How do I access the API and MCP server?
Connect via REST API at /api/v1 or use MCP for AI assistants to search and manage launches on your behalf.
Updated
REST API: direct access to launch data
Your launch window data lives at /api/v1. Find the full OpenAPI 3.1 specification at /api/v1/openapi.json to build your own integrations. Everything you need is in the docs at /developers.
MCP: AI assistants in mission control
Connect Claude, ChatGPT or other MCP clients to our remote server at /mcp. Your AI assistant can then:
- Search active launches and read listing details
- Draft new listings and manage existing ones (with your permission)
This turns your assistant into a co-pilot for launch operations.
Getting authenticated
Two ways to sign in:
- OAuth: Your assistant opens a sign-in page on this site when you first connect.
- Personal API key: Generate one at /account/developers. Keys display once only; we store only a hash.
What you need to know
Rate limits and daily quotas apply to all requests. Any payment is processed on this site itself—the API returns a checkout link when needed. Note: voting is not available through the API. Head to /developers for full technical guidance and code samples.
