GET /api/block Session or bearer

Server timestamp

/api/timestamp returns server Unix seconds, not chain time:

{"success":true,"errors":[],"data":{"unix_timestamp":1704067200}}

Use server time for the login proof. Its timestamp must be a canonical decimal string less than 600 seconds from the server in either direction. The full public-route allowlist is in the auth reference; public guild reads are not limited to /api/guild/this.

Indexed block and readiness

/api/block returns a current-block object or null with chain_id, height, tip_height, lag_blocks, status and updated_at. The response also carries meta from api_readiness([]) in the same SQL snapshot. A response can be HTTP 200 with success: true and still have data_ready: false or transaction_ready: false.

Read snapshot metadata for the exact contract. This route requests no specific projection model, so it cannot certify a different response’s inventory/work data. tip_height is observed indexer evidence, not a replacement for current native status, simulation or a committed transaction receipt.
