  title: Have I Been Pwned API v3 Breach Subscription API
  description: Version 3 of the Have I Been Pwned API. Authenticated APIs for breaches by account, pastes, domain search, domain verification, stealer logs, and subscription status require both the hibp-api-key and user-agent headers. Availability varies by subscription tier and is noted per operation. The Pwned Passwords range API is free and does not require authentication.
