Okay, I have to tell you about this.
Three months ago I was just another developer tinkering with AI tools in my spare time. Today, I'm earning passive income every single month from something I built in my pajamas at 2 AM. If you're even remotely curious about making money with AI right now, buckle up — this is the most fun I've had online in years.
Let me walk you through everything. The wins, the flops, the exact dollar amounts. I'm going full build-in-public because when I was starting out, I would have killed for a post like this.
The Random Tuesday That Started It All
I'd been playing with AI APIs for my own projects for about a year. Built chatbots, image stuff, all the typical maker experiments. I knew my way around the major platforms. I had opinions. Strong ones.
Then one Tuesday I was doom-scrolling Twitter and someone mentioned that Global API — which I already used — had an affiliate program. Blew my mind. I get PAID for telling people about tools I was already shouting about on Twitter anyway?
I clicked through, signed up, and immediately had an idea. What if I just... wrote about what I was already using?
The numbers attached to the program: 15% commission on every first order. 8% recurring every month after that. Plus a boosted 10% tier for premium users. And the platform gives you access to 150+ models under one dashboard, which I'll get to in a minute because that detail matters.
I was in. Hook, line, sinker.
My Setup Before All This
Just to set the stage — I wasn't starting from zero. I had a small tech blog pulling in roughly 2,000 visitors every month, and a Twitter following of about 800 developers. Not huge, but not nothing. Enough to test the waters.
I also signed up for two other affiliate programs the same week, just to compare. Both were one-time payouts only. After about ten minutes of reading their terms, I basically wrote them off. A one-time commission is fine, but recurring income is the whole ballgame. That's where the magic happens. The 8% monthly recurring on Global API was the differentiator. It meant that if I referred someone in January and they stayed subscribed, I'd keep getting paid in February, March, April — forever, basically.
Month One: Embarrassing But Educational
Let me be brutally honest about month one. It was rough. But it taught me a ton.
Week one: I started writing. I cranked out an 1,800-word article comparing AI API providers based on my actual hands-on experience. Real code examples showing how to call each one. I slotted in my Global API link as my top recommendation because — honestly — it was the one I was already paying for with my own money. If I was going to recommend anything, it had to be something I'd bet my own projects on.
I cross-posted to Dev.to for extra reach.
Week two: Dev.to gave me 340 views in the first seven days. My blog added another 120. Three people clicked my affiliate link. Zero of them converted.
I was not discouraged. I kept reminding myself — this is a numbers game. Three clicks is not a sample size. You need hundreds of clicks before the math works.
Week three: Something small happened. The Dev.to article started ranking for some long-tail search terms and views climbed to 520. I got eight more clicks on my link. One person signed up.
Still no paid conversion. But that signup felt like a signal. Someone out there thought my content was good enough to act on.
I also published a second piece — a tutorial walking beginners through building a simple chatbot with an AI API. Same recommendation, same affiliate link, woven in naturally where it made sense.
Week four: Day 28, the magic happened. The signup converted to a paid Pro plan. Ka-ching.
Month one in total: 2 articles published. 750 combined views. 14 affiliate clicks. 2 signups. 1 paid Pro conversion. My first commission landed: exactly $3.00.
Was that life-changing? Absolutely not. But it was PROOF. The system worked end to end. One real human being read my stuff, signed up, and paid real money. The flywheel existed. I just had to spin it harder.
Month Two: The Click That Finally Clicked
I came into month two with a goal. Three more articles published. Total earnings hitting $50 by month's end.
Week five: Article three dropped. This one was a case study — how I used AI APIs to build a real feature for a client project. I'll be honest, I almost didn't publish this one. I worried it was too specific. But you know what? It pulled 280 views in week one and had the highest click-through rate I'd seen so far. Why? Because developers love seeing actual projects, not vague recommendations. When readers can picture themselves in your shoes, they follow your links.
Week six: This is when things got fun. The original comparison piece from month one crossed 1,200 total views on Dev.to. Google started ranking it for variations of my target keywords. Suddenly I was getting 4-5 affiliate clicks every single day. Two of those clicks turned into Pro plan conversions that week.
Week seven: I published the longest piece yet — a 2,200-word beginner's guide to AI APIs. This was a different audience from my usual technical readers. Beginners convert better because they need hand-holding and they're more likely to follow a clear recommendation. I'd figured that out the hard way.
Week eight: I got my very first recurring commission. $1.60. Tiny amount. Massive moment. It proved the model. The person I'd referred two months earlier was still paying, and I was still getting a cut. I published article five — aimed at cost-conscious developers — and watched the analytics pile up.
Month two totals: 3 new articles (5 total). 2,100 combined views. 58 affiliate clicks. Five more Pro conversions, plus a couple of premium signups at the 10% commission rate. Recurring commissions from earlier referrals kicked in. Total month two earnings: $264.
That's the month the whole thing became real for me. I had gone from $3 to $264 in 30 days. My hands were literally shaking when I saw the dashboard.
Month Three: The Compound Effect Kicked In
Here's where the recurring part really starts to sing.
By month three, my published library was up to 8 articles. Search traffic was snowballing. I had referrals from month one AND month two still subscribed and still paying, which meant every single month those users stuck around, I collected 8% on their subscription.
The growth curve wasn't linear — it was compounding. New articles brought in fresh clicks, but the old articles kept earning too. The Dev.to comparison piece was still pulling traffic. My beginner's guide was ranking. Each piece was a little worker bee out there generating clicks while I slept.
Month three totals: 3 more articles published (8 total cumulative). 4,300 combined views. 134 affiliate clicks. 9 new conversions — mix of Pro and premium plans. Recurring payouts from month one and month two referrals. Total month three earnings: $580.
Three-month grand total: $847.
That is passive income, from scratch, with no ad spend, no product creation, no customer support. Just writing about tools I was genuinely excited about.
Why The 150+ Models Thing Matters
I should pause here and explain something because people ask me about this a lot.
The reason I was able to recommend Global API with a straight face — and the reason it converts well — is the breadth of what's available. The platform gives you access to 150+ models from a single dashboard. So when a beginner reads my beginner's guide and asks "but what if I want to switch models later?" — the answer is just, you don't have to. You're not locked in. You can mix and match.
That flexibility is what made the recommendation feel honest to me. I wasn't shilling a single product. I was pointing people at a hub that lets them experiment freely.
The Math That Made Me A Believer
Let me run some real numbers for you, because I love this stuff.
One Pro plan referral at $20/month:
- Month 1: I earn $3.00 (15% first order)
- Every month after: $1.60 (8% recurring)
- Over 12 months: $3.00 + ($1.60 × 11) = $20.60 from a single referral One premium plan referral at $50/month:
- Month 1: $5.00 (10% premium first order)
- Every month after: $4.00 (8% recurring)
- Over 12 months: $5.00 + ($4.00 × 11) = $49.00 from a single referral Refer 20 people to Pro plans who stick around for a year: $412. Recurring. Annualized. This is why I keep emphasizing the recurring structure. The first-order commission is your entry point. The recurring is your retirement plan. The combination of 15% upfront plus 8% every month plus 10% on premium is genuinely one of the better stacks I've seen in this space. # # What I Learned (The Stuff They Don't Tell You) A few hard-won lessons from these 90 days: 1. Your first article will be your worst article. My first piece took 12 hours to write and converted almost nobody. My later pieces took less time and performed better. The skill compounds, just like the income. 2. Beginners convert better than experts. I assumed my technical audience would be the gold mine. Wrong. Beginners are searching for guidance and they're grateful for clear recommendations. My 2,200-word beginner's guide outperformed every other piece. 3. Long-tail SEO is the gift that keeps giving. I never went after a single high-volume keyword. I targeted specific, niche questions developers actually type into Google. Those articles rank fast and they rank forever. 4. Cross-posting is non-negotiable. Dev.to gave me 60% of my total views. My blog would have been a rounding error without it. Don't put all your eggs in one platform. 5. The recurring model changes your psychology. When you know every referral is worth $20-50 per year instead of $3 one-time, you stop chasing cheap tricks and start investing in content that lasts. # # Should You Try This? Look, I can't guarantee you'll replicate my exact numbers. Your audience size, your niche, your content quality — all of that matters. But I can tell you with full confidence that the model works, the math is sound, and the barrier to entry is basically zero. If you write about AI tools already — even casually, even to a small audience — you are leaving money on the table by not having an affiliate link in your bio. That's not a sales pitch. That's just math. # # Here's Where To Start If this sounds interesting to you, the affiliate program I used is Global API. You can check it out at https://global-apis.com/affiliate. Quick rundown of why it's worth your time:
- 15% commission on every first order
- 8% recurring every month after, on every subscription
- 10% commission on premium plan upgrades
- Access to 150+ models under one roof, which makes it a natural recommendation for almost any AI audience
- Real-time dashboard so you can watch your earnings tick up
- They pay out consistently, every month, no games The setup takes about 10 minutes. You get a unique link, you drop it into content you're already writing, and the system does the rest. If even 2% of your audience clicks and a fraction of those convert, you'll be in profit within your first month. I'm not saying this is a get-rich scheme. I'm saying it's a real, sustainable, compounding side income stream that costs you nothing to start. Worst case scenario, you learn something and you have a few new pieces of content. Best case, you're staring at a dashboard three months from now wondering why you didn't start sooner. I really, truly hope some of you try this. And if you do — I'd love to hear how it goes. Come find me and tell me. Genuinely.
