-1. Check the
-   [Pricing page](https://github.com/chargeprice/chargeprice-api-docs/blob/master/plans.md)
-   for information on the current plans at Chargeprice. There should be a free tier up to a certain
-   limit of API calls per month.
-2. Contact [contact@chargeprice.net](mailto:contact@chargeprice.net), stating that you would like to
-   contribute to the development the open source EVMap app and therefore need access to the
-   Chargeprice API for testing.
-3. When your access to the API is approved, you will receive an API key via email.
+Since February 2022, the Chargeprice API is no longer available for free to new customers. However,
+you can use their
+[staging API](https://github.com/chargeprice/chargeprice-api-docs/blob/master/test_the_api.md)
+for free to test the Chargeprice features. This is already
+[configured](https://github.com/johan12345/EVMap/blob/master/app/src/debug/res/values/donottranslate.xml)
+by default for the debug version of the app, so you can leave the `chargeprice_key` field in your
+new `app/src/main/res/values/apikeys.xml` file blank. Note that the staging API contains only a
+limited dataset, so it only outputs prices for certain charge point operators and payment plans (see
+[here](https://docs.google.com/document/d/14zlFr5IEhhR3uGXO5QePKjNUQANVwA-Ba-cZbOCiOBk/edit) for
+details).

+In case you want to pay for access to the full Chargeprice API, check out their
+[API docs](https://github.com/chargeprice/chargeprice-api-docs) on GitHub and contact them at
+[sales@chargeprice.net](mailto:sales@chargeprice.net).
