How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
Returns normalized on-chain transaction data including transaction hash, block number, sender and recipient addresses, value transferred, gas used, gas price, transaction status (success/failure/pending), and timestamp — sourced from public blockchain RPC nodes with multi-source fallback and edge caching.
Example use cases
Verify crypto payment receipt
“I need to confirm that a USDC payment was actually settled on-chain — can you pull up the transaction details for hash 0x4f2a... and tell me if it succeeded, who sent it, and how much was transferred?”
Audit DeFi trade execution
“Can you look up on-chain transaction 0x9d3c... for me? I want to see the block it landed in, the gas used, and the recipient address so I can reconcile it with our trade records.”
Debug failed blockchain transaction
“A transaction I submitted seems to have failed — the hash is 0x7e1b.... Can you fetch the on-chain details and tell me its status, the sender, and what gas was actually consumed?”

Endpoint
GEThttps://x402.santyvv.com/api/chain/transaction?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, pay-per-use on-chain transaction lookup without setting up an account or API key — ideal for agents making occasional blockchain queries or prototyping. Prefer over Etherscan/Alchemy direct APIs when you want zero-setup USDC micropayment billing and normalized response format across multiple chains.
Side effects
- Transaction hash not found or not yet indexed — returns 404 or empty result
- Invalid or malformed transaction hash — returns 400 bad request
- Network congestion causing slow RPC response — may time out
- Payment failure via x402 if USDC balance insufficient — request blocked before execution
- Chain not supported — endpoint may return error if hash belongs to unsupported network
