# x402-audit Full Transaction Intel

> x402-audit Full Transaction Intel is a paid API for AI agents from x402-audit.tatschluizguilherme.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-30).

Returns complete transaction details for a given tx hash on Base, Optimism, or Ethereum Mainnet: raw tx data, receipt, decoded function call, event summary, gas costs, and confirmations in one call

## 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 x402-audit-full-transaction-intel-ec129633
```

Example prompt: Can you give me a full breakdown of what transaction 0x4a3b...c9f2 did on Base — what function was called, whether it succeeded, what events it emitted, and how much gas it cost?

## When to prefer this

Use this endpoint when you need a comprehensive, single-call view of exactly what a transaction did on Base, Optimism, or Ethereum Mainnet — combining raw tx data, receipt, decoded function call, and event summary that would otherwise require 3-4 separate RPC calls. Prefer this over raw eth_getTransactionByHash or eth_getTransactionReceipt when you need human-readable decoded calldata and event summaries without running a full indexer.

## Known failure modes

- Transaction hash not found on the specified chain — returns 404 or null result
- Wrong chain specified — tx exists on a different network, returns not found
- Transaction still pending — receipt not yet available
- Unrecognized 4-byte selector — function call returned as raw hex, not decoded
- Malformed transaction hash input — returns validation error
- Payment of 0.1 USDC not fulfilled — x402 payment required error
- RPC node timeout — upstream provider unavailable

## How this service works

Pay-per-call on-chain API for AI agents and developers: wallet audits, token safety audits (honeypot detection), live gas prices, token prices, transaction receipts, balances, ENS resolution, block data, ERC-20 allowances, transaction simulation, swap quotes and multicall batches — all computed on-chain via public RPCs (no external market API). Pay per request in USDC on Base via the x402 exact scheme (EIP-3009 transferWithAuthorization). No API key, no signup, no subscription.

## Output

A JSON object containing: raw transaction fields (from, to, value, nonce, type, maxFeePerGas, maxPriorityFeePerGas, input calldata), receipt fields (status success/reverted, gasUsed, effectiveGasPrice, logs), block timestamp and confirmation count, a decoded function call object with the 4-byte selector matched to a named function and typed arguments, and a structured event summary listing event types (Transfer, Approval, Swap, Deposit, etc.) with their decoded parameters.
