# LocationAPI - **Start here** - [Introduction](/docs): Unwired Labs LocationAPI locates IoT, M2M and other connected devices from visible cell towers and WiFi networks, without needing GPS. - Get started - [Authentication](/docs/authentication): Every request to Unwired Labs' APIs must be authenticated with a scoped access token. Keep tokens server-side and rotate them regularly. - [Endpoints](/docs/endpoints): Unwired Labs' APIs are hosted in two regions, each with its own base URL. Choose the region closest to your servers. - **APIs** - Geolocation - [Geolocation](/docs/geolocation): Locate IoT, M2M and other connected devices anywhere in the world without GPS using cell tower and WiFi data. - [Getting Started](/docs/geolocation/getting-started): A four-step walkthrough for integrating the Geolocation API, from sending cell data to handling low-confidence results. - [Usage](/docs/geolocation/usage): Ready-made cURL, PHP, Python and JavaScript examples for the Geolocation API, plus an interactive sandbox. - Request - [Request](/docs/geolocation/request): Top-level Geolocation request parameters, fallback options, address and border-threshold settings. - [Cells](/docs/geolocation/cells): Cell tower objects, supported radio types and the parameters accepted for each. - [WiFi](/docs/geolocation/wifi): WiFi access-point objects, their limits and the parameters accepted. - [GPS](/docs/geolocation/gps): Contribute GPS observations alongside cell and WiFi data to improve positioning accuracy. - [Response](/docs/geolocation/response): Geolocation response fields, address detail components and metadata returned when enabled. - [Errors](/docs/geolocation/errors): Exact Geolocation error messages and what each one means. - [Balance](/docs/balance): Check the count of request credits left in your account for the day, and available device slots for device plans. - **Other** - Sunsetting APIs - [Geocoding](/docs/geocoding): Convert addresses to geographic coordinates (forward geocoding) and coordinates back to human-readable addresses (reverse geocoding). - [Timezone](/docs/timezone): Look up time offset data for any location on the surface of the earth, including DST handling. - [Maps & Static Maps](/docs/maps): LocationIQ Maps and Static Maps, Unwired Labs offerings, have moved to the LocationIQ documentation.
