  title: Pixelfed REST Accounts Collections API
  description: 'Mastodon-compatible REST API for the Pixelfed federated photo-sharing platform. Provides endpoints for accounts, statuses, timelines, media, notifications, search, collections, stories, direct messages, and instance/federation metadata. All authenticated calls use OAuth2 Bearer tokens. Every Pixelfed instance exposes this API independently at its own domain; there is no single central API host.
