User Trust API

The User Trust API is the foundational component of the Autheona platform. It allows you to programmatically verify the trustworthiness of a user, providing essential risk assessment data to secure your application and protect your operations.

By integrating the User Trust API, you can perform real-time checks to determine if a specific user account meets your platform safety standards. This API is critical for preventing fraud, ensuring policy compliance, and maintaining a secure environment for your customers.

  -d '{
    "email_address": "<email-address>"
  }'
