## 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 saylor-innovations-data-desk-san-francisco-311-cases-c4c3a2ee
```

Example prompt: Pull the 20 most recent SF 311 graffiti cases from the last 14 days — I want to see the status, responsible agency, neighborhood, and location for each.

## When to prefer this

Choose this endpoint when you need real-time, filterable access to San Francisco 311 case data — especially when you want to combine recent individual case records with aggregate top-service statistics in a single call. Prefer it over raw SF open data portals when you want a clean, pre-filtered JSON response ready for agent consumption without parsing raw CSVs or managing pagination.

## Known failure modes

- Invalid days value (outside 1-60 range) may return an error or default behavior
- No matching cases for a very specific service keyword returns an empty recent array
- Service may return stale data if upstream SF 311 feed is delayed
- Limit values outside 1-50 may be clamped or rejected
- Network or payment (x402) failure prevents response entirely
