API and MCP access for developers
Connect via REST API at /api/v1 or link an MCP server to search launches and manage listings.
Updated
Access methods
Two integration paths are available. The REST API at /api/v1 serves OpenAPI 3.1 schema at /api/v1/openapi.json. An MCP server at /mcp connects AI assistants—Claude, ChatGPT and other MCP clients—directly to launch and listing data.
What you can do
Both methods let you search launches and read listings. MCP clients can additionally draft and manage your own listings, subject to your permission settings.
Voting is not available through the API.
Authentication
Sign in via OAuth (your assistant opens a sign-in page on this site) or use a personal API key from /account/developers. Keys display once only; only the hash is stored on file.
Costs and constraints
Rate limits and daily quotas apply to all API requests. Payments occur on this site; the API returns a checkout link when needed.
Full technical documentation is at /developers.
