How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with block details including block hash, parent hash, timestamp, miner/validator, transaction list, gas used, and other EVM block metadata for the requested block number.
Example use cases
Verify transaction inclusion in block
“I need to check what transactions were included in block number 18900000 — can you pull the full block data for me?”
Audit block timestamp for compliance
“What was the exact timestamp of block 20000000 on Base? I need it for a compliance audit.”
Monitor specific block for on-chain event
“Pull up block 19750000 for me and show me its hash and the number of transactions it contained.”

Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/chain/block-by-number?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, pay-per-call blockchain block lookups by number with no API key or signup required. Ideal for AI agents operating autonomously with a USDC wallet on Base, especially when fetching specific historical or recent blocks from EVM-compatible chains without maintaining a subscription.
Side effects
- Block number not found or not yet mined — returns error or empty result
- Invalid or missing block number parameter — returns validation error
- Chain not supported or schema parameter invalid — returns bad request
- x402 payment failure — returns HTTP 402 if payment is missing or insufficient
- Network or upstream RPC timeout — returns 5xx error
