* URL.
    * Email.
    * UUID.
    * ...and others.

All the validation is handled by the well-established and robust **Pydantic**.

### Security and authentication

Security and authentication integrated. Without any compromise with databases or data models.

All the security schemes defined in OpenAPI, including:

* HTTP Basic.

The `password` "flow" is one of the ways ("flows") defined in OAuth2, to handle security and authentication.

OAuth2 was designed so that the backend or API could be independent of the server that authenticates the user.

But in this case, the same **FastAPI** application will handle the API and the authentication.

So, let's review it from that simplified point of view:

          # - you are installing Scorecard on a *private* repository
          # To create the PAT, follow the steps in https://github.com/ossf/scorecard-action#authentication-with-pat.
          # repo_token: ${{ secrets.SCORECARD_TOKEN }}

          # Public repositories:
          #   - Publish results to OpenSSF REST API for easy access by consumers
