TL;DR

What is the Bluesky API?

Public AT Protocol profiles, author feeds, and threads as the same JSON shape as our other platforms — no AT Protocol client. Every endpoint is a single authenticated GET request that responds with predictable JSON, so the data drops straight into dashboards, AI pipelines, RAG systems, and no-code automations. AI agents can call the same endpoints as MCP tools via @captapi/mcp.

Compared with Bluesky AT Protocol: Do not pay Captapi to avoid a Bluesky OAuth wall — there isn't one for public reads. Use Captapi when you already hold a Captapi key and want a Bluesky profile, author feed, or thread in the same envelope as Instagram and TikTok. Bluesky AT Protocol alternative.

Frequently asked questions

What is the Bluesky API?+

The Bluesky API is a REST API from Captapi that returns public Bluesky data as clean, structured JSON. It covers 3 endpoints — Profile, User Posts, Post Details — behind one Bearer API key, with no OAuth flow and no infrastructure to build or maintain.

What data can I get from the Bluesky API?+

Public AT Protocol profiles, author feeds, and threads as the same JSON shape as our other platforms — no AT Protocol client. Each endpoint is a single GET request that responds with predictable JSON fields, so the data is ready for dashboards, AI pipelines, and automations.

Do I need a Bluesky developer account or OAuth?+

No. You only need a Captapi key (capt_live_...), sent as an Authorization: Bearer header. The same key works across all 33 platforms Captapi supports. We handle access, rate limits, retries, and parsing for you.

How much does the Bluesky API cost?+

Bluesky endpoints cost between 1 and 3 credits per call, depending on the endpoint and how many results you request. New accounts start with 100 free credits (no credit card). Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d.

Can AI agents use the Bluesky API?+

Yes. Every Bluesky endpoint is exposed as a tool in the official MCP server (@captapi/mcp) for Claude, Cursor, and VS Code, and is also available through the @captapi/cli CLI and the n8n-nodes-captapi community node.

Is the Bluesky API suitable for production use?+

Yes. It is a stable REST API with predictable JSON, automatic retries, and upstream fallbacks. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Only successful responses consume credits — failed or empty results are never charged.

Does Bluesky require OAuth for public reads?+

No. AppView getProfile / getAuthorFeed / getPostThread are already public. Captapi is a normalized JSON client (isRepost marked, embeds as external | images | video | quote) on the same key as the rest of the catalog — not a way around an auth wall. Bluesky-only jobs can call the AppView directly. App passwords are for writes; we do not post, like, or follow.
