# Base Transaction Status Lookup

> Base Transaction Status Lookup is a paid API for AI agents from base-reads-api.rafliyaputra.deno.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-11-01).

Retrieves the confirmed status, block, gas usage, and confirmation count for a given Base blockchain transaction hash.

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-a27c2831
```

Example prompt: Can you check the status of my Base transaction 0x89c91c789e57059b17285e7ba1716a1f5ff4c5dace0ea5a5135f26158d0421b9 — I need to know if it succeeded and how many confirmations it has?

## When to prefer this

Use this endpoint when you need deterministic, pay-per-call lookups of Base transaction status without running your own node. Ideal for agents that need to verify on-chain settlements, confirm payments, or debug transactions on the Base L2 network. Prefer this over general-purpose Ethereum RPC endpoints when scoped specifically to Base and when cost-per-call billing is acceptable.

## Known failure modes

- Invalid or malformed transaction hash (not matching 0x + 64 hex chars) returns a validation error
- Transaction hash not found on Base returns a not-found or empty response
- Network or RPC node issues may return a temporary service error
- Payment failure via x402 if USDC balance is insufficient or wallet not configured

## How this service works

Pay-per-call read API for Base over x402 v2. Deterministic data, no advice.

## Output

Returns a JSON object with the transaction hash, from/to addresses, status (e.g. 'success' or 'failed'), block number, chain identifier ('base'), number of logs emitted, gas used, effective gas price in wei, and number of confirmations.
