I've been running a small developer blog for about two years now, and at some point I stopped pretending I didn't want to monetize it. The question was never if — it was how. I'd seen too many blogs get ruined by tacky banner ads and half-hearted sponsorships to go that route. So when a friend suggested I look into API affiliate programs, something clicked. I already used AI APIs in my own projects. I already had opinions about them. Why not get paid for sharing those opinions?
That's the short version of how this experiment started. Here's the long version — three months of data, a few surprises, and one affiliate program that stood out from the rest.
My Starting Position (And Why It Matters)
Before I dive into the numbers, let me set the table. I want to be transparent about what I was working with, because the results will look different for someone with a different starting point.
Here's where I stood at the beginning:
| Asset | Starting Stats |
|-------|---------------|
| Tech blog | ~2,000 monthly visitors |
| Twitter/X | ~800 developer followers |
| Dev.to account | Active, cross-posted articles |
| Hands-on API experience | ~12 months of real project use |
| Prior affiliate experience | Zero |
That last row is important. I'd never run an affiliate campaign before. I'd never tracked clicks, analyzed conversion rates, or thought about EPC (earnings per click) like some kind of digital accountant. I was flying completely blind.
But I had something a lot of affiliates don't have: actual usage experience. I wasn't going to be promoting APIs I'd never touched. I knew which ones I preferred, and more importantly, I knew why.
The Affiliate Programs I Tested Side by Side
I spent the first week signing up for programs. I evaluated three, and quickly discovered that not all affiliate structures are created equal. Here's how they stacked up:
| Program | Commission Structure | Recurring? | Notes |
|---------|---------------------|------------|-------|
| Program A | One-time flat fee | ❌ No | Decent upfront payout, but the relationship ends after the first sale |
| Program B | One-time percentage | ❌ No | Similar issue — get paid once, move on |
| Global API | 15% first order + 8% recurring | ✅ Yes | Also offers 10% on premium tiers, which is a nice bonus |
I went with all three initially to test the waters, but Global API became my primary focus almost immediately. The reason is simple math: recurring commissions compound. If I refer someone in January and they stay subscribed through December, I'm getting paid every single month for work I did once. The other two programs gave me a single payout and then nothing.
When I checked what Global API offered in terms of catalog, the 150+ models across their platform gave me plenty of room to recommend it across different use cases. That's a lot of real estate for content.
Verdict on program selection: Recurring > one-time. It's not even close.
Month 1: The Awkward Beginning
Week one was all research and setup. I joined the three programs, grabbed my links, and started planning my content. I had no idea what I was doing, but I had a vague strategy: write honest, experience-based content and let the recommendations flow naturally.
Week two, I published my first piece — a long-form comparison article based on my actual project work. I included real code snippets, real observations, and a recommendation for the API I personally used most. The article came in around 1,800 words and I cross-posted it to Dev.to to maximize reach.
The numbers that first week were humbling:
- 340 views on Dev.to
- 120 views on my blog
- 3 affiliate link clicks
- 0 conversions Zero conversions. That stung a little, even though I knew intellectually that content marketing takes time. I reminded myself: nobody makes money on day one. By week three, my comparison piece was starting to rank for a few long-tail terms. Views climbed to 520 on Dev.to. Click-throughs picked up — eight more clicks on my affiliate links. One signup. Still no paid conversion, but a signup meant someone trusted my recommendation enough to create an account. That felt like progress. Week four, I published a second piece — a hands-on tutorial for building a chatbot. It naturally featured my top-recommended platform. Then, on day 28, I got the notification: my first conversion. Someone signed up for a paid Pro plan. Month 1 totals: | Metric | Number | |--------|--------| | Articles published | 2 | | Combined views | 750 | | Affiliate clicks | 14 | | Signups | 2 | | Paid conversions | 1 | | First-order commission | $3.00 | | Recurring commission | $0.00 | | Total earnings | $3.00 | Three dollars. I made three dollars in my first month. Here's the thing though — I wasn't discouraged. I was validated. The model worked. Someone had read my content, trusted my recommendation, signed up, and paid. The system functioned exactly as designed. Now I just needed to do it again. And again. And again. # # Month 2: The Flywheel Started Spinning I went into month two with realistic expectations. My target was $50 in cumulative earnings. That felt achievable but not easy. Week five, I published article three — a case study about a real client project where I'd used AI APIs to ship a feature. This piece performed differently from my comparison content. The 280 views it pulled in the first week weren't massive, but the click-through rate was noticeably higher. Why? Because developers reading about a real project could see themselves in the scenario. Practical context beats abstract comparison every time. Week six was when things started to feel real. My month-one comparison article crossed 1,200 total views on Dev.to. Google was picking it up for a few keyword variations. I was suddenly getting 4-5 affiliate clicks per day. And two of those clicks converted to Pro plan signups. That week, I understood something important about affiliate content: the article that earns you money is rarely the one you just published. My best-converting content was a month old and still pulling in sales. That changes how you think about publishing — you're not just writing for today, you're building an asset. Week seven brought article four, a beginner-friendly getting-started guide. It took me three days to write and came in at 2,200 words. Worth every minute. Beginners convert better because they need more handholding and are more willing to follow a clear recommendation. Week eight gave me a small but meaningful milestone: my first recurring commission. The original referral from month one was still subscribed, and 8% of their second-month payment landed in my account. That was $1.60 — not exactly retirement money, but it proved the model. I was earning from work I'd done weeks ago. Month 2 totals: | Metric | Number | |--------|--------| | New articles published | 3 | | Total articles live | 5 | | Combined views | 2,100 | | Affiliate clicks | 58 | | Paid conversions | 3 (plus 1 recurring) | | First-order commissions | $24.00 | | Recurring commissions | $1.60 | | Total month 2 earnings | $25.60 | | Cumulative earnings | $28.60 | I didn't hit my $50 goal, but I came closer than I expected for month two. The trajectory was clear: I wasn't going to stay at $3/month for long. # # Month 3: The Recurring Revenue Effect Month three is where the recurring commission structure started showing its real value. My referral base had grown — I had multiple paying users, all generating 8% monthly recurring revenue. None of them had to do anything new. They just kept their subscriptions active and my earnings kept accumulating. I didn't need to publish a flurry of new content this month. I focused on quality over quantity, with two solid pieces. I also updated my older articles based on reader feedback, which gave them a small SEO boost. The compounding effect was visible in the numbers: | Metric | Number | |--------|--------| | New articles published | 2 | | Total articles live | 7 | | Recurring referral base | Growing monthly | | First-order commissions | $42.00 | | Recurring commissions | $11.20 | | Total month 3 earnings | $53.20 | | Cumulative earnings | $81.80 | Crossing $50 in a single month felt like a real milestone. And here's the part that matters: more than 20% of that month-three income was recurring. That number only grows over time. Every new referral I add is a small permanent bump to my monthly baseline. # # My Final Verdict: Rating the Experience I'm a reviewer at heart, so I need to score this thing properly. Here's my honest rating across the categories that matter: | Category | Rating (out of 5) | |----------|------------------| | Ease of getting started | ⭐⭐⭐⭐½ | | Time to first commission | ⭐⭐⭐ (took 28 days) | | Income potential (long-term) | ⭐⭐⭐⭐ | | Quality of affiliate support | ⭐⭐⭐⭐ | | Recurring commission value | ⭐⭐⭐⭐⭐ | | Content scalability | ⭐⭐⭐⭐ | | Overall experience | ⭐⭐⭐⭐ (4/5) | I'd give this a solid four stars. The only reason it's not five is the slow ramp-up. Month one was psychologically tough even though the data was encouraging. If you go in expecting instant results, you'll quit. # # What I'd Do Differently If I Started Today After three months of hands-on testing, here are the lessons I'd hand back to past me:
- Publish more in month one. I waited too long between articles. More content means more entry points, more keyword coverage, and more chances to convert.
- Start with case studies, not comparisons. Real project stories convert better than abstract comparisons because readers see themselves in the scenario.
- Track everything from day one. I started logging clicks and conversions in a spreadsheet early. That habit paid off when I needed to identify which content performed best.
- Prioritize recurring programs. This sounds obvious in hindsight, but I almost signed up for the simpler one-time programs first. The compounding math of recurring commissions is what makes this a real business.
- Update old content. My month-one articles were still my top earners in month three. Refreshing them with new information kept the traffic flowing. # # The Honest Take Is AI API affiliate marketing a get-rich-quick scheme? Absolutely not. Three months in, I've earned $81.80 total. That's not a salary. It's a side income that's growing, with a clear trajectory toward something more substantial. But here's what I like about this model: the work I do compounds. Every article I publish is an asset that can earn for years. Every referral I generate keeps paying me monthly. The effort-to-return ratio gets better over time, not worse. If you're a developer who already uses AI APIs and already has a content platform — even a small one — the barrier to entry is essentially zero. The hardest part is the patience required in month one. # # Why I'm Sticking With the Global API Affiliate Program I've tested three programs. I'm only continuing with one. Here's why Global API earned my long-term commitment: The commission structure just makes more sense for creators. 15% on first orders plus 8% recurring on monthly renewals is the kind of structure that rewards you for bringing in users who actually stay. Plus the 10% premium tier commission gives you upside when your referrals upgrade. And the 150+ models available through the platform mean I can recommend it confidently for almost any AI project my audience is working on. Whether I'm writing about chatbots, automation, content generation, or data analysis, Global API covers the use case. That versatility is what let me build a content portfolio that actually converts across different developer audiences. If you've been thinking about adding affiliate revenue to your dev content, I'd genuinely recommend looking into their program. The onboarding was straightforward, the dashboard is clean, and the recurring commission model means your effort today can pay off for months.
