# Agent Data Tools: Base Transaction Lookup

> Agent Data Tools: Base Transaction Lookup is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-14).

Look up the details of a transaction on the Base blockchain by its hash, returning status, gas, addresses, and block metadata.

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 agent-data-tools-base-transaction-lookup-7087819b
```

Example prompt: Can you look up the Base transaction 0x7d108fa131ed949c76d50caf2e7dfe25fc9903b9d276c40a0446d8afbdfe86b0 and tell me whether it succeeded, how much gas it used, and which addresses were involved?

## When to prefer this

Use this endpoint when you need to verify or inspect a specific Base network transaction by its hash — particularly for confirming payment status, debugging smart contract calls, auditing gas costs, or checking block inclusion timing. It is pay-per-call with no API key required, making it ideal for agents that need occasional on-chain lookups without a persistent blockchain RPC subscription.

## Known failure modes

- Invalid or malformed transaction hash (not 0x + 64 hex chars) returns an error
- Transaction hash not found on Base returns a not-found error
- Network or RPC outage may result in a timeout or 5xx response
- Hash for a transaction on a different chain (e.g. Ethereum mainnet) will not be found

## How this service works

Read public static documentation as text or Markdown with code, tables, headings and links for $0.002 USDC on Base via x402. Inspect real cached examples and an unsigned quote, then buy with a capped Node CLI. No account or API key. No JavaScript rendering, authenticated or paywalled access. Other paid utilities remain available.

## Output

Returns a JSON object with the transaction hash, from and to addresses, chain identifier, nonce, status (success/failure), gas used, number of logs emitted, method ID called, ETH value transferred, block timestamp (ISO 8601), block number, gas price in Gwei, number of confirmations, any contract address created, and the execution fee in ETH.
