horizonpulse.dev/api/chain/head

Block height API: current block number, slot or ledger index for Base, Polygon, Ethereum, Solana and XRPL. Optional network (comma list; default all five). Per network: chainId, height, headTime, headAgeSeconds, finalizedHeight and finalityGap (EVM finalized tag, Solana finalized slot, XRPL validated ledger). Read-only queries to public network servers run by third parties. Billed when at least one network answers; bad input or every RPC down: not charged on Base (other rails may charge).
