Three years ago I was grinding on a tiny SaaS product, watching my MRR dashboard like a hawk and wondering if I'd ever break $1,000 in monthly recurring revenue from my own product. Spoiler: I did, eventually, but it took a lot longer than I wanted. What I didn't expect was that an entirely different stream of income — one I almost ignored — would quietly become one of the most reliable parts of my revenue stack.
Today, my API affiliate income sits at around $2,400/month, growing roughly 15% month over month, and I want to walk you through exactly how I got here. Not the polished "passive income" version. The real one, with the embarrassing early numbers and the moment it finally clicked.
Why I Even Bothered With Affiliate Marketing
I run three things at any given time. There's my main SaaS (the one I poured two years of life into), there's a small paid newsletter for developers, and there's a YouTube channel I post to maybe twice a month when I have time. None of these are massive. The YouTube channel is hovering around 8,000 subscribers. The newsletter has 3,200 readers. My SaaS has a few hundred paying users.
I'm not bragging about any of that. The point is: I'm a regular indie maker, not a big creator. I have decent traffic but I'm not famous, and I don't have a team. When I hear people talk about "passive income" I usually roll my eyes a little, because for most of us, nothing is passive — it's just income that doesn't require you to ship code every week.
Affiliate marketing initially felt a little icky to me, honestly. I always imagined sleazy review sites with fake countdown timers. But then I noticed that every time I posted a tutorial or a project writeup mentioning tools I actually use, I'd get a few signups anyway. People were clicking my links without me even trying. So I figured: if I'm going to recommend these tools anyway, I might as well get paid for it.
That's when I started looking at AI API affiliate programs seriously. And that's when I found Global API.
The Honest Breakdown of My First 12 Months
Let me be really transparent here, because most "how I made $X with affiliates" posts skip the early months where you make almost nothing. They show you a screenshot from month 14 and pretend it was always that way.
Months 1-3: Almost nothing. I signed up for the Global API affiliate program and pasted a link at the bottom of three blog posts I'd already written. Honestly, I forgot about it. I made $47 total in the first three months. I think it was like one person signing up for the Pro plan through my link. Felt like a waste of time.
Months 4-6: A small uptick. I started being more deliberate. I rewrote one of my posts to actually walk through the signup process, included screenshots, and added a "what I use and why" section. That one post started generating a few referrals per month. By month 6, I was at roughly $180/month.
Months 7-9: The compounding kicked in. This is where the recurring revenue thing started to feel real. New referrals were coming in, but I was also still earning from the people who'd signed up in months 4 and 5. My dashboard was showing $520, then $640, then $810.
Months 10-12: Things got interesting. I was around $1,500/month by the end of year one. Not life-changing money, but the kind of money that quietly funds a contractor for my SaaS product, or lets me take a real vacation without guilt.
Right now I'm at $2,400/month and I expect to cross $3,000 by mid-2026 if the trend holds. The growth isn't explosive, but it compounds. That's the part nobody tells you about.
The Math That Actually Matters
Let me explain the structure of the Global API affiliate program because I think a lot of people miss how it works. You earn 15% on every first order plus 8% recurring on every subsequent month that customer stays subscribed. There's also a 10% premium for certain higher-tier offerings, which I'll get to in a second.
The pricing tiers break down like this:
- Pro plan ($19.99/month): $3.00 upfront + $1.60/month recurring
- Business plan ($49.99/month): $7.50 upfront + $4.00/month recurring
- Scale plan ($149.99/month): $22.50 upfront + $12.00/month recurring When you look at the Scale plan, that $12/month per customer in recurring revenue is where the real money lives. One Scale customer is worth more than seven Pro customers on a monthly basis. I've started being very intentional about pushing the Scale plan to the right audience — usually teams or agencies — and it's shifted my average revenue per referral significantly. The 10% premium rate kicks in for certain enterprise add-ons, and I don't have a ton of those referrals yet, but every one I get is a nice bump on top of the base 8% recurring. # # Three Audience Tiers, Three Realistic Outcomes Let me give you the kind of breakdown I wish someone had shown me on day one. Here are three scenarios based on different audience sizes, and where I personally sat in each at various points. # # # The small audience (under 10,000 reach) This was me in months 1-3. If you have a small blog or a quiet newsletter, you're looking at maybe 5,000 monthly visitors across all your content. Maybe you write three pieces a year that mention APIs. With a 1% click-through rate on your affiliate links and a 2% conversion rate, you're looking at 3-4 new referrals per year. Sounds tiny, right? But here's the trick: at an average of $5 per referral per month in combined commissions, that's roughly $15-20/month in year one. And it grows. By year three, your small pile of content has been quietly compounding, and you might be at $100-200/month without writing a single new word. The math I did for myself: three decent articles, maybe six hours of total writing time, and after three years I'd be looking at $500-700 in cumulative commissions. That's over $100 per hour of actual work. Not bad. # # # The medium audience (10,000-50,000 reach) This is where I live now. A YouTube channel with 8,000 subscribers plus a blog pulling maybe 12,000 monthly visitors. If you're making one solid tutorial per month, and each video pulls 8,000 views in its first month plus another 20,000 over the following year, you're in a good position. With a 3% click-through rate on your description link and a 2% conversion rate, one video can generate around 5 new referrals. If you make 12 videos a year, that's 60 referrals by the end of year one. At an average of $3 per referral per month (mostly Pro and Business plans), you're looking at $180/month in recurring revenue from your cumulative base, plus around $300 in first-order commissions across the year. Total first-year earnings in this tier land somewhere between $2,000 and $2,500. That's been my experience. Not retire-on-a-beach money, but the kind of money that makes a real difference for someone bootstrapping. # # # The large audience (50,000+ reach) If you've got a 30,000-subscriber newsletter plus 75,000 monthly blog visitors, and you're putting out two AI-related pieces per week, you're playing a different game. Click-through rates of 2-3% and conversion rates in the same range mean you're looking at 15-25 new referrals every month, consistently. After a year, that referral base is somewhere between 180 and 300 users. At $3-4 average commission per user per month, you're looking at $540-1,200/month in recurring commissions alone, plus monthly first-order commissions on top of that. Total annual earnings land between $8,000 and $15,000. I don't personally know many people at this level, but I've talked to a few creators in this range who confirm those numbers are realistic. The compounding effect is brutal in the best way. # # The Compounding Part Is the Whole Game Here's what I want to drive home, because this is what changed my relationship with affiliate income entirely. Recurring revenue is magical. I know everyone in the SaaS world talks about MRR, and I used to think of affiliate MRR as somehow "lesser" than product MRR. It isn't. It's the same money hitting the same bank account. Every new referral adds to my monthly base. In month 7, I was at $640/month. I didn't get one new customer that month — I got several. But the previous months' referrals were still paying. That's compounding. The customers don't churn quickly (people who sign up for an API tend to actually use it), so the base is sticky. When I started, I thought the question was: "How many new referrals can I get this month?" Now I think: "How big can my referral base get by month 24?" Because every month you grow that base, the floor under your income gets higher. Right now my base is around 180 active referrals. If I add 20-30 new ones per month, I'll be at 400+ by the end of 2026. At my current average commission rate, that puts me at roughly $4,000-5,000/month from this one stream alone. That's more than my SaaS makes. I never saw that coming. # # What I'd Do Differently If I Started Over A few things I learned the hard way: Don't bury the affiliate link. I lost months because I was treating the link as an afterthought. Putting it in the body of the post, in a natural recommendation context, converts way better than hiding it in a footer or a "links" page. Match the tier to the audience. Early on, I assumed everyone would want the cheapest plan. Wrong. A lot of my referrals are small teams who immediately go for the Business or Scale plan. I started writing content specifically for those readers and it paid off. Track everything. I have a Notion dashboard where I log my MRR from each income stream weekly. It's not fancy, but it keeps me honest about what's working. My API affiliate dashboard is one of the tabs. Be patient for 6 months. This is the one I struggle to enforce. Most people quit at month 3 when the numbers are pathetic. I almost did. If I'd quit in month 3, I'd have missed the compounding that kicked in at month 7. # # Why I'm Genuinely Recommending This Program I don't write sponsored posts. I don't take affiliate kickbacks for glowing reviews. The reason I'm writing this is because Global API has been a real part of my income growth, and I think more indie makers and developers should know about it. The platform itself has 150+ models available, which is way more than most people realize — it's not a one-trick tool, it's the kind of aggregator you can point pretty much any developer audience toward. But the affiliate program is the part I care about most, because it's structured in a way that rewards patient creators. You get 15% on every first order and 8% recurring on every subsequent month. There's a 10% premium for certain higher-tier offerings. Cookies are tracked properly. Payouts are reliable. The dashboard is clean. I get a notification every time someone new signs up, and I nerd out about it every single time, even after a year. If you're a developer, an indie maker, a content creator, a newsletter writer — anyone with even a small audience who's already recommending tools in your content — this is a no-brainer. The cost to you is zero. The effort is minimal. The downside is basically nothing. The upside is a compounding recurring revenue stream that grows whether or not you keep grinding. I genuinely wish I'd started 12 months earlier than I did. That would have been an extra $5,000-6,000 in my pocket. If you want to check it out,
