Integration guides
Working code for the framework you use. Each guide covers where the check goes, what the timeout should be, and what happens when the API is down, not only the happy path.

How do I add fraud protection to an AI-built app?
Add Maskbreak to an AI-built app with a secret-free prompt, server-side decisions and a checklist that verifies your deployed site.
What is the simplest genuinely free signup-protection API for EU users?
Compare free signup-protection options, understand Maskbreak’s 1,000 hourly checks, and review EU data handling before protecting your SaaS.

Move from observation to enforcement with stable cohorts, a real review path, clear release gates and a rollback plan that restores customer journeys.
When a fraud check times out: design the fallback
A timeout is missing evidence, not an allow verdict. Choose fallbacks per action, bound retries, and keep sensitive operations behind their authorization checks.

Login is where everyone looks, but accounts are also taken over through password reset, MFA enrolment, contact changes and session refresh. One helper, six call sites.

A screening decorator for Flask that survives gunicorn forking, ad blockers and a dead upstream — with the session-reuse and timeout details.
Spring Boot Fraud Detection Without a Java SDK
A RestClient bean, an interceptor, and the three Spring details that decide whether this survives production: pooling, timeouts, and failing open.
Blocking Fake Signups in Supabase When You Do Not Own the Signup
auth.signUp runs on Supabase infrastructure, not yours — so the fraud check has to go somewhere else. Three places it can go, and which one to pick.

Two WordPress hooks, one HTTP call, and the caching and checkout details that decide whether it works — including the form that empties your token.
ASP.NET Core Fraud Detection Without a .NET SDK
A typed HttpClient, an endpoint filter, and the two .NET details that decide whether this works in production: handler lifetime and the JSON property names.
Bot Detection in a Cloudflare Worker: What the Edge Can and Cannot See
A Worker sees the IP, ASN and TLS fingerprint before your origin wakes up — and never sees the device. Where each check belongs, and how to fail open.
FastAPI Fraud Detection: One Dependency, Failing Open
A screening dependency you would actually deploy: per-route strictness, the threadpool detail that keeps the event loop free, and a fail-open path.
Rails Fraud Detection Without a Ruby SDK
No Ruby SDK, and for a one-endpoint API that is fine. A Net::HTTP client, a controller concern, per-action strictness, and a fail-open path.
Go Fraud Detection Middleware, Without an SDK
No Go SDK needed for a one-endpoint API. A net/http middleware with a real timeout, fail-open behaviour and a circuit breaker, in about seventy lines.
Django Fraud Detection: Middleware That Fails Open
A production-shaped Django integration for VPN, proxy and antidetect detection: per-path strictness, DRF wiring, and the failure handling most examples omit.
Express Fraud Detection Middleware That Fails Open
