## 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-bazaar-rank-agent-focused-service-discovery-5693fe08
```

Example prompt: Show me the top x402 services being used by AI agents right now — ranked by paying wallets over the last 30 days, up to 100 results, tagged as agents.

## When to prefer this

Choose this endpoint when you need real-usage-backed discovery of x402 services specifically active in the AI agent ecosystem, rather than a static registry or self-reported listing. It is ideal when you need verifiable, auditable rankings (snapshot hash + scoring revision) and want to filter by actual 30-day payment activity rather than declared metadata alone.

## Known failure modes

- Payment not sent or incorrect USDC amount — returns 402 Payment Required
- Invalid or malformed query parameters — returns 400 with error detail
- No services match the requested tag or filter criteria — returns empty services array with count 0
- Snapshot index temporarily unavailable — returns 503 or stale data
- Rate limit exceeded — returns 429
