Place autocomplete API for administrative regions

Meridian is a place autocomplete API: as someone types a region name, you get ranked suggestions with the containing state, country, and nested municipalities — ready for an address or coverage picker.

What a place autocomplete API is for

Place autocomplete is typeahead over named places. Users rarely type a full official name. They type “Lisb”, “Bretagne”, or “King County” and expect the right administrative region, disambiguated from namesakes. Meridian indexes normalized names and display names so prefix queries stay fast under debounce.

It is not a street-level geocoder and not a business listings API. If you need rooftop coordinates for a house number, use a geocoder. If you need a production autocomplete over states, counties, municipalities, and parishes — with hierarchy — this is the API.

Hierarchy in the same response

Each hit includes a UI-ready title and subtitle plus the stored location: parents, children, lineage, and region type. Your client can render an autocomplete row, then expand child regions without a second gazetteer.

Country-scoped search

Pass lang (for example us, nl, de) to search one country index. That keeps “Washington” and homonyms in the right market. Live demo coverage is listed on the coverage page; the API docs describe GET /locations/search.
