Build Secure Applications with Threat Intelligence
Modern applications need security built in from the start. Whether you're building a web application, mobile app, or backend service, integrating threat intelligence helps protect your users from malicious content. Our APIs make it easy to check URLs before redirecting users, verify domain reputation before displaying content, or block malicious IPs before they can exploit your systems. A few lines of code can dramatically improve your application's security posture.
Developer-First API Design
We built our API with developers in mind: - **RESTful Design**: Standard REST conventions that work exactly as you'd expect - **Consistent Responses**: Predictable JSON response formats across all endpoints - **Comprehensive Errors**: Clear error messages with actionable guidance - **Versioned API**: Breaking changes only in major versions, with long deprecation windows - **Rate Limit Headers**: Know your quota status with every response - **Request IDs**: Every request gets a unique ID for debugging and support No surprises, no gotchas - just a clean API that's easy to integrate.
Official SDKs and Client Libraries
Don't write boilerplate - use our official SDKs: - **Python SDK**: Fully typed with async support, available on PyPI - **Node.js SDK**: TypeScript definitions included, works with CommonJS and ESM - **Go SDK**: Idiomatic Go with context support - **Rust SDK**: Safe, fast, and memory-efficient All SDKs include automatic retry logic, rate limit handling, and comprehensive documentation. They're open source on GitHub, so you can see exactly how they work.
Free Tier for Development and Testing
Get started without commitment: - **1,000 Free Requests/Month**: Enough for development, testing, and small-scale production use - **No Credit Card Required**: Sign up with just an email address - **Full API Access**: The free tier includes all endpoints, not a limited subset - **Generous Rate Limits**: 10 requests/second - plenty for development workflows - **Forever Free**: Not a trial - the free tier doesn't expire When you're ready to scale, paid plans start at $49/month with flexible usage-based pricing.
