## 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 agoranome-buyer-wallet-overspend-audit-4a260be5
```

Example prompt: Can you run a spend audit on my x402 buyer wallet 0xAbc123... for the last 30 days and tell me if I overpaid for any API calls compared to their listed Bazaar prices?

## When to prefer this

Use this endpoint when an AI agent operator or the agent itself needs a structured financial audit of x402 API spending on Base — specifically to detect overpayments relative to Bazaar listed prices, catch oversize settlements, and identify payments to unlisted addresses. Prefer this over general blockchain explorers when you need x402-specific price comparison logic already built in.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Days parameter outside 1–30 range is rejected
- Wallet with no payment history returns empty/zero summary
- Bazaar price data unavailable for some payees may result in incomplete audit
- Network or blockchain RPC timeouts may cause partial results

## How this service works

Did my agent overpay for x402 APIs? The wallet overspend audit reads a buyer wallet's USDC payments on Base and checks each against the payee's listed Bazaar price: payments above the listed price, oversize settlements of 10x or more, and payments to addresses with no listing, totalled per seller. Use when an agent or its operator needs a spend audit of an x402 buyer wallet.

## Output

Returns a summary object with total payment count, total USD spent, total USD overpaid, and count of oversize payments (10x or more), plus a plain-English headline. Also includes a receipt with a receipt ID and impact pledge details.
