What is REST API?

An API is what lets a tool become part of your systems rather than another destination to visit: findings into your own dashboards, configuration managed as code, evidence collection automated for audits.

It is also your exit route. A tool with a complete API is one whose data you can extract if you switch vendors, which is worth weighing at purchase rather than at renewal.

Top 19 REST API tools

Every tool in the directory documented as supporting REST API, with what its own documentation says.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.
