How this service works

Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).

Output

Returns a JSON object with the block number as a string, the transaction count (txCount) as an integer, and the block timestamp as a Unix epoch string for the requested Base blockchain block.

Example use cases

Audit block activity for DeFi event

“Fetch the block details for block 21000000 on Base so I can see how many transactions happened and when that block was mined.”

Correlate onchain timestamp with offchain event

“I need the timestamp for Base block 20500000 — I want to confirm exactly when that block was produced to match it against an offchain log.”

Monitor block transaction volume

“Look up block 21500000 on Base and tell me the transaction count so I can track how busy the network was at that point.”

When to prefer

Use this endpoint when you need fast, pay-per-call access to Base blockchain block metadata (block number, transaction count, timestamp) without setting up your own RPC node or managing API keys — especially in agent workflows that pay via USDC on Base using the x402 protocol.

Side effects

Invalid or non-existent block number returns an error or empty response
Block number too far in the future (not yet produced) returns not found
Malformed input type (wrong schema) returns a validation error
Payment failure via x402 protocol blocks the request before processing
