01In plain English
An API lets one piece of software send requests to another and get answers back. With a tool's API, a developer or an automation platform can create, read and change things in it without anyone using the app itself.
02Why it matters when you are choosing
An API is what lets a tool fit into the rest of your stack: pushing results into your CRM, running jobs in bulk, or building your own features on top. Without one, you are limited to the integrations the vendor chose to build.
03What to check
Check whether the API is on your plan or costs extra, what the rate limits are, and whether the docs are public. A public, well-documented API is a good sign in itself.
04The tools
269 of the 365 tools we checked have an API. Each one is checked against the vendor's own pages. A tool missing from this list may not have been checked yet, which is not the same as a no.
