## 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 geo402-reverse-geocode-505e9da9
```

Example prompt: What address or place name is at coordinates 48.8584° N, 2.2945° E? Just give me the street address, city, and country.

## When to prefer this

Choose this endpoint when you need on-demand reverse geocoding without a subscription or API key, and you can pay per call via x402 (Base/USDC) or MPP. Ideal for AI agents doing occasional location lookups where signing up for a mapping service account is impractical.

## Known failure modes

- Invalid or out-of-range latitude/longitude values return an error
- Coordinates in the middle of an ocean or uninhabited area may return no address or a sparse result
- Payment failure (insufficient USDC balance or unsupported payment protocol) results in HTTP 402
- Server unreachable at IP-based hostname returns connection error

## How this service works

Pay-per-call geolocation utility for AI agents: geocoding, reverse geocoding, timezone lookup, and great-circle distance. No API key, no subscription — agents pay per request via x402 (Base/USDC) or MPP (Tempo/pathUSD).

## Output

Returns a structured address or place name corresponding to the provided latitude and longitude coordinates, typically including street, city, region, postal code, and country fields.
