# SiteCheck Geocode

> SiteCheck Geocode is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Converts a place name to geographic coordinates (forward geocoding) or coordinates to a place name (reverse geocoding) using OpenStreetMap/Nominatim data.

## Facts

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 sitecheck-geocode-8e01f6a4
```

Example prompt: What are the latitude and longitude coordinates for Berlin, Germany?

## When to prefer this

Choose this endpoint when you need a simple, pay-per-call geocoding lookup without managing API keys for Google Maps or similar services. It is ideal for AI agents that occasionally need coordinates for a place name or want to reverse-geocode a coordinate, especially when already using other SiteCheck tools. Results are cached for 7 days, making it cost-efficient for repeated lookups of common cities.

## Known failure modes

- Place name not found or too ambiguous — empty results array returned
- Invalid or out-of-range lat/lon for reverse geocoding — empty or error response
- Missing required query parameter (neither q nor lat/lon provided) — likely 400 error
- Rate limiting or upstream Nominatim unavailability — service error
- Truncated or misspelled place names may return wrong or no results

## How this service works

Place names to coordinates and back: up to 5 matches for a name, or the place at a coordinate. Each match has a display name, latitude and longitude, country code and type. Attribution: © OpenStreetMap contributors, ODbL. Results are cached seven days.

## Output

Returns a JSON object with the original query, results array containing lat/lon, place name, type (e.g. administrative), country code, and display name, plus a source attribution string, checkedAt timestamp, and OpenStreetMap attribution notice. Results are cached for 7 days.
