IPQS alternative for developer-first fraud checks

Use RequestGuard when you want IP, email, domain, device, CAPTCHA, and user-risk checks in one developer-first decision API.

Many teams start with individual reputation checks: IP score here, email score there, domain data somewhere else. That works until the product needs a single answer.

RequestGuard is built around the decision your backend needs: allow, challenge, review, or block.

Why developers choose one decision API

Developer-first fraud checks should be easy to wire into product flows. The endpoint should accept the context you already have and return a response that can drive application behavior.

const assessment = await requestGuard.assess({
  ip,
  email,
  domain,
  userAgent,
  event: "signup",
  sessionId,
});

What gets combined

RequestGuard can combine:

  • IP reputation and connection risk.
  • VPN, proxy, Tor, and datacenter signals.
  • Email and domain risk.
  • Device and session context.
  • CAPTCHA fallback decisions.
  • User and behavior metadata.

When IPQS may still fit

If your team wants a broad reputation vendor for many separate lookup categories, IPQS may fit your workflow.

If your team wants an EU-made, SDK-first decision layer that developers can add to signup, checkout, forms, and API access, RequestGuard is the sharper fit.

The point is not more lookup data. The point is a cleaner action at the moment abuse creates cost.
