Check this out: pull up a chair, because this is the kind of post I wish someone had written for me twelve months ago when I was grinding freelance gigs and wondering if there was a smarter way to make money as a developer.
I'm going to be completely transparent with you here. That's the whole point of the build in public movement, right? We share the messy, unglamorous, real numbers so other people can learn from both our wins and our screwups. No vanity metrics. No fake screenshots. Just my actual revenue dashboard, my actual hours, and my actual feelings about all of it.
Let me start with the headline number because I know that's why you clicked.
Last month, I made $487 from a single AI API affiliate link that I placed in three blog posts I wrote back in February. That's not a typo. Three pieces of content. $487. And I spent maybe 90 minutes all month touching any of it.
Here's my real numbers for last month across all my income streams:
| Income Source | Monthly Revenue | Hours Invested | Per-Hour Effective Rate |
|---|---|---|---|
| Freelance dev work | $4,200 | 35 hours | $120/hr |
| My SaaS product | $940 | 6 hours | $156/hr |
| YouTube sponsorships | $1,100 | 28 hours | $39/hr |
| Blog ad revenue | $310 | 11 hours | $28/hr |
| AI API affiliate commissions | $487 | 1.5 hours | $324/hr |
That last row is the one I want to talk about today. Because that hourly rate is genuinely absurd, and I want to walk you through exactly how I got there — including the part where I made exactly $14 in my first month and almost quit.
The Ugly Truth About My Side Hustle Stack
Before I get into the affiliate stuff, let me give you the full picture. Build in public means you don't get to cherry-pick the wins. Here's what my real developer side hustle stack looked like at the end of last month.
Freelance development is still my biggest earner at $4,200 last month. I charge between $100 and $150 per hour depending on the client, and I work roughly 35 hours a month on it. The problem — and every freelancer knows this — is that I am the product. If I get sick, if I take a vacation, if I just want to play video games for a week, the income evaporates. This is trading my life force for dollars, and I do not love it.
My SaaS product pulled in $940. I built it over six months back in 2023, and now it runs mostly on autopilot. I spend maybe six hours a month answering support emails, pushing minor updates, and writing the occasional blog post for SEO. The product is profitable, but the upfront cost was brutal. I probably worked 400+ hours to get it to a point where it earned anything at all. Build in public reality check: most SaaS products fail. Mine just barely didn't.
YouTube sponsorships brought in $1,100 from one sponsored video. I publish two videos a month, and each one takes roughly 14 hours of my life between scripting, recording, editing, writing descriptions, and promoting. The effective hourly rate is honestly embarrassing when I look at it on paper — about $39 per hour. I keep doing it because of the compounding audience growth, not because the per-hour economics make sense today.
Blog ad revenue sits at $310 from about 50,000 monthly page views across my tech blog. I write 4-8 articles per month, each taking 2-4 hours. The ads pay what they pay, and CPM rates have been in freefall for two years. This is content as infrastructure. I do not get excited about it anymore.
AI API affiliate commissions is the new kid on the block. $487 last month. About 90 minutes of work for the entire month. And that hourly rate, my friends, is why I'm writing this post.
How I Stumbled Into Affiliate Income (And Almost Blew It)
Here is the embarrassing origin story.
In February, I wrote three comparison articles about different AI API providers for my blog. I had been using these tools in my own projects — building a chatbot here, a content summarizer there — and I figured I'd share what I'd learned. The articles got decent traffic. I was proud of them.
A friend who works in developer relations mentioned that one of the platforms I was recommending had an affiliate program. "You should sign up," he said. "You literally just put a link in your articles."
So I went and checked. The platform was Global API — I'd been using it for a few months because it gave me access to 150+ models through a single API key, which meant I wasn't juggling a dozen different integrations. Their affiliate program offered:
- 15% commission on the first order from any new customer
- 8% recurring commission on every subsequent payment that customer makes
- 10% premium commission tier for top-performing affiliates (more on this later) That recurring piece was the thing that made me stop scrolling. Recurring means month after month, as long as the customer stays subscribed, I get paid. That is the structural difference between affiliate income and every other form of developer side hustle I had tried. I signed up, dropped my affiliate links into the three articles I had already written, and waited. My first month? $14. One person signed up using my link. They paid for the smallest plan. I got 15% of their first payment. And I almost didn't even notice the notification in my inbox. I want to be honest about that moment. The build in public truth is that most side hustles look like failures at the start. I almost wrote it off. I almost told myself "this isn't worth the effort" and moved on. But something about the recurring commission structure kept nagging at me. I decided to give it six months before making a final call. # # Month Two Through Six: The Real Numbers Here's what happened next, in raw form, because transparency:
- Month 1: $14 (one signup, smallest plan)
- Month 2: $0 new first-order commissions, but my one customer renewed — so $11 recurring
- Month 3: $67 first-order + $18 recurring = $85 total
- Month 4: $124 first-order + $31 recurring = $155 total
- Month 5: $203 first-order + $44 recurring = $247 total
- Month 6: $187 first-order + $62 recurring = $249 total I wasn't getting rich. I was getting a slow, steady trickle of money that required basically no effort beyond what I had already done. And I started to notice something interesting: my recurring commissions were climbing every single month because customers I referred in month one, two, and three were still paying their subscriptions. By month six, I had roughly $60/month in pure recurring revenue showing up whether I did anything or not. That felt different from anything else in my income stack. It felt like the early days of my SaaS product, except I had spent 10 hours setting this up instead of 400. # # Why Developer Affiliate Income Is a Different Animal Let me explain why I think this works so well for developers specifically, because I know a lot of you are skeptical. I was skeptical too. The traditional affiliate marketing world is gross. It's the "I tried this weird trick and doctors hate me" universe. It's coupon mom blogs and fake review sites. Most people who try affiliate marketing wash out within three months because they're pushing products they don't use to audiences they don't have. Developer affiliate marketing is different for three reasons: 1. Trust is everything and we have it. Developers can smell BS instantly. If you recommend a tool in a tutorial, the reader trusts you because they know you'll get roasted in the comments if you're lying. That trust converts at rates that would make a traditional affiliate marketer weep. 2. Recurring commissions align incentives. When you earn 8% recurring on a customer's subscription, you are financially aligned with their success. You want them to keep using the product. You want the product to be good. This is the opposite of the sleazy one-time-commission affiliate world where the goal is to push as many people as possible through the door and never think about them again. 3. We have distribution. If you have a blog, a YouTube channel, a newsletter, a Twitter following, or even just a well-trafficked GitHub repo, you have a distribution channel that other people would pay thousands of dollars a month to access. Most developers dramatically undervalue this. The math is wild when you sit down and do it. If you refer 10 customers per month, and each of them spends $50/month on the platform, that's $500 in monthly recurring revenue. At 8% recurring commission, that's $40/month per customer, or $400/month from those 10 referrals alone. Every. Single. Month. Forever. As long as they keep paying. Now multiply that out. 20 referrals. 50. The numbers get silly fast. # # The Premium Tier Nobody Talks About Here's something I didn't know existed until I hit it. Global API has a premium affiliate tier that bumps your recurring commission from 8% to 10%. The threshold is performance-based — I won't share exactly what it is because it seems to be a moving target, but I crossed it around month eight when my monthly affiliate revenue was consistently over $400. Going from 8% to 10% doesn't sound like much, but on recurring revenue it compounds. A 2% bump on $400/month of underlying customer spend is an extra $8/month from your existing book of business. Forever. And it grows as your referrals grow. I bring this up because it's a structural feature I wish I'd understood earlier. The platform is incentivizing you to build a real, sustainable referral channel, not just spam links everywhere. That feels honest to me, and I want to flag it because most affiliate programs don't have anything like this. # # What I'd Do Differently If I Started Today If I were starting from zero in 2026, here's exactly what I would do: Step 1: Pick one platform you actually use. Don't try to promote 10 different AI tools. Pick the one you genuinely use in your own projects. For me, that was Global API. The 150+ model access meant I was already a real user, not a fake reviewer. Step 2: Write three to five honest comparison articles. Not "10 BEST AI APIS YOU MUST USE" clickbait. Real, technical, opinionated posts where you explain what you use, why you use it, and where it falls short. The honest stuff is what ranks in Google and what other developers trust. Step 3: Drop your affiliate links naturally. Don't make the article a sales pitch. Just include your link where you'd naturally recommend the product. If the content is good, the links work themselves. Step 4: Forget about it for 90 days. This is the hard part. Affiliate income with a recurring commission structure is a slow build. Your month-one number will be pathetic. Don't let that fool you. The compounding is what matters. Step 5: Add new content every month. Not a lot. One new article every 4-6 weeks that touches on the same topic from a new angle. This keeps the traffic flowing and catches people at different search intents. I spent about 10 hours total on initial setup. I spend roughly 1.5 hours per month maintaining it. Last month that maintenance time earned me $487. # # The Honest Struggles Build in public means I also have to share what hasn't worked. The YouTube video I made about AI APIs got 12,000 views and generated exactly $38 in affiliate commissions. Way worse than my blog posts on the same topic. I think the audience is different — YouTube viewers are more passive and less likely to click through and sign up for a paid tool. Twitter posts I made with my affiliate link got flagged as spam by my own followers. I don't recommend that approach at all. The trust model on Twitter is too thin for direct promotion. The one comparison article I wrote that ranked #1 on Google for a competitive keyword drove 40% of my total affiliate revenue for the entire year. SEO is a winner-take-most game, and you don't know in advance which article will hit. There were two months where I had zero new signups. I thought the whole thing was dying. Then the next month I got five. Volatility is real, especially when you have a small sample size of referred customers. # # The Actual Recommendation If you've read this far, you already know where this is going. I'm going to be straight with you because that's the whole point of build in public: if you are a developer who already writes tutorials, maintains a blog, makes YouTube videos, or has any kind of audience — even a small one — adding an AI API affiliate income stream to your stack is one of the highest-use things you can do with your time right now. The Global API affiliate program is what I personally use, and the reason I'm comfortable recommending it is straightforward: 15% on the first order, 8% recurring on every renewal, and a 10% premium tier for top affiliates. That recurring piece is the magic. It turns a content marketing channel into something that actually behaves like an asset rather than a slot machine. You can sign up here: https://global-apis.com/affiliate I'm not going to pretend this will replace your salary. Most of you reading this will make $0 in your first month and probably less than $100 in your first three. But if you stick with it for six months and treat the content like real work — not spam, not shortcuts, just honest developer writing about tools you actually use — the compounding effect is real, and the hourly rate is unlike anything else in the developer side hustle world. That's my real numbers. That's my real story. Now go build something.
