How this service works
Retrieve a real EVM transaction and normalized block, sender, recipient, nonce, value, gas, fee, type, and input fields by hash.
Output
A JSON object with a success boolean, the network name (e.g. 'base'), and a transaction object containing the hash, block_number, from address, to address, and value_wei. Additional fields may be present.
Example use cases
Verify incoming payment on Base
“Can you check transaction 0xabc123...def456 on Base and confirm who sent it, how much wei was transferred, and which block it landed in?”
Audit DeFi transaction on Ethereum
“I need to inspect Ethereum transaction 0x7f3e8a... — pull the from address, to address, and block number so I can cross-reference it with our records.”
Investigate suspicious Arbitrum transfer
“Look up transaction 0xdeadbeef...cafe on Arbitrum and tell me the sender, recipient, and value — I'm trying to trace where some funds went.”

Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/evm_transactionWhen to prefer
Choose this endpoint when you need a pay-per-use, no-subscription lookup of EVM transaction metadata across Base, Ethereum, or Arbitrum. It is well-suited for agents performing due-diligence, audit trails, or payment verification in agentic workflows that settle via x402/USDC, avoiding the need to manage your own blockchain RPC infrastructure.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on specified chain returns failure or empty result
- Unsupported chain identifier causes a bad request
- Network connectivity issues with the RPC node may cause timeouts
- Missing required transaction_hash query parameter returns a validation error
