Hey PH 🖐️

You and I have both shipped a free plan, so we know the pattern: Abuse usually doesn't happen at signup. It happens after. The accounts look perfectly normal at the door. Then the credits disappear within 72 hours. And none of those users ever convert.

That’s what Chitmark is built to catch. In three calls you can:

verify: Get an allow, challenge, or deny decision on any costly action in <50ms. Signup, trial, API key, top-up, or anything else. Server-side, with no browser required. The goal is to stop abuse without blindly denying good customers.

feedback: Tell us what happened later: credit burn, conversion, chargeback, etc. Those outcomes feed back into the system and improve the next decision.

challenge: When we're unsure, escalate. Proof of work, payment pre-auth, OTP, or whatever fits your product. Cheap for a real user, expensive for a farm. Fail to challenge, never to allow.

You get 10,000 free verify events every month, no credit card required.

The playground and site are in the links above.

Would love your feedback, especially if you've dealt with free-credit or trial abuse yourself. Thanks for checking out Chitmark ✌️
