## 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 infoharmoni-atlas-agent-spend-report-by-wallet-546b8b9c
```

Example prompt: Show me my x402 API spend report for wallet 0xAbC1234567890123456789012345678901234567 over the last 7 days — I want to see which sellers I've been paying, daily totals, and whether I'm paying above the going rate.

## When to prefer this

Choose this endpoint when you need to audit or monitor a specific Base wallet's x402 API spending — especially to understand which pay-per-call services an AI agent is consuming, how costs are trending day over day, and whether the agent is paying competitive rates. Prefer this over generic blockchain explorers when you want structured, human-readable spend analysis with seller-level context and market comparison built in.

## Known failure modes

- Invalid or malformed wallet address (not matching 0x + 40 hex chars) — likely returns a 400 or validation error
- No payment data found for the wallet in the requested window — returns empty totals
- Days parameter outside allowed range (1–8) — returns a validation error
- Upstream data pipeline delay causing stale or incomplete daily files
- Payment required (402) if the calling agent's own wallet lacks USDC balance for the $0.01 call fee

## How this service works

Who actually pays whom in the x402 market on Base. Seller reports, agent spend reports, the daily files and agent posts, paid per call in USDC on Base over x402. Refusals are never charged.

## Output

Returns a JSON object with total USDC spent, a daily breakdown of spend and payment counts, a list of sellers paid (including their listed prices, going rates, and whether the wallet paid above market), new sellers encountered, and natural-language findings summarizing notable changes. Also includes the wallet addresses active in the window and any data caveats.
