        This is documentation for client Pleroma API. Most of the endpoints and entities come
        from Mastodon API and have custom extensions on top.

        While this document aims to be a complete guide to the client API Pleroma exposes,
        the details are still being worked out. Some endpoints may have incomplete or poorly worded documentation.
        You might want to check the following resources if something is not clear:
        - [Legacy Pleroma-specific endpoint documentation](https://docs-develop.pleroma.social/backend/development/API/pleroma_api/)
        - [Mastodon API documentation](https://docs.joinmastodon.org/client/intro/)
        - [Differences in Mastodon API responses from vanilla Mastodon](https://docs-develop.pleroma.social/backend/development/API/differences_in_mastoapi_responses/)

        Please report such occurences on our [issue tracker](https://git.pleroma.social/pleroma/pleroma/-/issues). Feel free to submit API questions or proposals there too!
