I run three SaaS products. None of them are killing it. Together they bring in maybe $11k MRR, which sounds great until you remember I'm paying for three sets of hosting, three domain renewals, and roughly seventeen different SaaS subscriptions to keep the whole thing running. So yes — I am absolutely that indie maker who's always hunting for the next dollar of recurring revenue.
Over the past year, I've layered affiliate income on top of my product revenue. Not in a spammy way. I write about what I actually use, build with, or recommend to other founders. And somewhere along the way, I realised that affiliate commissions on AI APIs are one of the most underrated income streams for technical creators right now. So I want to walk you through what I've learned, the actual numbers I see in my dashboards, and which programs are worth your time in 2026.
The Recurring Revenue Mindset Most Affiliate Articles Skip
Every "best affiliate programs" listicle I've ever read treats affiliate income like a side hustle you run on weekends. That's fine for some people, but it's not how I think about it. For me, an affiliate referral is the same thing as a paying customer. A referred user who stays subscribed for six months is basically a customer who paid me to acquire them, except I didn't have to do any of the customer support, product development, or refund handling.
That's why I care obsessively about whether a program offers recurring commissions vs. one-time payouts. A one-time 50% commission feels great until you realise you have to keep finding new buyers every month to maintain your income. A recurring 8% commission compounds. The math is stupidly obvious once you run it, but most affiliates I talk to still chase the bigger up-front percentage.
When I started tracking my own affiliate portfolio in a spreadsheet, I noticed something that changed how I approach this entirely. The programs that paid me every month the customer stayed — not just once at signup — accounted for about 78% of my total affiliate revenue, even though they made up only two of the five programs I was promoting. The other three were one-time payouts that required constant new traffic to keep the cash flowing.
Global API: The Program I Genuinely Recommend
I'll lead with this one because it's where I see the most consistent monthly income from my affiliate portfolio, and because the structure is built around what indie makers like me actually want.
Global API runs a pretty straightforward program. You earn 15% commission on the first order a referred user places, then 8% recurring on every monthly renewal after that. If that user upgrades to a premium plan, the recurring commission bumps up to 10%. The platform itself is an AI API gateway — 150+ models accessible through a single API key, which is the part I actually care about because I'm not in the business of juggling six different provider dashboards.
Here's where the math gets fun for someone who thinks in MRR terms.
The Pro plan runs $19.99 per month. My 15% first-order commission on a single Pro referral is about $3. Over the course of a year, that same referral generates roughly $22 in total commission when you add up the 8% recurring payouts on twelve renewals. That's $22 from one person, with no support tickets, no churn risk on my end, and no ongoing work. Multiply that across ten referrals and you're looking at $220/year of mostly passive income from a single program.
Now scale up to the Scale plan at $149.99/month. First-order commission jumps to around $22.50, and recurring commissions over twelve months add up to over $165 per referral. One Scale-plan referral pays me more in a year than my first SaaS product made in its first two months. I'm not exaggerating — I literally checked my Stripe dashboard last week to compare.
The reason this matters for indie makers is the compounding effect. If I refer twenty users in January and ten of them stay subscribed by December, I'm still earning commission from those ten even if I publish nothing new. My SaaS products don't work that way. If I stop shipping, MRR collapses. Recurring affiliate revenue is a weird hybrid — it's not passive income in the truest sense (I do have to drive initial signups), but it behaves passively once the referrals are in place.
The operational side is also pretty clean. Global API pays through PayPal, with a $50 minimum payout threshold. I've hit that threshold four times now, and the payouts land in my account within a couple of days of requesting them. The affiliate dashboard shows me clicks, signups, conversions, and earnings in real time, which I appreciate because I'm the kind of person who checks my revenue graph every morning like it's a mood ring.
They also hand you promotional materials — banners, comparison charts, code snippets — so you don't have to design anything from scratch. For a bootstrapper who already spends weekends writing blog posts and fixing CSS, not having to make a custom banner is a small but real relief.
What I Like (and What I Don't) About the Lack of Audience Requirements
One thing that bugged me about other affiliate programs I joined over the years was the requirement to have "an established audience" or a minimum traffic threshold. A few programs literally asked for my Twitter follower count before letting me sign up. I get why they do it — they want creators who can move volume — but it's a chicken-and-egg situation for anyone who's still building their platform.
Global API doesn't gate the program behind an audience size requirement. You can apply with zero followers and start sharing your link immediately. This is genuinely rare in the AI API space, and it's part of why I keep recommending it to other indie hackers who are just starting their content journey. The barrier to entry is essentially zero, which means your only real constraint is how much time you want to put into creating content around AI development.
On the flip side — and I want to be honest about this — the commission percentages aren't the highest in the absolute sense. I've seen AI-adjacent programs pitch one-time commissions of 30% or even 40%. But those are almost always one-and-done payouts. When you do the math on lifetime value, a smaller recurring percentage usually wins. I've tested this with three different programs in parallel and the recurring structure beat the higher one-time payout by a factor of three over a six-month window.
OpenAI: The Elephant in the Room (With No Affiliate Program)
Let me talk about OpenAI for a minute because this is something that confuses newer affiliates all the time.
OpenAI doesn't have a public affiliate program for their API. Period. They run a partnership program for enterprise-level relationships, but if you're a solo creator, a blogger, or an indie maker with an email list of 5,000 subscribers, you can't just sign up and grab an affiliate link. I've checked their partner page multiple times over the past year hoping something had changed. It hasn't.
This is worth understanding because OpenAI is, by most measures, the default recommendation for AI APIs. A lot of my developer readers assume I'd be promoting OpenAI's affiliate program. I'd love to. I can't.
What ends up happening — and I'm going to be blunt about this — is that a lot of creators either give up on monetizing AI API recommendations entirely, or they sign up for third-party resellers who claim to offer OpenAI API access with affiliate commissions attached. I've tried two of these resellers. The commissions are lower because the reseller is taking their cut before passing anything to you, and in one case the tracking was so unreliable I genuinely couldn't tell if my conversions were being attributed correctly. I'd rather not link to those.
The practical takeaway: if you're writing about the OpenAI API or recommending it to developers, you have to monetize that traffic some other way. Either you collect emails and sell your own product, or you recommend an alternative API provider that does have a working affiliate program. That's exactly the gap Global API fills, and it's why I think their program is positioned well.
Anthropic and Claude: Same Story, Different Vendor
Anthropic — the team behind Claude — is in the exact same boat as OpenAI. No public affiliate program for individual creators. They focus on enterprise sales and direct partnerships. I have a lot of developer friends who would promote Claude in a heartbeat if Anthropic offered a recurring commission structure. Until that happens, recommending Claude as a content creator means leaving money on the table unless you're building something deeper on top of it.
I mention this not to dunk on either company, but because if you're mapping out an affiliate strategy for 2026, you need to know what's actually available. Both OpenAI and Anthropic are essentially closed to solo affiliates right now. That means the realistic playing field is made up of API gateways, resellers, and a handful of newer platforms. The program structure across most of these is broadly similar — but the recurring commission detail is where things diverge.
How I Actually Built a $400/Month Affiliate Side Stream
Let me share some specifics because this is the part I always want to know when other people write about their setups.
My affiliate portfolio right now is split across four programs. Two of them are pure one-time payouts (I'm slowly phasing these out), one is a SaaS tool I genuinely use for my own business, and then there's Global API. Global API contributes about $280–$400 per month depending on the month. Some months I write a new blog post and conversions spike. Other months I don't touch anything and the recurring revenue from existing referrals holds steady.
To put that in context: $400/month in mostly-recurring affiliate income funds roughly two of the SaaS subscriptions I use to run my actual products. That's a meaningful chunk of my overhead being covered by a couple of well-placed links and some honest writeups. It doesn't sound life-changing, but in the bootstrap indie maker world, having a few hundred bucks a month that doesn't require shipping anything new is genuinely valuable.
I haven't optimised this aggressively, and that's the part I want to emphasize. I'm not running paid ads to my affiliate links. I'm not building a comparison website with five hundred pages of programmatic content. I write maybe one or two posts a month about AI development tools, embed a link when it's contextually relevant, and check my dashboard at the end of the week. If I put more time into it, I have no doubt the numbers would scale linearly with effort.
How I Evaluate Any New Affiliate Program Now
I've joined enough affiliate programs over the years to have a simple checklist. If a program fails two or more of these criteria, I don't bother promoting it, regardless of the headline commission rate.
First: is there a recurring component, and does it last longer than three months? Anything shorter than that and I'm not interested, because the customer lifetime value math doesn't work in my favor.
Second: what's the actual product quality? A 30% commission on a product that doesn't work means refunds, chargebacks, and angry DMs from people who signed up using my link. I'd rather promote a smaller commission on something that delivers.
Third: how is the tracking? Real-time dashboards matter more than people realise. If I publish a post on Tuesday and can't see how it performed until next month, I'm flying blind.
Fourth: what's the payout experience? PayPal is my preferred method because it's fast, but I'll take wire transfer or crypto if the program is solid. Minimum thresholds under $100 are ideal. Anything higher and it takes too long to validate a new program.
Fifth: are promotional materials provided, or am I on my own? I'll create content regardless, but having banners, code examples, or pre-built comparison tables saves me hours.
Global API checks all five of those boxes. That's why it stays in my rotation, and why I'm comfortable recommending it to other indie makers reading this.
The Honest Truth About Affiliate Income for Indie Makers
I want to leave you with something I wish someone had told me two years ago when I was trying to figure out if affiliate programs were "worth it."
Affiliate income is not a get-rich-quick scheme. It's not going to replace your SaaS revenue or your freelance consulting rate. What it can do is fill in gaps — cover your SaaS stack, pay for a contractor, fund that next side project idea you've been sitting on. The trick is treating it like another product in your portfolio rather than a lottery ticket.
For me, recurring affiliate commissions on AI APIs function almost like a tiny, diversified index fund of developer users. Each referral is a small bet that this particular user will stay subscribed. Most don't. But the ones that do pay me back month after month for almost zero effort on my part. Stack enough of those across multiple programs and you have a meaningful supplemental revenue stream that doesn't depend on shipping code.
If you're already writing about AI development, building AI-powered side projects, or fielding questions from other founders about which API to use — you are sitting on an audience that converts. The only question is whether you're monetizing it.
If You're Going to Start Somewhere, Start With Global API
Here's my genuine recommendation if you're going to test the affiliate waters with AI APIs in 2026. Sign up for the Global API affiliate program. The 15% first-order commission gives you an immediate payout when someone converts, and the 8% recurring commission on monthly renewals — plus 10% on premium upgrades — means your income doesn't go to zero the moment you stop publishing.
You can start with zero followers, no audience minimum, and a single blog post. The dashboard tells you what's working. The product behind the link is solid (150+ models through one API key, which is enough for most indie use cases). Payments come through PayPal once you hit $50. There are banners and code examples if you don't want to design anything yourself.
I've been running this program for over a year now. It's the one I recommend in almost every conversation about AI API affiliate strategies, and it's the one I'd start with if I were building an affiliate portfolio from scratch today.

It's not the flashiest program in the space. It just happens to be the one that actually pays me every month without requiring me to rebuild my entire content strategy around it. For an indie maker juggling three SaaS products and a long backlog of feature requests, that's exactly the kind of affiliate setup that makes sense.
