Below we provide example Bark Financial API routes. For LLM use, these are translated to tool definitions in Python.

Authentication

GET /user/id

Obtain an id for the user. A user id is required to call other endpoints that return or modify user specific data.

When used by a LLM agent, the harness will manage the user id. The agent may use the special string <user_id> as a placeholder in subsequent requests. If a user id is not available, all requests that require one will immediately fail.

User id will automatically be available for logged in users.

Parameters:

• first_name: String
• middle_name: String
• family_name: String
• dob: String
• ssn_last_lour: Integer

Response:

• ✅ 200 OK
• ❌ 401 Unauthorized
• ❌ 400 Bad Request
• ❌ 422 Unprocessable Entity

POST /user/mfa-sms

Send a multi factor authentication code to the user’s phone number on file.
