SSL Labs APIs

SSL Labs APIs expose the complete SSL/TLS server testing functionality in a programmatic fashion, allowing for scheduled and bulk assessment. We are making the APIs available to encourage site operators to regularly test their server configuration.

We are also maintaining ssllabs-scan, an open source command-line scanning tool that doubles as the reference API client.

SSL Labs APIs are free to use, with restrictions. For the detailed license, please read our terms and conditions.
