  version: '1.0'
  description: 'XRPC is the AT Protocol''s HTTP-based RPC layer. All protocol interactions

    are exposed as XRPC methods identified by an NSID and reached at

    `/xrpc/{nsid}`. Query methods use GET; procedure methods use POST.

    Bluesky AppView endpoints live under `https://api.bsky.app`; PDS-hosted

    methods are reached at the user''s PDS host (e.g. `https://bsky.social`).
