## 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 toll402-reverse-geocode-06bda0d4 -d '<json body>'
```

Example prompt: What's the street address at coordinates 37.7749° N, 122.4194° W? Use zoom level 18 for maximum detail.

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call reverse geocoding call without signing up for a mapping API key, especially within an x402-compatible agent wallet workflow on Base. Ideal for sporadic or low-volume lookups billed at $0.002 USDC per call with no monthly commitment.

## Known failure modes

- Coordinates out of valid range (lat > 90 or < -90, lon > 180 or < -180) returns a validation error
- Remote geocoding service unavailable returns a gateway error
- Coordinates in an ocean or uninhabited area may return minimal or empty address data
- Payment failure (insufficient USDC balance) returns HTTP 402
- Invalid body type or missing required fields returns a schema validation error

## Output

A JSON object with ok:true and location data — typically including a formatted address, street name, city, country, and other administrative details corresponding to the given lat/lon coordinates at the requested zoom level.
