Technical details

Endpoint

GEThttps://x402.chainquery.com/v1/rpc/getbestblockhash?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a trustless, independently-operated Bitcoin full node's view of the current chain tip hash without setting up API keys. Ideal for agents that need to verify or anchor blockchain state, monitor for new blocks, or bootstrap further block-level queries. Prefer over block explorers when you want raw Bitcoin Core RPC semantics and pay-per-use pricing with no subscription.

Side effects

Payment failure (x402 payment not accepted) — returns 402 Payment Required
Node temporarily unavailable — returns 5xx error
Invalid query params JSON — returns 400 Bad Request
Network timeout if full node is syncing
