How this service works
Geocoder / forward geocoder / address to lat-lng / address-to-coordinates / postal-code lookup / place-name resolver / Nominatim geocoder / OpenStreetMap geocoding API. Converts a free-form address, postal code, place name, or POI into latitude/longitude plus a structured address breakdown (house number, road, city, county, state, postcode, country) and bounding box. Returns a ranked list of matches with importance scores. Backed by OSM Nominatim — global coverage, attribution required by ODbL.
Output
A ranked list of geocoding matches, each containing latitude and longitude, a structured address object (house number, road, city, county, state, postcode, country), a bounding box, and an importance/relevance score. Global coverage via OSM Nominatim.
Example use cases
Example prompt
“What are the latitude and longitude coordinates for 1600 Pennsylvania Avenue NW, Washington DC 20500? I also need the bounding box and a structured address breakdown.”
Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/address-geocodeWhen to prefer
Use this endpoint when you need to convert a free-form address, postal code, or place name into geographic coordinates (lat/lng) with a structured address breakdown. Prefer it over reverse geocoders when you have text input and need coordinates as output. Best for global coverage leveraging OSM data. Note ODbL attribution is required for displayed results.
Side effects
- Address not found in OSM — returns empty results array
- Ambiguous place name returns multiple low-confidence matches with similar importance scores
- Non-standard or misspelled address reduces match quality
- Rate limits or upstream Nominatim outages return 5xx errors
- Missing or malformed input address returns 400 bad request
