How this service works
Forward and reverse geocoding on OpenStreetMap data: turn place names, addresses, and landmarks into coordinates with structured address components (forward), or turn lat/lon into the nearest address (reverse). Global coverage, up to 10 ranked results. ODbL attribution included in every response. POST a JSON body like: {"query":"eiffel tower, paris","limit":1}
Output
An array of up to 10 ranked results, each containing latitude, longitude, structured address components (street, city, country, etc.), display name, and ODbL attribution metadata from OpenStreetMap.
Example use cases
Example prompt
“Can you geocode 'Times Square, New York City' and give me back the coordinates and structured address — return the top 1 result?”
Technical details
Endpoint
POSThttps://keyronne.com/api/geocodeWhen to prefer
Use this endpoint when you need global forward or reverse geocoding backed by OpenStreetMap data with structured address components and ranked results. Prefer this over proprietary geocoders when ODbL-compatible open data is acceptable and you want a pay-per-call model at $0.003 per request without subscription overhead.
Side effects
- Ambiguous or misspelled query returns low-confidence or irrelevant results
- Providing both query and lat/lon simultaneously may cause undefined behavior
- Coordinates outside valid range (-90 to 90 lat, -180 to 180 lon) rejected with validation error
- limit exceeds maximum of 10 returns error
- No matching location found returns empty results array
- Payment not included or insufficient USDC returns 402 error
