API and MCP docs, without detours.

Authentication

Every request uses a Bearer token in the Authorization header.

Authorization: Bearer YOUR_API_KEY

Your key is scoped to your subscribed bundles. Calls to unsubscribed services return 403.

Read-only MCP

MCP v1 is for AI supported lookup, scoring, summaries, and recommendations. Tools use the li_ prefix and do not write, send, create, update, delete, schedule, charge, notify, or call external side effecting systems.
