# Base Transaction Status Lookup

> Base Transaction Status Lookup is a paid API for AI agents from money-reactor.makar52nn2016.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Returns on-chain receipt details for a Base mainnet transaction hash: status, block number, gas used, from/to addresses, and log count

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-lookup-f16b416c
```

Example prompt: Can you check whether the Base transaction 0x4a3b2c1d... actually succeeded — I need to know the status, which block it landed in, and how much gas it used?

## When to prefer this

Use this endpoint when you need to verify the outcome of a specific Base mainnet transaction by hash — particularly for confirming payments, checking settlement status, or auditing counterparty claims. Prefer this over generic block explorers when you need a structured, machine-readable receipt in an automated agent workflow. Best suited for post-execution verification rather than real-time mempool monitoring.

## Known failure modes

- Invalid or malformed tx hash returns an error
- Transaction not yet indexed (very recent) may return pending or not-found
- Non-Base chain tx hashes will return not found or incorrect results
- Missing tx query parameter returns a bad request error
- RPC node downtime may cause transient failures

## How this service works

On-chain transaction receipt for any Base tx (?tx=0x...): status, block, gas used, from/to, logs count — agents verify their own settlements and counterparty claims

## Output

Returns a JSON object with the transaction status (success/failed/pending), block number, gas used, sender address (from), recipient address (to), and count of event logs emitted by the transaction.
