## 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 polyform-geo-location-brief-a324668a
```

Example prompt: Give me a quick location brief for the coordinates 36.1627° N, 86.7816° W — I want the place name, county, current temperature, and whether there are any active weather alerts.

## When to prefer this

Choose this endpoint when you need a fast, concise location snapshot — city name, county, temperature, and alert count — for a US coordinate without needing a full forecast or detailed weather breakdown. Ideal for enriching records, providing quick situational context, or routing decisions where a brief is sufficient.

## Known failure modes

- Coordinates outside the US may return no result or an error
- Missing or malformed coordinate input returns a validation error
- Upstream NOAA or geocoding service outage may cause degraded or failed responses
- Payment not received or insufficient USDC balance returns a 402 Payment Required error

## How this service works

Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.

## Output

Returns a JSON object with the resolved location name (city, state), county, current temperature in Fahrenheit, and the count of active weather alerts at that coordinate.
