How this service works
Pay-per-call EVM utility API for AI agents and automation.
Output
A JSON object containing the transaction status (success/failure), network name, gas used, block number, contract address (if applicable), and the transaction hash. This gives the agent full confirmation of transaction finality and execution details.
Example use cases
Confirm DeFi swap settled on-chain
“I just submitted a swap on Base with tx hash 0xabc123...def456 — can you check the receipt and tell me if it went through and what block it landed in?”
Verify NFT mint transaction on Ethereum
“My NFT mint transaction on Ethereum has hash 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b — did it succeed and what gas did it use?”
Audit deployed contract address on Polygon
“We deployed a smart contract on Polygon and the tx hash is 0xdeadbeef...cafe1234 — can you fetch the receipt so I can confirm the contract address that was created?”
Technical details
Endpoint
GEThttps://built-with-productos-voo8.vercel.app/v1/tx-receiptWhen to prefer
Use this endpoint when an AI agent needs to confirm the outcome of an EVM transaction — particularly on Base, Ethereum, Arbitrum, or Polygon — and requires structured receipt data (gas, block, status, contract address) programmatically. Prefer this over block explorer scraping or raw RPC calls when you need a pay-per-call, agent-friendly API with multi-network support in a single interface.
Side effects
- Invalid or malformed tx_hash (not matching 0x + 64 hex chars) returns a validation error
- Transaction not found on the specified network returns a not-found error
- Unsupported network value returns an enum validation error
- RPC backend temporarily unavailable may return a 5xx error
- Payment failure (insufficient USDC balance) returns 402 Payment Required
