# GET /v4/claims/health

_Merkl API_

> Check claim indexing sync across all chains

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.
