# Base Transaction Status Checker

> Base Transaction Status Checker is a paid API for AI agents from 89-116-220-218.sslip.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns normalized transaction status (success, failed, or pending) with block info, confirmations, gas details, from/to addresses, and log count for a given Base mainnet transaction hash.

## Facts

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_JWSJ941UEkMptotdX8UdX

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 base-transaction-status-checker-967c864c
```

Example prompt: Can you check whether my Base transaction 0x3a1b2c4d5e6f7890abcdef1234567890abcdef1234567890abcdef1234567890ab went through — I want to know the status, how many confirmations it has, and how much gas was used?

## When to prefer this

Choose this endpoint when you need a single, normalized answer about a Base mainnet transaction's finality and details without stitching together multiple eth_getTransactionReceipt and eth_getBlockByNumber calls yourself. Ideal for payment confirmation flows, post-send verification, or agent pipelines that need to know how settled a transaction is before proceeding. Prefer over raw RPC calls when you want confirmations pre-computed and gas metrics normalized in one response.

## Known failure modes

- Invalid or malformed hash format (not 0x + 64 hex chars) returns validation error
- Transaction hash not found on Base mainnet returns not-found or null status
- Pending transaction may return status 'pending' with no block/confirmation data
- Network or RPC node connectivity issues may return a 5xx error
- Hash from a different chain (Ethereum mainnet, Optimism, etc.) will not be found

## How this service works

Base mainnet transaction status: success, failed or pending, with block, confirmations, gas used, effective gas price, from/to and log count. Use it after sending or receiving a payment to confirm it landed and how deep it is. One normalized JSON answer instead of combining receipt and block calls and computing confirmations yourself. Query: ?hash=0x...

## Output

A single normalized JSON object containing: transaction status (success, failed, or pending), block number, number of confirmations since inclusion, gas used, effective gas price, from and to addresses, and the count of event logs emitted — all derived from combining the transaction receipt and block data so the caller doesn't have to make multiple RPC calls.
