# Transaction Status

> Transaction Status is a paid API for AI agents from www.x402financialdata.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns the success/failure status and contract execution error detail for an Ethereum transaction hash, catching reverted contract calls that bare confirmation checks miss.

## Facts

- Endpoint: GET https://www.x402financialdata.com/transaction-status/:tx_hash
- Price: $0.01/call
- Payment: x402
- Status: unknown

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-status-ec90dc96
```

Example prompt: Can you check whether Ethereum transaction 0x4dfa7b1be6578326be24ad2d330e7baf23230e18c2d2c67d8f41798e0e764b0b actually succeeded — including whether the contract call reverted even if the transaction was confirmed?

## When to prefer this

Use this endpoint when you need to distinguish between a transaction being mined and a contract call actually succeeding — critical for DeFi interactions, NFT mints, and any smart contract invocation where a revert would leave the transaction confirmed but the intended action unfulfilled. Prefer this over a bare block confirmation check whenever contract execution correctness matters.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Ethereum mainnet
- Only 'eth' chain is supported; other chains return unsupported chain error
- Network or Etherscan API downtime may cause lookup failures
- Very recent transactions not yet indexed may return not-found

## How this service works

Success/failure status for an Ethereum transaction hash in one call: post-Byzantium receipt status plus contract execution error detail, from Etherscan's V2 API -- catches the 'transaction confirmed but the contract call actually reverted' case a bare confirmation check misses. $0.01/call.

## Output

Returns the post-Byzantium receipt status (success or failure) for the transaction plus contract-level execution error detail — specifically surfacing cases where the transaction was confirmed on-chain but the underlying smart contract call reverted, along with the revert reason if available.
