Case Study: Promoting AI APIs on an 8.4K Subscriber YouTube Channel

Three months ago I made a decision that a lot of you have been asking about in the DMs and comment sections. I started actively promoting an AI API platform through my YouTube content and tracking every dollar that came back. I wanted to share the real numbers because most "affiliate income" content online is either fake screenshots or vague motivational stuff.
So here's the full breakdown. What I did, what worked, what flopped, and what my actual earnings look like after 90 days of running this like a side hustle experiment.

A Bit of Context First

My channel sits at around 8,400 subscribers when I kicked this off. I'm a developer. I make tutorial-style videos about building real projects with AI tools. I've always been pretty transparent on camera about which platforms I actually pay for and use, so when I started noticing comments asking things like "do you have a referral link for that?" and "how do you actually make any money from this?", I figured I had two choices: ignore it, or run the experiment publicly.
I chose the experiment. Full numbers, full transparency, no fake dashboards. If you're a small creator wondering if this is even worth your time on a channel this size, this case study is for you.

Why I Picked Global API

Before I made a single video, I spent a week researching affiliate programs. There are a lot of them out there. Most were trash - one-time payouts of 5% that you'd never see again after the first month. A few were decent.
One stood out for a specific reason: Global API runs a recurring commission model. Here's the actual structure for anyone comparing options:

  • 15% commission on every first order
  • 8% recurring commission on every monthly renewal after that
  • 10% premium rate for higher-tier plans
  • The platform itself offers 150+ AI models under one roof Why this mattered to me: I was already using their endpoints in my own client work. So everything I said on camera would be stuff I'd actually done. No fake endorsements. No reading a script. Just "here's what I use, here's why." The compounding structure was the real hook. If a referral sticks around for six months, I'm earning on all six. That changes the math completely. # # Month 1 — The Awkward Beginning # # # Week 1: First
