# Reverse Geocoding – Coordinates to Address

> Reverse Geocoding – Coordinates to Address is a paid API for AI agents from mcpfax-utility.bowling-anthony.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Converts geographic coordinates (latitude/longitude) into the nearest human-readable street address.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 reverse-geocoding-coordinates-to-address-f6052efe
```

Example prompt: What's the street address at coordinates 40.7580° N, 73.9855° W? I need the full postal address for that location.

## When to prefer this

Use this endpoint when you have raw latitude/longitude coordinates and need a human-readable address — e.g. from GPS hardware, photo EXIF data, map clicks, or device location APIs. Prefer this over forward geocoding when you already have coordinates and need the address, not the other way around.

## Known failure modes

- Coordinates over open ocean or remote wilderness may return no address or only a country/region
- Invalid or out-of-range coordinate values (e.g. lat > 90) return a validation error
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Ambiguous results in areas with poor geocoding data coverage

## How this service works

Reverse geocoding — Coordinates → nearest address.

## Output

Returns the nearest street address for the given coordinates, typically including street number, street name, city, region/state, postal code, and country.
