Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability spyfu-1cd2ee9b
```

Example prompt: Can you pull up my SpyFu API usage stats for October 2024 so I can see how many calls my account made that month?

## When to prefer this

Use this endpoint when you need to audit or report on the volume of SpyFu API calls made during a specific calendar month — particularly useful for billing reconciliation, rate-limit monitoring, or usage trend analysis. Prefer this over real-time usage dashboards when you need historical month-level granularity programmatically.

## Known failure modes

- Invalid or malformed usageDate format returns a 400 or error response
- Month with no usage data may return empty or zero counts
- Authentication failure if x402 payment or credentials are missing
- Future dates or dates before account creation may return empty results
- Network or gateway timeout from the paysponge.com proxy layer
