Create a new user

Create a new user (individual or business) in the system.

Automatic Verification: When a user is created with all required fields, Kira automatically triggers identity verification (KYC/KYB) in the background:

  1. No additional API calls needed - Verification starts automatically
  2. Faster onboarding - Users don't need to complete a separate verification step
  3. Webhook notifications - You'll receive user.verification.accepted or user.verification.failed events

The response includes a verification_triggered field indicating whether automatic verification was started.
