## 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 afterwren-reverse-geocoder-1edb1c1b
```

Example prompt: What's the street address at coordinates 37.7749° N, 122.4194° W? I need to reverse geocode those coordinates into a real place name.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call reverse geocoding solution without a subscription, especially as an alternative to deprecated or expensive geocoding APIs. Ideal for agents needing occasional coordinate-to-address lookups without committing to a geocoding platform contract.

## Known failure modes

- Missing lat or lng parameters returns an error
- Invalid or out-of-range coordinate values may return no results
- Coordinates in remote or unmapped areas may return incomplete address data
- Payment failure (402) if x402 payment header is missing or insufficient
- Network timeout for slow upstream geocoding resolution

## How this service works

Retired APIs, back in one key. Clearbit API alternative, geocoder and Goodreads API replacement: one REST API + MCP server Try it free in one click, no sign-up.

## Output
