What tools are you using to keep API costs down when building AI side projects?
Hello guys!
I’ve been trying to build out a few automated AI workflows to generate online income, but API costs keep eating into my profit margins way faster than expected. Right now, my stack uses Make.com for webhooks, OpenRouter to switch to cheaper models and TeamoRouter as the main gateway to handle network layer caching so I'm not paying full price every time an agent resends long context windows.
It’s working decently so far to keep token spend under control, but I feel like my stack could be a lot cleaner and more efficient. For anyone else leveraging AI tools or agents for side income, what tools or infrastructure are you using to keep your operating costs as low as possible?
