# Transaction Receipt

> Transaction Receipt is a paid API for AI agents from bess-x402.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Fetches the mined EVM transaction receipt including success/revert status, gas used, effective gas price, fees (including L2 L1 fee), contract creation address, and decoded event logs (Transfer and Approval).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability transaction-receipt-3bcfb30b
```

Example prompt: Did my USDC transfer go through? Check the receipt for transaction hash 0xabc123...def456 on Base — I need to know if it succeeded, how much gas was used, and if there are any Transfer events.

## When to prefer this

Use this endpoint when you need to confirm the outcome of a specific EVM transaction — whether it succeeded or reverted, how much gas was consumed, what fees were paid (including L1 fees on L2 chains), and what on-chain events were emitted. It is ideal for confirming payments, token transfers, swaps, or contract deployments by hash. Prefer this over block explorers when you need structured, machine-readable output with decoded Transfer and Approval events ready for downstream processing.

## Known failure modes

- Transaction hash not yet mined — receipt not available (transaction still pending)
- Invalid or malformed transaction hash format
- Unsupported chain name provided
- Transaction hash does not exist on the specified chain
- Network or RPC timeout causing unavailable receipt data

## How this service works

Receipt of a mined EVM transaction: success or revert, gas used, effective gas price, fee (and L2 L1 fee), created contract and event logs with Transfer and Approval decoded. Use to confirm a payment or swap.

## Output

Returns a structured receipt object containing: transaction success or revert status, gas used, effective gas price, total fee paid (plus L1 fee for L2 chains like Base/Optimism/Arbitrum), the address of any newly created contract, and a list of event logs with Transfer and Approval events decoded into human-readable form.
