API key

Manage your subscription or purchase an API key to begin integrating HIBP into your own app.

Making calls to the HIBP email address search API requires a rate limited key you can purchase on either a monthly or yearly basis, starting at US$3.50 per month. If you've already purchased a key, you'll be able to manage it after verifying you have access to the email address you wish to use (you'll receive a unique link to that address). If you need help, check out the FAQs and troubleshooting guide or submit a support request.
