Address autocomplete API

An address autocomplete API suggests complete, valid addresses as the user types, and returns the one they pick as structured data: street, city, postcode, country and coordinates.

PlaceKit is that API, worldwide, in a single REST endpoint. Typo tolerant, ranked by the user’s location, reverse geocoding included, and 10,000 requests free every month with every feature unlocked.

How it works

Create a free account, copy your public API key, and drop the autocomplete library into your form: a few lines of JavaScript and the field is live. From a back-end, or from any other language, post a query to https://api.placekit.co/search and read the results.

Each result comes back complete (name, city, county, administrative area, country, postcode, latitude and longitude), so the form can be filled and the pin dropped without a second call. Coordinates to address works the same way on /reverse.

What the API gives you

One endpoint, one counter, and everything an address field needs.

Worldwide coverage: Addresses, streets, cities, administrative areas and countries in 246 of the 249 ISO 3166-1 countries, at the same price everywhere. Data comes from OpenStreetMap, enriched with national datasets such as the French BAN and with GeoNames.
Typo tolerance and instant results: Search is powered by Algolia, so suggestions come back at every keystroke and survive misspellings, missing accents and inverted words.
Geolocation-based ranking: Ask the browser for the device location, or fall back to the IP location, and results closest to the user are ranked first. It is the fastest way to cut an address down to two or three keystrokes.
Reverse geocoding included: The same API turns coordinates into the surrounding addresses. Every autocomplete result already carries latitude, longitude and the parsed address parts, so there is no second "details" call to make or to pay for.
Live patching: Add a missing address or fix a wrong one yourself and it is served to your users instantly. We then review the patch and merge it back into the global dataset.
SDKs for the stack you use: Autocomplete JS for vanilla JavaScript, Autocomplete React for React, and a zero-dependency Client JS for front-end and back-end calls. Everything else can hit the REST API directly, documented with OpenAPI.
GDPR compliant, no lock-in: PlaceKit is a French company. We never sell, share or trade your users’ data, and our terms let you store the results and display them on any map provider.
Predictable billing: Every API call counts as one request, whatever the number of results returned. Follow usage in real time and set a monthly self-limit per app so an unexpected traffic spike can never turn into an unexpected invoice.

PlaceKit vs. Google Places Autocomplete

Google list prices in US dollars for the first 100,000 monthly events, as published by Google Maps Platform on September 6, 2026. PlaceKit prices are the standard grid. Google wins on business listings and rooftop precision, PlaceKit on simplicity, freedom of use and price predictability. A longer breakdown lives on our Google Places alternative page.

Frequently asked questions

Is there a free address autocomplete API?

Yes. PlaceKit gives you 10,000 requests every month for free, with every feature unlocked and no credit card required. Beyond the free quota you pay per request, from $0.0030 down to $0.0010 depending on your monthly volume. Tiers are graduated: after the free 10,000, each tier price applies only to the requests falling in that tier.

What is the difference between address autocomplete, address completion and address autofill?

They are three names for the same feature: an API that suggests complete, valid addresses while the user types, and returns structured data (street, city, postcode, country, coordinates) for the one they pick. "Autocomplete" usually describes the suggestion list, "autofill" the moment the form fields are filled from the selected suggestion, and "address completion" is used interchangeably with both. A single PlaceKit integration covers all three.

Does it work worldwide, and in France?

Yes. PlaceKit covers 246 of the 249 ISO 3166-1 countries. The catalog is built from OpenStreetMap, enriched with country-specific datasets such as the Base Adresse Nationale (BAN) for France, and with GeoNames. Results are returned in their local language, with English and French translations available.

How is it different from Google Places Autocomplete?

For plain autocomplete requests the list prices are close: $2.83 per 1,000 at Google versus $3.00 then $2.40 at PlaceKit. The gap opens when you need the actual address data, because Google bills a separate Place Details call at $5 to $20 per 1,000 to get coordinates and address parts while PlaceKit includes them in every result. On top of that, Google splits address entry across several APIs and SKUs billed through session tokens, and requires results shown on a map to be on a Google Map: PlaceKit is one endpoint, one counter, and results you can display on any map. Google remains the reference for business listings and rooftop-level coordinates.

Can I use it for a store locator or a city search?

Yes. The same autocomplete powers travel and city search (filter results by type to get cities only) and checkout address autofill. A dedicated store locator, where you define your own points of interest and rank them by distance to the user, is in beta.
