Access our API and MCP for developers
Query launches via REST API at /api/v1 or connect an AI assistant over MCP to search and manage listings.
Updated
Connect via REST API
The REST API is at /api/v1. Retrieve the OpenAPI 3.1 description at /api/v1/openapi.json to understand all available endpoints and parameters.
Sign in using OAuth or a personal API key from /account/developers. Note that API keys are shown once only; only a hash is stored after that.
Connect an AI assistant over MCP
Run an MCP server at /mcp. Claude, ChatGPT and other MCP clients can connect to search launches across the calendar, read individual listings and—with your permission—draft and manage your own product listings.
Your assistant will open a sign-in page on this site if it needs to authenticate.
Quotas, payments and what you cannot do
Rate limits and daily quotas apply to all requests. When you trigger a paid action, the API returns a checkout link; all payments happen on this site, not through the API itself.
Voting on launches is not available through the API or MCP.
Full documentation is at /developers.
Questions people ask
- How do I authenticate with the API?
- Use OAuth or create a personal API key at /account/developers. Keys display once; save it securely as only a hash is retained.
- Can my AI assistant manage listings on my behalf?
- Yes. Over MCP, an AI assistant can search launches, read listings and draft or manage your own listings if you give permission.
- Where do I pay for API usage?
- Payments happen on this site via checkout link. The API returns the link when needed; no billing occurs off-site.
