What is geocoding?
Geocoding turns a place written the way people write it, an address, a business name, a neighbourhood, into a latitude and longitude your software can use. Reverse geocoding does the opposite: it takes coordinates and returns the nearest named place, which is how a dropped pin or a phone's GPS fix becomes a readable address.
How much does geocoding cost?
Every endpoint draws from one monthly unit pool shared across maps, geocoding and routing. Autocomplete is 0.1 unit per call, a full search and a reverse lookup are 1 unit each. There are no per-product SKUs to reason about and no separate geocoding bill.
Is there a free tier?
Yes. The free plan includes 10,000 units a month with no card and no sales call, which is 100,000 autocomplete calls if that is all you spend them on. It is a hard cap, so a runaway loop cannot produce a bill.
Which languages can results come back in?
English, German and French, or local names if you ask for none of them. A result without a name in the language you requested falls back to its local name rather than disappearing from the response.
Can I bias or restrict results to a region?
Two ways. Bias ranking toward a point, so a search for 'Springfield' from Utrecht prefers the nearby one. Or restrict results to a bounding box outright. Reverse lookups take a search radius.
What shape do the results come back in?
A GeoJSON FeatureCollection. Coordinates sit in the standard geometry field and the structured address (name, street, house number, postcode, city, state, country) sits in properties. It drops straight into MapLibre, Leaflet, OpenLayers, PostGIS or anything else that speaks GeoJSON, with no custom envelope to unwrap first.
Can I store or cache the results?
Yes, and caching what you already paid for is not a second call. There is no separate permanent-geocoding product and no per-result storage tier. The underlying place data comes from open data under the ODbL licence, so the usual open-data attribution applies if you publish a derived database, the same condition every provider in this category works under.
How fresh is the place data?
The index is rebuilt weekly from open data, so new streets, renamed businesses and freshly numbered addresses arrive within days rather than at a quarterly release cadence.
Where is coverage weakest?
The index is built from open data, so it is as good as the open data is: dense across Europe and in most cities worldwide, thinner in rural areas of countries where addresses are rarely mapped. If you need rooftop-level parcel accuracy in the United States, a national address product will still beat any open-data geocoder, this one included. Try your own addresses in the panel at the top before you decide.
Where are my requests processed?
In the European Union, end to end. No part of the request path touches a US-controlled provider, which is what makes the GDPR and data-residency conversation short. We publish a DPA and a full sub-processor list.
