How this service works
Forward geocode an address (q=) or reverse geocode lat=+lon= using OpenStreetMap Nominatim. Returns up to 5 hits with display name and address parts. Community map data — not a postal authority.
Output
Returns up to 5 geocoding hits from OpenStreetMap Nominatim, each containing a display name (human-readable full address), structured address parts (street, city, county, country, postcode, etc.), and geographic coordinates. Results are community-sourced map data, not from a postal authority.
Example use cases
Address to coordinates for mapping
“I have the address '221B Baker Street, London, UK' — can you look up its latitude and longitude so I can pin it on a map?”
Reverse geocode GPS coordinates
“I've got coordinates lat=48.8584 and lon=2.2945 — what address or landmark is at that location?”
Validate and structure a user-submitted address
“A user submitted '10 Downing Street, Westminster, London' as their address — can you geocode it and give me back the structured address parts like city, postcode, and country?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/geocodeWhen to prefer
Choose this endpoint when you need lightweight forward or reverse geocoding backed by OpenStreetMap/Nominatim community data, especially for non-commercial or global address lookups. Ideal for agents that need to resolve place names to coordinates or coordinates to human-readable addresses without needing postal-authority accuracy. Good for automation pipelines that require affordable geocoding ($0.01/call) with structured address components. Prefer commercial geocoders (Google, HERE) when authoritative postal data or high result accuracy is critical.
Side effects
- No results found for ambiguous or misspelled address — returns empty array
- Missing required parameter (neither q nor lat+lon provided) — likely returns error
- Coordinates outside valid range (lat > 90, lon > 180) — may return empty or error
- Very new or obscure addresses not yet in OpenStreetMap — no results
- Rate limiting or payment failure for $0.01 USDC per call
