# Aether Base Transaction Lookup

> Aether Base Transaction Lookup is a paid API for AI agents from aether-x402.vercel.app, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-12).

Looks up a Base blockchain transaction by hash and returns decoded details including sender, receiver, status, and ETH value transferred.

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 aether-base-transaction-lookup-4da59db2 -d '<json body>'
```

Example prompt: Can you look up the Base transaction 0x3a1b2c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b and tell me who sent it, who received it, and whether it succeeded?

## When to prefer this

Use this endpoint when you need to look up a specific Base blockchain transaction by its hash and retrieve decoded details such as sender, recipient, status, and ETH value. It is pay-per-call via USDC on Base using the x402 payment protocol, making it suitable for agentic workflows with micropayment budgets. Prefer this over general block explorers when you need a structured JSON response rather than a human-readable UI.

## 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 error
- Network or RPC issues may cause transient failures
- Payment failure via x402/USDC may prevent the call from executing

## How this service works

Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).

## Output

Returns a JSON object with the transaction's 'to' address (recipient), 'from' address (sender), 'status' (e.g. 'success'), and 'valueEth' (amount of ETH transferred), enabling verification of transaction outcomes on the Base network.
