Endpoint
GEThttps://api.x402node.dev/chain/blockWhen to prefer
Use this endpoint when you need on-chain block-level metadata (timestamp, gas stats, base fee, tx count) for any of the five supported EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon) — either the latest block or a historically specific one. Prefer this over a full block explorer when you only need summary block data without full transaction details.
Side effects
- Unsupported chain specified — returns error indicating valid chain options
- Block number does not exist yet — returns error for future or out-of-range block
- Payment not included or insufficient — 402 Payment Required response
- Network/RPC timeout fetching block data — 5xx error
- Invalid block number format — 400 Bad Request
