## 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 srch-best-alerts-api-a5286996 -d '<json body>'
```

Example prompt: Can you pull structured earthquake alerts within 200 km of San Francisco (37.77, -122.41) from 2024-06-01 to 2024-06-30, minimum magnitude 3.5, and give me the top 20 results?

## When to prefer this

Choose this endpoint when you need structured, machine-readable earthquake or weather alert data tied to a specific geographic location or US state, especially in agentic workflows where you pay only per query via x402. It is well-suited for agents that need to programmatically assess risk, trigger notifications, or enrich location data with hazard information, without the overhead of scraping government alert feeds directly.

## Known failure modes

- Invalid or missing 'type' field (must be 'earthquake' or 'weather') — returns validation error
- Coordinates out of valid range — returns schema validation error
- Date format not matching ISO date (YYYY-MM-DD) — returns parse error
- Missing required 'area' field for weather queries — returns bad request
- Magnitude out of allowed range (-2 to 10) — returns validation error
- Payment failure via x402 protocol — returns 402 Payment Required
- No alerts found for the given parameters — returns empty result set
- Limit exceeding maximum of 100 — returns validation error

## How this service works

Structured alerts data for agents, paid per request with x402 v2

## Output

A structured JSON object containing a list of alert records matching the query. For earthquakes: event time, location, depth, magnitude, and geographic coordinates. For weather: active warnings, watch/advisory details, and affected area information. Results are capped at the requested limit (max 100).
