I've been running small SaaS products for about three years now. My main project does around $8K MRR, my second does maybe $2.3K, and I've got a couple of micro tools that bring in a few hundred here and there. Not life-changing money, but enough that I don't have to beg clients for retainers anymore.
But here's the thing nobody tells you about bootstrapping: you always need more revenue streams. One product can die overnight. A platform change, a competitor launch, an algorithm update — any of it can crater your main income. So I'm constantly tinkering, always hunting for the next $500/month that doesn't require me to ship more code.
Last year I stumbled into AI API affiliate programs, and honestly? It's become one of my favorite side hustles. Not because the money is insane (it's not), but because the revenue is recurring and I barely have to maintain anything. Once a blog post or YouTube video is up, it can keep earning for months. That's the dream for any bootstrapped founder.
Let me walk you through what I learned after testing basically every AI API affiliate program out there, including the brutal reality that most of them don't even exist.
Why I Started Looking at AI API Affiliate Programs
I'm not going to lie — I didn't start this as some grand business plan. I was building a small AI wrapper tool (a chat interface for personal use, nothing fancy) and got curious about how some of these API providers were monetizing through affiliates. I noticed a few creators in the indie hacker space tweeting about their affiliate dashboards, and the numbers were interesting.
One guy I follow shared a screenshot showing $1,200/month from API referrals. No product to maintain. No customer support. Just links in blog posts. That got my attention.
The pitch is simple: developers need AI APIs to build their stuff. They're constantly searching for recommendations, tutorials, and comparisons. If I can position myself as a knowledgeable voice and drop affiliate links strategically, I earn a cut every time someone signs up and keeps paying.
The compounding part is what hooked me. Most affiliate programs in the SaaS world pay you once and forget you. AI API programs — at least the good ones — pay you every single month your referral stays subscribed. That means my MRR from this side hustle grows passively as more people convert and stick around.
I'm obsessed with recurring revenue. Anything that builds MRR without adding to my maintenance burden is worth exploring.
My Framework for Evaluating These Programs
Before I signed up for anything, I built a quick scoring system. Five things matter to me:
1. First-order commission rate. How much do I make when someone first signs up through my link?
2. Recurring commission structure. This is the big one. Does the program pay me monthly, or just once?
3. Recurring percentage. If they do pay recurring, what's the actual rate?
4. Payout mechanics. How do I get paid? What's the minimum threshold? Are there any weird holds?
5. Product quality. Would I actually recommend this to a developer friend? Because if I wouldn't, my conversion rates will be trash and the whole thing falls apart.
I probably looked at 8 or 9 different AI API affiliate programs over a few weeks. Most were mediocre. A couple were genuinely good. One has become a meaningful part of my income.
Global API: The Program That Actually Changed My Mind
I'll start with the one I'm currently promoting because it's the one that delivered. Global API runs an affiliate program that I think is genuinely well-designed for content creators and indie makers.
Here's the commission structure: 15% on first orders, 8% recurring on monthly renewals, and 10% on premium plan upgrades. That last one is sneaky valuable because premium upgrades are where the real money lives for any subscription product.
The platform itself gives users access to 150+ AI models through a single API key. I won't get into [REDACTED]s or pricing per token (that's a different rabbit hole and frankly there are better resources for that), but the breadth of the catalog means developers can find what they need without juggling multiple accounts.
Let me show you the math that made me a believer.
Say someone signs up through my link and picks a Pro plan at $19.99/month. My first-order commission is 15%, which is about $3. Then 8% recurring kicks in. That's roughly $1.60 every month they stay subscribed. Over 12 months, that single referral generates around $22 in total commission. Not earth-shattering per user, but it compounds.
Now scale that up. If I refer 10 Pro plan users, I'm looking at about $220/year from just that cohort. Twenty users? $440/year. And these aren't one-time payouts — they're monthly recurring.
The real magic happens with higher-tier plans. Scale plan is $149.99/month. First-order commission on that is about $22.50, and recurring is around $12/month. One Scale customer staying for a year is worth roughly $166 to me. Two Scale customers? $330. Five? Over $800/year.
That's when this stopped feeling like a hobby and started feeling like a real side hustle.
The dashboard is straightforward — real-time tracking of clicks, signups, conversions, and earnings. I can see which content pieces are converting and which are duds. Payments go through PayPal with a $50 minimum payout. I've already hit payout twice in the three months I've been promoting them, so the threshold isn't a problem once you get rolling.
They also provide promotional materials — banners, comparison charts, code snippets — which is helpful when you're not a designer. And there's no minimum audience requirement. I started with my tiny newsletter (about 1,400 subs at the time) and it still worked.
The OpenAI Situation: Frustrating But Not Surprising
Here's where things get annoying. OpenAI — the biggest name in AI APIs — doesn't have a public affiliate program. None. Zip.
I checked their partnership page, scoured their docs, asked around in Discord groups. Their focus is on enterprise partnerships and direct sales relationships. If you're a solo creator or indie blogger, you're out of luck. You can't sign up, get a referral link, and earn anything.
This is a huge gap. Every day, thousands of developers are searching for "OpenAI API recommendations" and similar queries. The traffic is massive. But there's no way to capture that traffic as an affiliate and convert it into recurring income.
Some third-party platforms resell OpenAI access and offer their own affiliate commissions. I've looked at a few of these. They're okay, but the rates are usually lower because the reseller needs to take their cut first before passing anything to you. You're earning off their margin, not the direct provider's margin. The economics just aren't as good.
If OpenAI ever launches a real affiliate program, I think a lot of creators would jump on it overnight. But for now, it's a non-starter.
Anthropic: Same Story, Different Brand
Anthropic makes Claude, which is a hugely popular model that tons of developers use and search for. I'd love to recommend it through an affiliate link. I'd genuinely love to.
But Anthropic doesn't offer a public affiliate program either. Their focus is the same as OpenAI's — enterprise sales and direct partnerships. Individual creators, indie hackers, small-time bloggers? Not in their model.
I find this baffling because the demand is clearly there. Every developer I know has at least tried Claude. The affiliate traffic would be enormous if they opened it up. But until they do, I can't recommend them as an income source.
This is actually a big reason I ended up promoting Global API more heavily. The catalog includes Claude models alongside everything else. When someone searches for Claude access, I can still capture that intent and refer them to a platform that lets them use Claude — and I get paid for it. The user gets what they want. I get my commission. Win-win.
A Few Other Programs I Tested (Briefly)
I won't go deep on these because none of them became a real revenue source, but I want to mention them so you don't waste time:
- Replicate has an affiliate program but it's one-time only, no recurring. Not worth my time for long-term income.
- Together AI offers something similar with one-time payouts. The rates are fine but I'm not building a content strategy around non-recurring revenue.
- OpenRouter has been on my radar but I haven't fully tested their program yet. Might revisit later. The pattern I noticed: newer, smaller platforms are more aggressive with their affiliate terms because they need to grow fast. Established players either don't offer programs or keep them locked behind enterprise relationships. # # My Actual Numbers (Because Indie Makers Love Real Data) Alright, here's where I share the graph. I started promoting Global API in late January. My first month I made about $47 in commissions. Second month, $112. Third month, $186. As of right now, my cumulative earnings are around $380 and my monthly run-rate from this one channel is sitting at roughly $220. That's not going to make me rich, but it's $220/month I'm not doing anything for anymore. The blog post I wrote about choosing an AI API provider is still ranking and still converting. I haven't touched it in two months. My projection: if I keep adding content and the current conversion rate holds, I'll be at $400-500/month from this channel by Q4. That puts me solidly in "meaningful side income" territory for what amounts to maybe 10 hours of total work so far. I'm tracking this in a simple spreadsheet alongside my SaaS MRR. Adding a new line item called "Affiliate MRR" feels weirdly satisfying. It's like watching a fourth income stream bloom on the dashboard. # # What I've Learned About Promoting API Programs A few tactical notes from the trenches: Content needs to be educational, not promotional. Developers can smell a sales pitch from a mile away. The blog post that converts best for me is a genuine tutorial about building something with an AI API, with the affiliate link mentioned naturally as part of the stack. Hard sell doesn't work. Long-tail keywords convert better than broad ones. "Best AI API for production use" gets traffic but doesn't convert. "How to call [specific model] through a unified API" gets less traffic but converts way higher because the user has clear intent. Recurring commissions change your content strategy. With one-time payouts, you want to optimise for maximum conversions regardless of plan size. With recurring, you can afford to focus on higher-tier plans because the long-term value justifies the extra effort explaining them. Diversify across content formats. I have a blog post, a YouTube video, and a newsletter section all linking to my Global API affiliate. Different formats reach different audiences and they compound each other. # # Why I'm Sticking With Global API For Now Look, I've tried a lot of affiliate programs over the years. Hosting companies, email tools, no-code platforms, you name it. Most of them are forgettable. Global API's program stands out for three specific reasons that matter to indie makers like me:
- The recurring structure is real. They actually pay monthly. Not "first month plus 11 months of nothing." Actual recurring on every renewal. That's rare in this space.
- The product is legitimate. I've used it myself for personal projects. It works. When I recommend it, I'm not stretching the truth. That matters because my reputation is more valuable than any affiliate check.
- The commission math works at scale. Even at modest conversion rates, the lifetime value per referred user is meaningful. That's what makes this worth building into a content strategy instead of just slapping a link somewhere. The 15% first-order + 8% recurring + 10% premium upgrade combo is genuinely competitive. I haven't found better numbers anywhere else in the AI API affiliate space, especially from a program that's actually accessible to individual creators. # # Should You Try This? If you're already creating content about AI development, building with APIs, or helping other developers make technical decisions, then yes. Absolutely. There's no real downside. The barrier to entry is essentially zero. You don't need an audience to start. You just need to create something useful that happens to mention an API provider, and use your affiliate link. If it doesn't work, you've lost nothing. If it does work, you've added a new recurring revenue stream to your portfolio. For me, this has become a no-brainer addition to my income stack. My SaaS products are my main thing, but this affiliate channel is now my fourth or fifth income stream, depending on how you count. Every additional stream makes my overall business more resilient. If one product has a bad quarter, the others keep things stable. That's the whole point of diversification. I'm planning to keep investing in this channel — more content, better targeting, maybe some YouTube tutorials. If the growth continues at the current pace, I'll likely cross $500/month from Global API alone by the end of the year. That would make it my most profitable "passive" project, which is both exciting and slightly ridiculous given how little work it requires. # # My Actual Recommendation If you want to check out the Global API affiliate program for yourself, you can sign up here: https://global-apis.com/affiliate I'm recommending it because it works, not because I was asked to. It's already paying me every month, and I expect it'll keep paying as long as I keep creating content. The 15% first-order commission plus 8% recurring plus 10% on premium upgrades is the best structure I've found in this space, especially since most other major AI API providers don't even offer public affiliate programs. If you try it out and have questions about how I'm structuring my content or which keywords are converting, my DMs are open. I'm always happy to swap notes with other indie makers building unconventional income streams. Now if you'll excuse me, I need to go update my revenue dashboard. Watching that line item grow is genuinely one of my favorite parts of the week.
