Your report covers 8 key areas of your API's security posture.
We evaluate CORS configuration: allowed origins, methods, headers, and credentials.
We verify the HTTPS connection works correctly and uses secure protocols.
We detect authentication mechanisms like Bearer tokens and WWW-Authenticate headers.
We check rate limiting headers (X-RateLimit-*) and Retry-After for abuse protection.
We detect information leakage in Server, X-Powered-By headers and verbose error messages.
We evaluate cookie security flags: HttpOnly, Secure, and SameSite.
We verify Content-Type consistency and secure error handling.

Frequently Asked Questions
An API security analysis evaluates 8 areas: HTTP security headers (HSTS, CSP, X-Frame-Options), CORS configuration, SSL/TLS, authentication mechanisms (Bearer, API keys), rate limiting, information leakage (Server, X-Powered-By, stack traces), cookie security, and error response handling.
Yes, IQ Source's API security scanner is 100% free with no strings attached. Enter your API URL and receive a complete PDF report with scores across 8 categories and prioritized recommendations directly in your email.
An API security analysis takes 10 to 30 seconds. IQ Source's scanner makes real HTTP requests (GET and OPTIONS) to the API endpoint to obtain accurate results about its security configuration.
No, an API security scanner like IQ Source's only makes standard GET and OPTIONS requests — the same ones any web browser would make. It doesn't execute attacks, penetration tests, or send malicious payloads to the server.
Yes, scanning an API with an online scanner is safe when the scanner only makes standard HTTP requests. IQ Source's scanner transmits your information encrypted, only uses your email to send the report, and doesn't store analysis results.
