How this service works
Retrieve a live EVM block header and a bounded list of real transaction hashes by height, tag, or block hash.
Output
Returns a JSON object containing success status, network name, and a block object with the block number (as a string), block hash (hex), total transaction count, a list of transaction hashes (up to the specified limit), and a flag indicating if the transaction list was truncated.
Example use cases
On-chain block confirmation check
“I need to verify that block 33752215 was mined on Base — can you pull its hash and transaction count?”
Real-time Ethereum block monitoring
“What is the current latest block on Ethereum? I need the block number, hash, and total transaction count.”
Arbitrum block transaction audit
“Fetch the block at height 150000000 on Arbitrum and return up to 100 transaction hashes so I can review what happened in that block.”

Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/evm_blockWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call EVM block metadata across Base, Ethereum, or Arbitrum without managing your own RPC node. It is ideal for agents performing on-chain verification, block confirmation checks, or transaction audits at low cost ($0.002 USDC per call) with no infrastructure setup required.
Side effects
- Invalid or non-existent block number returns an error or empty result
- Unsupported chain name returns a validation error
- Block hash not found on the specified chain returns failure
- Transaction limit out of range (>500) causes a parameter validation error
- Payment failure via x402 results in 402 response before data is returned
