# Overview Welcome to Placekey! ## About Placekey You can use the Placekey API to retrieve a [Placekey](https://www.placekey.io/) for any location in the world, identifying it by its geographical coordinates or its address. If you give us the name of the place, your Placekey will contain a unique identifier for the POI that's located there. Placekey helps with entity matching for places and addresses. With Placekey you can dedupe, match, sync, and merge physical places. ## Placekey Developer Portal The [Placekey Developer Portal](https://placekey-portal.us.auth0.com/u/signup?state=hKFo2SBZV1lBMFNpSWNIb2NTN0dNVkJqT3hlOU9BRUhEOEp0baFur3VuaXZlcnNhbC1sb2dpbqN0aWTZIEo1TEZWT2duRlRSRkFHRFNkUGg0bGUzUGdkQkZXeGZjo2NpZNkgU0pyaHh2aks4bFhmWkV0bDFRM1FodzJvTWFMTnJ6NEw) is where you get access to the API, review your usage, and generate API keys. ## Placekey Libraries We have worked with a community to build libraries for Python and Javascript that allow you to perform geometric operations with Placekeys. * Python - [placekey](https://pypi.org/project/placekey/) * JavaScript - [@placekey/placekey](https://www.npmjs.com/package/@placekey/placekey) ## Help and Support If you have any feedback or if you need help, please contact us on or email . --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
