## How to call it through Zero

```sh
zero fetch --capability gadgethumans-reverse-geocode-api-faf6751d
```

Example prompt: What address or place name corresponds to latitude 37.7749 and longitude -122.4194?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call reverse geocoding solution with no API key setup and microtransaction pricing ($0.002 USDC per call). Ideal for agents that need occasional location lookups without committing to a subscription or managing API keys for dedicated geocoding services like Google Maps or Mapbox.

## Known failure modes

- Invalid or out-of-range latitude/longitude values (e.g. lat > 90 or lon > 180) may return an error or empty result
- Coordinates in remote areas with no known address may return sparse or null address fields
- Missing required lat or lon parameters will likely result in a 400 bad request
- Payment failure (insufficient USDC balance) returns a 402 Payment Required response
