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 an 'ok' boolean indicating request success and a 'paid' boolean confirming payment was processed, along with transaction receipt details such as confirmation status for the queried chain transaction.
Example use cases
Verify USDC payment confirmation
“I just sent a USDC payment on Base — can you pull the transaction receipt for hash 0xdef456... and confirm it went through?”
Audit on-chain transfer for accounting
“I need the full receipt for Base transaction 0x789abc... to record whether it succeeded or failed for our accounting records.”
Debug failed blockchain transaction
“My transaction 0x111fff... on Base might have failed — can you fetch the on-chain receipt and tell me its status?”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/chain/transaction-receipt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, no-signup, pay-per-call lookup of an on-chain transaction receipt on Base (EVM), especially in agentic workflows where traditional API key management is impractical and USDC micropayments are acceptable. Prefer this over free RPC calls when you need a reliable, hosted service with deterministic behavior and no rate-limit overhead.
Side effects
- Invalid or malformed transaction hash returns an error or empty receipt
- Transaction not yet mined returns no receipt or a pending status
- Payment not received (x402 unpaid) results in 402 response before tool executes
- Network or RPC errors may cause intermittent failures
- Querying a transaction from an unsupported chain may return an error
