was published from)
- URL: `https://api.merkl.xyz/v4/claims/health`
- Auth: `apiKey` (a scheme the document does not define)

Always returns HTTP 200. `status` is `STALE` when claim indexing has fallen behind: either the latest on-chain claim has sat unprocessed for at least 2 hours (or no processing checkpoint exists yet), or an indexing source is at least 2 hours behind the live chain head. `OK` otherwise. Aggregated over all chains; chains whose status can't be computed (e.g. RPC unreachable) are skipped. Configure a keyword monitor to alert when `STALE` is present.
