# From $3 to My First Real MRR: My 90-Day AI API Affiliate Build Log > Source: > Published: 2026-06-26 15:00:41+00:00 Hey, I'm an indie maker. I run three small SaaS products, a tiny newsletter, and I keep trying to layer new income streams on top without burning out.

No investors, no cofounders, no team. Just me, a laptop, and an unreasonable tolerance for staring at Stripe dashboards at 11pm. I also have a small developer blog that pulls in around 2,000 monthly visitors and a Twitter following of about 800 developers I've accumulated over the years by sharing builds and shipping in public. When I decided to add affiliate marketing to the mix, I wasn't trying to replace my SaaS income. I wanted a stream that didn't come with a support inbox attached. Something that could grow while I slept, ideally — a compounding asset rather than another hourly trade. I burned a long weekend researching AI API affiliate programs. Most of them were forgettable — flat one-time payouts that evaporate the moment the customer signs up. But three stood out as worth testing:
