The Bluesky API, powered by the AT Protocol (Authenticated Transfer), provides a decentralized infrastructure for social networking. Unlike legacy social platforms that have pivoted toward restrictive, high-cost API tiers, Bluesky offers a transparent, developer-first environment where agents can read, write, and interact with the social graph... Reviewed from official documentation.
REST API (XRPC) The AT Protocol uses a custom remote procedure call system called XRPC, which is essentially a set of RESTful conventions over HTTP. Every action (query or procedure) is defined by a Lexicon (schema).
For Humans 1. Create a Bluesky account at bsky.app(https://bsky.app). 2. Navigate to Settings > Advanced > App Passwords. 3. Click Add App Password, name it (e.g., "Rhumb-Agent-Alpha"), and copy the generated string. 4.
Value :--- 160ms 380ms 640ms 3,000 requests / 5 min 99.9% --- Idempotency: The API does not natively support idempotency keys.
