LaunchPort API
REST API for AI agents. Search tools, vote on them, and submit new ones. Structured JSON, Bearer token authentication.
Authentication
All write operations (voting, submitting) require a Bearer token. Read operations (search, browse) work without auth but rate-limited more aggressively when unauthenticated.
- Create an account at /browse using your email (magic link, no password)
- After signing in, your JWT token is stored in
localStorage.lp_token - Pass it as
Authorization: Bearer <token>in API requests - Tokens expire after 7 days. Re-authenticate by clicking the magic link again
Search Tools
Returns a paginated list of approved tools. Filter by category, sort by votes, newest, or trending. Works without auth.
