## 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 agentsmap-x402-seller-intelligence-510c2880
```

Example prompt: Before I pay for api.example.com, can you check its real payment history on AgentsMap — how many unique payers it's had in the last 7 days, what prices have been observed, and whether it's still healthy?

## When to prefer this

Use this endpoint when an AI agent or human needs to vet an x402 API before paying for it — checking whether it has real historical usage, consistent pricing, and a healthy status. Prefer this over raw on-chain lookups when you need aggregated multi-window metrics (24h/7d/30d), price change detection, and daily history in a single call. It is specifically designed for the x402 protocol ecosystem on Base and is the right choice when you have either a seller host domain or a payTo wallet address.

## Known failure modes

- Host or payTo not indexed — returns empty or null activity data if the seller has never been crawled
- Invalid payTo address format — rejected by schema validation (must match 0x hex pattern)
- Neither host nor payTo provided — endpoint may return an error or empty result
- New/inactive seller — zero payment activity returned, not an error but may look like failure
- Service temporarily unavailable — HTTP 5xx from upstream

## How this service works

AgentsMap tracks live x402 and ACP activity across Base and Solana with an indexable public surface plus a live map, discovery explorer, and charts.

## Output

Returns a structured object containing: real payment activity metrics (24h, 7d, 30d windows) including payment count, unique payers, and USDC volume; first and last payment timestamps; observed prices from 402 challenges; current endpoint health status; any detected price or payTo address changes; and daily historical payment data for trend analysis.
