# AgentAudit — What are AI agents buying? x402 commerce intelligence.

Pay per query with x402 ($0.01-$0.05, no signup), or subscribe on AWS Marketplace and pay on your AWS bill. You are charged only for successful (2xx) answers.

Coverage: every wallet that a CDP Bazaar (agentic.market) listing names as its Base USDC payTo, refreshed daily, indexed from 2026-05-12. A settlement is a USDC transferWithAuthorization (EIP-3009) into such a wallet, matched to the payer's AuthorizationUsed log in the same transaction. Plain USDC transfers are excluded. Solana is not indexed. Totals are aggregates: AgentAudit does not store individual settlements beyond the latest 50 (/v1/flow).

## Quick Start
```
GET https://agentaudit.waltsoft.net/v1/trending?period=all
Header: PAYMENT-SIGNATURE: <base64 x402 payment proof>
```

## What You Get
Trending x402 services, seller and buyer profiles, the latest settlements, and verified receipts for Base transaction hashes. Waltsoft's own test wallets are flagged (operator_wallet), so its self-payments can be told apart from real buyers.

## How to Pay (x402 Protocol)
1. Call the endpoint without payment and receive a 402 with payment requirements
2. Sign a USDC payment for the advertised amount (Base or Solana)
3. Send it base64-encoded in the PAYMENT-SIGNATURE (or X-PAYMENT) header
4. Retry and get your data
