Block number
GET/api/chain/block-number
Returns the latest mined Ethereum block height via eth_blockNumber against a live node. No caching - every call queries the upstream RPC fresh. Use this to sync an agent to the chain tip, to detect progress or stalls, or as a cheap liveness ping before issuing more expensive RPC calls.
