Geocoding & Reverse Geocoding API

Address to coordinates, coordinates to address.

About this API

Geocoding is a foundational agent tool. This API handles forward geocoding (address to coordinates) and reverse geocoding (coordinates to address), with a confidence score and normalized components.

It is designed for chaining: the response is small, stable and includes a `place_id` so an agent can refer to the same place across calls. The preview uses OpenStreetMap Nominatim with a proper user agent and caching. For production volume, swap in a commercial geocoder behind the same response shape.

For AI agents

Convert a free-text address or place into coordinates and a normalised address, or reverse geocode coordinates.

Scope

Does not validate postal deliverability or rooftop accuracy. Uses OpenStreetMap data and is not a legal boundary source.
