The Loom API is a managed HTTPS service. All routes are versioned under /v1:

​
Authentication

Every request authenticates with a bearer credential that resolves to a workspace (org_id). Per-user operations also need a user_id.
1

API key

Authorization: Bearer <key> — create keys in the dashboard. Add X-User-Id for per-user operations. Best for servers and agents.
2

Session token (JWT)

Authorization: Bearer <token> from signup/login. Claims carry user_id, org_id, name, email. Best for interactive apps.
See Authentication for the full guide.
Founder-only endpoints (everything under /v1/admin/* except /admin/me) require an account with founder access, else 403.
