Placekey

Placekey is a free, universal identifier for any physical place, designed to make it easy to join and match address and point-of-interest data across disparate datasets. The Placekey API resolves an address or latitude/longitude into a single Placekey, supporting both single and bulk (up to 100 per batch) lookups for address matching, deduplication, and data enrichment.

Placekey publishes 2 APIs on the APIs.io network: Bulk API and Lookup API. Tagged areas include Location, Geocoding, Address Matching, Identifiers, and POI.

Placekey’s developer surface includes authentication, documentation, and 8 more developer resources.
