  title: Have I Been Pwned API v3 Breached Accounts API
  description: 'The Have I Been Pwned (HIBP) API allows the list of pwned accounts (email addresses, domains,

    passwords, and stealer log entries) to be quickly searched via REST. Authenticated endpoints

    require an `hibp-api-key` header. All requests must send a `user-agent` header that accurately

    identifies the consuming application. Subscriptions range from Pwned 1 to Pwned 5.
