Hub Protocol Authentication

Token-based authentication for Hub Protocol

Generate Access Token​

The Hub requests a temporary access token from the Data Pod:

POST /trpc/hub.generateAccessToken
{
  "requestId": "req-123",
  "scope": ["preferences", "calendar", "tasks"],
  "expiresIn": 300 // 1-5 minutes
}

Response:

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "expiresAt": 1737360000000,
  "requestId": "req-123"
}

Token Usage​

Use the token in subsequent requests:

GET /trpc/hub.requestData
Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

Token Security​

  • Time-limited: Maximum 5 minutes validity
  • Scope-based: Only authorized data types
  • Non-reusable: Tied to unique requestId
  • Audit trail: All token generation logged
