add AI/ML API node

### Feature Idea

Hi!

I'm Sergey from the Integrations team over at [AI/ML API](https://aimlapi.com/), a startup with 150K+ users, providing over 300 AI models in one place

Your project looks dope, so we'd like to have a native integration with it. A lot of users in the community actively request it, too. We already got integrations with Langflow, Agno, and AutoGPT - so our integrations team is pretty seasoned :)

Say you're interested, and we'll test the compatibility, update the code/docs to include us, create a PR and add a tutorial on using ComfyUI nodes of AI/ML API to our docs
