# Current User Profile

> Retrieves the authenticated user's profile from Auth0 and local database.

This endpoint handles user auto-registration: if the user exists in Auth0 
but not in the local database, they will be automatically registered.

Returns the user's default (first) account regardless of any `x-account-id` header.




## OpenAPI

````yaml GET /api/v1/auth/me
openapi: 3.1.0
info:
  title: AION Authentication Service API
  description: >
    Authentication and user management service for the AION platform.


    This service provides:

    - JWT and API key validation

    - User profile management

    - API key lifecycle management

    - User invitation and team management


    ## Authentication


    Most endpoints require authentication via one of:

    - **Bearer Token (JWT)**: OAuth2/OIDC tokens from Auth0

    - **API Key**: Service-generated API keys for machine-to-machine
    authentication


    Protected endpoints also require the `x-account-id` header to specify the
    account context.


    ## Error Handling


    All errors follow a consistent format with error codes prefixed by category:

    - `AUTH_*`: Authentication errors

    - `USER_*`: User management errors

    - `ACCT_*`: Account errors

    - `ROLE_*`: Role/permission errors

    - `APIKEY_*`: API key errors

    - `GEN_*`: General errors
