How this service works
Reverse geocode - street address, city, state, postcode and country for any latitude and longitude (OpenStreetMap)
Output
Returns a JSON object containing a display_name string (full human-readable address), a structured address object with fields like road, city, state, postcode, and country, plus latitude/longitude, bounding box, OSM metadata (type, category, name), data source attribution, and a checked_at timestamp.
Example use cases
Field photo geotagging lookup
“I have a photo taken at latitude 37.7749, longitude -122.4194 — can you tell me the full street address and city those coordinates map to?”
Delivery driver location check
“A driver just checked in at coordinates 51.5074 N, 0.1278 W — what's the actual street address and postcode there so I can confirm their location?”
App log coordinate enrichment
“My app logged a user event at lat 48.8566, lon 2.3522 — what city, country, and full address does that location correspond to?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/geocode/reverse?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert raw GPS coordinates (latitude/longitude) into a human-readable postal address backed by OpenStreetMap data. It costs $0.01 USDC per call via x402 payment, making it suitable for per-query agent workflows. Prefer it over forward geocoding endpoints when you already have coordinates and need address details. It is distinct from the sibling forward-geocoding endpoint which does the reverse direction (address-to-coordinates).
Side effects
- Coordinates in ocean or remote wilderness may return no address or sparse results
- Invalid lat/lon values (out of range, non-numeric) will cause a request error
- Coordinates near borders may return ambiguous or unexpected administrative divisions
- OpenStreetMap coverage is incomplete in some rural or developing regions, yielding partial addresses
- Rate limiting or upstream Nominatim outages may cause timeouts or 5xx errors
