Support
& sales.
One form for everything — integration help, a higher request limit, an enterprise agreement, security reports, or a privacy request. Pick a topic and a real engineer answers.
The free tier covers 1,000 requests per hour (~720K/month) — full signal set, production traffic, no credit card. Need more? Tell us your expected volume and we'll arrange a custom enterprise limit. Hospital, public body, university or non-profit? The public-interest program removes the cap entirely.
Sales, support and security — one inbox, same business day.

Common reasons to contact us
Maskbreak is free: 1,000 requests/hour (~720K/month), every signal, no card and no expiry. There is no paid tier. If your volume outgrows that, or your security and procurement teams need a DPA, an SLA or a signed agreement, write to us.
Hospitals, public health, government, election offices, emergency services, universities and the non-profits that fight abuse get the API with the hourly cap removed. Free, no expiry. The application form has its own page; institutional email domains are fast-tracked.
Our security engineers can help you design the right integration pattern for your stack — whether that's server-side API calls, the JavaScript SDK, or webhook-based alerting.
Responsible disclosure, partnership inquiries, or questions about specific detection signals. See our responsible disclosure policy for vulnerability reporting.
Maskbreak is built and operated by a small team of security engineers focused exclusively on fraud and bot detection. We don't outsource support — when you email us, you get an engineer who has read your integration logs.
