  GET 'https://api.mailbloc.com/[email protected]&ip=1.12.1.12’\
  -H "Authorization: Bearer {YOUR_API_KEY}”

  Response:
  
  {"risk_level": "high", "reasons": ["disposable_email", "datacenter_ip"]} // Done!

One endpoint. Send email + IP, get clear risk level. Done in 2 minutes.

APIVoid Integration

        POST /v2/email-reputation
        POST /v2/ip-reputation  
        POST /v2/domain-reputation
        POST /v2/url-status
        // 20+ different endpoints...

        Each returns different JSON structures
        with various data points to interpret
              

Multiple APIs. Choose which to call, parse different responses. Great for security analysis, complex for signup validation.

Common Questions

Can I use APIVoid for signup validation?

Yes, but it's like using a Swiss Army knife when you just need a can opener. APIVoid's email and IP reputation APIs work fine for signup validation, but you'll need to call multiple endpoints, parse different response formats, and build your own risk scoring logic. Mailbloc does this for you.

Is APIVoid's data more comprehensive than Mailbloc's?

For threat intelligence, yes. APIVoid has 20+ APIs covering URLs, domains, SSL certificates, DNS, and more. But for signup validation specifically, both check the same core blocklists and reputation sources. The extra data in APIVoid is valuable for security analysis but overkill for signup fraud.

Why would I choose APIVoid over Mailbloc?

Choose APIVoid if you're a security analyst, SOC team, or need to integrate threat intelligence into a SIEM platform. It's designed for comprehensive security operations, not application signup validation. If you're building an app and just need to stop fake signups, Mailbloc is the better fit.

Does Mailbloc integrate with SIEMs?

No, Mailbloc is not designed for SIEM integration. It's built for real-time application signup validation. If you need SIEM integration, URL scanning, or comprehensive threat intelligence, APIVoid is the right choice.

Which has better documentation?

Both have good docs, but they serve different needs. Mailbloc's docs focus on getting signup validation working in 2 minutes. APIVoid's docs cover 20+ APIs with various use cases. For signup validation specifically, Mailbloc's docs are more focused and easier to follow.

Built for Developers, Not Security Analysts

Stop fake signups with one simple API endpoint. No complex threat intelligence dashboards, no multiple APIs, no security degree required. Forever free plan.

No credit card required • One endpoint integration • Clear risk levels
