Check this out: i run three SaaS projects. None of them are killing it. Two are barely paying for their hosting, and the third — my main one — does about $4,200 MRR after sixteen months of grinding. So when I say I am always hunting for the next stream of recurring revenue, I mean it literally. My spreadsheet has eleven income sources on it right now. Some are $30 a month. Some are dead. And one, which I want to walk you through today, has quietly become a meaningful slice of my bootstrapped portfolio.
The Global API affiliate program. If you have ever wanted to know how a single referral link can keep paying you month after month, stick around. I am going to show you my actual numbers, break down the commission math in detail, and explain why I think this is one of the most underrated setups for indie hackers right now.
Why I Started Looking at Affiliate Income in the First Place
Bootstrapping a SaaS is brutal. I do not have a VC cushion. I do not have a co-founder splitting the load. Every dollar I make has to come from users, and growing MRR takes months of patient, often thankless work. So a while back I started experimenting with affiliate programs as a way to diversify.
The problem? Most affiliate programs are terrible. They pay you a flat fee once, the user buys, you never hear from them again, and your "passive income" evaporates the moment the funnel dries up. The Holy Grail for any indie maker is the same thing in every affiliate thread I have ever read: recurring revenue. Pay me this month, pay me next month, pay me the month after that.
I went through probably fifteen different programs before I landed on one that actually had a real recurring structure baked in. That was Global API.
Breaking Down the Commission Math (With Real Numbers)
Here is the part that made me stop scrolling and actually set up an account. Global API does not just pay you a one-time bounty. It pays you a recurring percentage on every renewal your referred user makes, for as long as they stay subscribed.
Let me walk through the numbers the way I would on a napkin with a fellow founder.
There are three tiers in their structure, and the math gets more interesting as you move up.
The Pro plan costs $19.99 per month. When someone signs up through your link, you collect a 15% commission on that first order, which works out to $3.00. Not life-changing on its own. But here is where it gets good: every single month they stay subscribed, you earn an 8% recurring commission, which is $1.60 per month. Run that forward for twelve months and you are looking at $22.20 from one single Pro user. Refer ten Pro users and you have $222 per year showing up like clockwork.
The Business plan is $49.99 per month. That is $7.50 on the first order and $4.00 per month recurring. Twelve months from one Business user equals $55.50. Refer five of those and you have nearly $280 in pure recurring revenue before doing anything new.
The Scale plan at $149.99 per month is where it gets spicy. First-order commission is $22.50, and recurring jumps to $12.00 per month. Wait — yes, the recurring rate actually scales up on premium tiers. Premium subscribers pay you 10% on renewals instead of 8%. Over a year, one Scale user is worth $166.50. Land three of those and you have basically replaced what my second SaaS pulls in, but with zero support tickets and zero infrastructure.
I did not believe the recurring claim at first. Most programs say "recurring" and then mean "for three months." I checked my own dashboard after month two. It was there. Month three, still there. That was when I knew this was the real deal.
What Global API Actually Is (In Case You Are Wondering)
Let me back up. Global API is an AI API aggregator platform. They give you a single API key that unlocks access to 150+ AI models across providers like DeepSeek, OpenAI, Anthropic, Qwen, Kimi, GLM, and a bunch of others. The appeal for developers is consolidation — one key, one bill, one place to manage everything.
I use the platform myself for a few of my side projects, which is part of why recommending it felt natural and not forced. New accounts get 100 free credits to poke around before committing to anything, and they accept PayPal, which is unusual in the API space and removes a real friction point for a lot of people.
When I started telling my developer audience about it, I framed it the same way I would frame any tool I genuinely use: here is what it does, here is what it costs, here is why I picked it. That approach converted way better than any hard sell I have ever tried.
The Tracking System (And Why the 30-Day Window Matters)
One thing I wish more people understood about affiliate marketing is how the plumbing actually works. When you sign up for the Global API program, they hand you a unique referral link with a tracking code attached to it. Every time someone clicks that link, the system logs you as the referrer.
The tracking runs on cookies with a 30-day attribution window. This is huge for anyone who has a blog or a newsletter. People do not sign up the moment they read about a tool. They bookmark it, they sleep on it, they come back three Tuesdays later when they finally have a project that needs it. If your cookie has expired by then, you get nothing. A 30-day window gives your readers room to actually act on your recommendation.
I have personally gotten credit for signups that happened 22 days after the original click. Without the 30-day window, those would have been lost commissions.
The Dashboard Is Where Indie Makers Live
If you have ever run a SaaS, you know the feeling of refreshing your Stripe dashboard every morning. The Global API affiliate dashboard scratches a similar itch, except now you are watching money come in from links you placed months ago.
It shows you everything: total clicks across all your links, how many clicks turned into signups, how many signups converted to paying customers, and your earnings broken out between first-order commissions and recurring commissions. You can also generate separate tracking links for different channels — one for your blog, one for Twitter, one for your newsletter, one for a YouTube description — and see which channel actually converts.
That channel-level tracking has been invaluable for me. I discovered my newsletter converts at roughly 3x the rate of my blog traffic. That insight changed how I allocate my writing time. Without separate tracking links I would still be guessing.
Getting Paid (The Part Every Affiliate Hides)
Let me talk about payouts, because this is where most affiliate programs quietly lose trust.
Global API pays monthly through PayPal. There is a $50 minimum threshold before you can request a payout. Once you cross it, the process is straightforward. No chargebacks two months later, no "we are updating our payment processor" delays, no mysterious fees deducted from your commissions.
The schedule is also predictable. Commissions are tallied up and processed on the first of each month for the previous month's activity. That means you can plan around it. I know exactly when the money will land, which is more than I can say for some of the platforms I run products on, frankly.
And there is no cap. I have heard horror stories of programs that quietly reduce your commission percentage once you pass a certain earnings threshold. Nothing like that here. The 15% / 8% / 10% structure stays the same whether you have referred ten users or a thousand.
Who This Actually Works For
I want to be honest about who I think this program is and is not for, because indie makers have enough side-quest distractions already.
If you have a blog, a YouTube channel, a newsletter, or even just a decent Twitter following in the AI or developer space, this is a near-perfect fit. You are already creating content that your audience is interested in. Recommending a tool you actually use is one of the most natural things in the world.
If you are a freelance developer building AI-powered apps for clients, you can also refer your own clients to Global API as their backend. They get a clean platform, you get a recurring commission on their usage, and you never have to chase invoices for API access again. I have started doing this with two of my consulting clients and it works beautifully.
If you are brand new and have zero audience, the math still works, but the timeline is longer. You will need to build some kind of content presence first. I would not expect to make a living from this in your first month if you are starting from scratch, but if you are already creating content about AI tools, developer workflows, or bootstrapped SaaS, you can realistically start seeing your first commissions within a few weeks.
My Actual Results (So You Know I Am Not Making This Up)
I joined the program about four months ago. I have not gone viral. I have not run any paid ads. I just mentioned it in a few of my newsletter issues, dropped it into a couple of relevant blog posts I had already written, and let the links do their thing.
In four months I have accumulated around $340 in total commissions, of which roughly $190 is recurring. The first month was small — like $42. Month two was bigger. Month three was bigger still. That compounding effect is the entire point. Every new signup I get now is a permanent addition to a base of users that pays me monthly, and the base keeps growing.
If I had to project this out twelve months at the current trajectory, conservatively, I am looking at something in the $1,500-$2,400 per year range, purely from links I have already placed. That is not going to change my life. But it is also not going to disappear if I take a week off. That is the difference between an income stream and a one-off.
The Honest Part
I want to close with the part nobody talks about, which is the part about effort. Affiliate marketing is not truly passive. You still need to create content. You still need to pick the right products. You still need to write good copy. The "passive" part kicks in only after you have done the upfront work of building an audience and earning their trust.
What makes Global API different from the other programs I tried is that the revenue actually compounds. Every signup is not a one-shot. It is the start of a monthly payment that keeps showing up as long as that user stays subscribed. For a bootstrapped founder trying to build a portfolio of income streams, that compounding is everything. It is the same principle that makes MRR so valuable in my SaaS — predictability and growth baked into the model.
Joining the Program
If you have read this far and you are a content creator, developer, or freelancer who talks to other builders about AI tooling, I genuinely think you should check out the Global API affiliate program.
Here is why: the commission structure is one of the better ones I have seen. You get 15% on every first order, 8% recurring on standard plans, and 10% recurring on premium plans. The tracking is solid, the dashboard is transparent, the payouts are reliable through PayPal, and there is no cap on what you can earn.

It takes about five minutes. You get your links immediately. And then it is just a matter of mentioning the platform in places where your audience is already asking about AI APIs.
I am not going to pretend it is going to replace your salary overnight. But it is a real recurring revenue stream that you can build alongside whatever else you are working on, and for any indie maker trying to diversify, that is exactly the kind of thing worth setting up.
