These tools expose an API, so you can call them from your own code rather than working through their interface. This is the list to start from if you are building AI into a product, a script or an automation.

What to check before you choose
Having an API is the start of the question rather than the end of it. Rate limits, pricing per call, whether there is a sandbox to develop against, and whether your inputs are retained or used for training all vary enormously, and all of them shape whether a tool is viable at scale. Official API documentation is the only reliable source for those details, and it changes often — treat this list as a way to find the candidates, then verify the specifics with the vendor before you build.
