Autosuggest API

Introduction

This endpoint suggests address or place candidates based on an incomplete or misspelled query, from which the user selects the best query to submit.

The Autosuggest API provides comprehensive responses to free-form user queries by returning suggestions for:

unknown places from a category or chain, such as "hospitals".
unknown places at known locations, such as "London museums".
known places with known names, such as "Times Square" or "Paris".
known and unknown places for partial queries, such as "hosp", "London muse", "Times S" or "Par"

NOTE: The response may contain experimental elements not documented here. Any undocumented element is subject to removal at any time.
