## 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 monitor-memoryapi-org-42694090
```

Example prompt: Pull the latest x402 API activity stats from memoryapi.org — I want to see which endpoints are getting the most paid calls, the usage trend data, and how many unique payers each one has.

## When to prefer this

Use this endpoint when you need real-time usage analytics specifically for x402-gated APIs hosted on memoryapi.org, including paid call rankings, payer diversity metrics, and trend data sourced directly from nginx logs. Prefer this over generic analytics tools when the focus is on x402 micropayment activity and endpoint monetization insights.

## Known failure modes

- No data available if nginx logs are empty or inaccessible
- Payment of $0.001 USDC required via x402 protocol — missing payment returns 402
- Stale data if log ingestion pipeline is delayed
- Rate limiting or infrastructure downtime returns 5xx error
