How this service works
Global current weather, hourly forecasts, foreign-exchange rates, EVM reads, and deterministic utilities for AI agents. Pay per call with MPP or x402; no API key.
Output
Returns a JSON object with the transaction status (success/failure), the EVM network, gas used as an integer, block number, the original transaction hash, and the contract address (null if no contract was deployed in the transaction).
Example use cases
Confirm DeFi swap finality
“I just submitted a swap on Arbitrum — can you check transaction 0xabc1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcd and confirm it went through and tell me the block it landed in?”
Verify smart contract deployment
“Did our contract deploy successfully? Look up transaction 0xdeadbeef1234567890abcdef1234567890abcdef1234567890abcdef1234567890 on Ethereum and let me know if there's a contract address in the receipt.”
Audit gas costs on Polygon
“Can you fetch the receipt for transaction 0x9999aaaa1234567890abcdef1234567890abcdef1234567890abcdef1234567890 on Polygon and tell me the gas used so I can log it for our accounting?”
Technical details
Endpoint
GEThttps://built-with-productos-xszv.vercel.app/v1/tx-receipt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call lookup of a transaction receipt on Ethereum, Base, Arbitrum, or Polygon without managing API keys or subscriptions. It is ideal for AI agents that need to verify transaction finality, check gas costs, or confirm contract deployment on a one-off or low-frequency basis, especially within workflows already using x402 or MPP micropayments.
Side effects
- Invalid or malformed tx_hash (not matching 0x + 64 hex chars) returns an error
- Transaction hash not found on the specified network returns not-found error
- Unsupported network value (outside ethereum/base/arbitrum/polygon enum) returns validation error
- Payment failure via x402/MPP results in 402 Payment Required response
- Network RPC unavailability may cause timeout or 503 error
