How this service works
Geocode address to coordinates - geocode an address or place name to latitude and longitude. Up to 10 matches: lat/lon, display name, structured address (road, city, state, postcode, country code), OSM type and id, importance and bounding box. GET ?q= OR ?address= OR ?query= OR ?lat=&lon= (reverse) OR ?sample=1|2|3 OR POST application/json with q|address|query. KEYLESS OpenStreetMap Nominatim - no key, no account, no signup. Returns a geocode_score 0-100 A-F with a RESOLVED / AMBIGUOUS /...
Output
Returns up to 10 match candidates, each containing: latitude/longitude, display name, structured address fields (road, city, state, postcode, country code), OSM type and ID, importance score, and bounding box. Also includes a geocode_score from 0–100 with letter grade (A–F) and a resolution status label such as RESOLVED or AMBIGUOUS.
Example use cases
Enrich customer records with coordinates
“I have a list of customer shipping addresses and I need to add lat/lon coordinates to each one — can you geocode '350 Fifth Avenue, New York, NY 10118' and return the coordinates along with whether it resolved cleanly or was ambiguous?”
Validate and normalize a delivery address
“Before I send a courier, can you check if '42 Wallaby Way, Sydney, Australia' geocodes to a real, unambiguous location and give me back the structured address with postcode and country code?”
Reverse geocode GPS coordinates to address
“I have GPS coordinates 48.8584 latitude and 2.2945 longitude — can you reverse geocode those to get the full display name and structured address including road, city, and country?”

Endpoint
GEThttps://6xrkjcfa3yrzvefcpvanurzou4.srv.us/api/geocode-address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, no-signup geocoding powered by OpenStreetMap Nominatim, especially for free-tier or high-privacy use cases where you don't want to share data with Google or HERE. It's ideal when you need structured address decomposition, OSM entity metadata, bounding boxes, and a built-in quality score (geocode_score with letter grade and resolution status) in a single call. Prefer alternatives like Google Geocoding API when you need the most up-to-date commercial POI data or guaranteed SLA.
Side effects
- Address not found in OSM: returns empty results array
- Ambiguous address: returns multiple candidates with AMBIGUOUS status and lower geocode_score
- Malformed or missing query parameter: returns error indicating required q, address, or query param
- Rate limiting from upstream Nominatim: may return 429 or timeout
- Very new or unmapped addresses absent from OSM data: no results or low-confidence match
