## 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 openwebninja-reverse-geocoding-api-c78b468d
```

Example prompt: What address and local business details are at the coordinates 40.6958453, -73.9799119 in the US? Return results in English.

## When to prefer this

Use this endpoint when you need to resolve raw GPS coordinates (latitude/longitude) into human-readable address or local business information, especially for US-based locations. Prefer this over forward geocoding when you already have coordinates and need place details.

## Known failure modes

- Missing required lat or lng parameters returns an error
- Invalid or out-of-range coordinates may return no results
- Unsupported region or language codes may cause fallback or error
- Payment not fulfilled (402) if x402 payment header is missing or insufficient
- Rate limits or service unavailability returning 5xx errors
