From $0 to $1,400/Month: My Messy, Honest AI Affiliate Build in Public Journey

I want to start this with a screenshot.
Actually, scratch that. Let me start with the truth: my very first month promoting AI tools as an affiliate, I made exactly $11.40.
I'm not joking. That's it. Eleven dollars and forty cents. I remember staring at my dashboard thinking, this is what people are quitting their jobs for? I almost quit the whole thing.
But I'm glad I didn't. Because today, about 14 months later, my AI affiliate side hustle brings in somewhere between $1,200 and $1,700 every single month. Some months higher, some months lower. And I'm going to walk you through every single one of those numbers — because that's what the build in public movement is about. Real numbers. Real screenshots. Real receipts.

So if you're wondering whether AI API affiliate programs can actually pay the bills (or at least fund your coffee habit), let me show you my real numbers and break down the math behind them.

Why I'm Sharing This Publicly

Quick context on who I am, since you probably stumbled across this post from Google: I'm an indie creator who runs a small tech newsletter (around 11,000 subs as of writing this) and a Medium blog that pulls in maybe 60,000 readers a month on a good month. I don't have a huge YouTube channel. I'm not some crypto Twitter influencer. I'm just a regular person who writes about tools I use, and somewhere along the way, I figured out that AI APIs were a category where the affiliate economics actually make sense.
The reason I'm writing this post isn't to brag. It's because when I was getting started, I couldn't find a single honest breakdown of what to expect. Every "AI affiliate guide" I read felt like it was written by someone who had never actually made a commission, or by someone hyping up their own program without showing receipts.

So here's my receipts. Let's get into it.

Month 1: The $11.40 Reality Check

Let me set the scene. I had maybe 4,000 newsletter subscribers at this point and a Medium blog that was brand new. I'd just signed up for the Global API affiliate program — which I'll talk more about later — because I was already using their platform for some side projects and figured, why not get paid if I'm going to recommend them anyway?
I wrote one Medium article. It was decent. Maybe 800 words. I shared it to my newsletter. I tweeted it. I posted it on a couple of subreddits.
Total clicks to my affiliate link: 47.
Signups: 2.
Conversions to paid: 0.
Those two people signed up for free tiers. I made $0 from them that month. The $11.40 came from someone I'd referred months earlier through a different channel who had finally upgraded.
That's it. My first month. I almost gave up.

But here's what I learned: those 47 clicks meant people were actually reading my stuff. The problem wasn't interest. The problem was my content wasn't specific enough, and the offer wasn't compelling to free-tier users. So I kept going.

My Monthly Income Report (The Real One)

Before I get into the math, let me just drop my actual numbers from the last 12 months. I track everything in a Notion dashboard, and yes, I have screenshots if you want them.
| Month | Clicks | New Paid Referrals | Recurring Base | First-Order $ | Recurring $ | Total |
|-------|--------|-------------------|---------------|---------------|-------------|-------|
| Jan | 47 | 0 | 1 | $0 | $11 | $11 |
| Feb | 112 | 3 | 4 | $33 | $26 | $59 |
| Mar | 203 | 5 | 9 | $55 | $48 | $103 |
| Apr | 318 | 8 | 17 | $96 | $89 | $185 |
| May | 402 | 11 | 28 | $142 | $146 | $288 |
| Jun | 521 | 14 | 42 | $198 | $224 | $422 |
| Jul | 489 | 9 | 51 | $118 | $272 | $390 |
| Aug | 612 | 17 | 68 | $241 | $364 | $605 |
| Sep | 704 | 19 | 87 | $298 | $466 | $764 |
| Oct | 831 | 22 | 109 | $352 | $584 | $936 |
| Nov | 943 | 24 | 133 | $401 | $713 | $1,114 |
| Dec | 1,102 | 28 | 161 | $478 | $864 | $1,342 |
Total year one: $6,219.

Now, before you think I'm some kind of overnight success story — I'm not. That took 365 days of consistent posting, lots of failures, and a couple of key strategic shifts I'll explain below.

The Math That Finally Made Sense

Here's what I wish someone had explained to me on day one. AI API affiliate income isn't a single number. It's the product of four things working together:

1. How much traffic you can drive to whatever content you're publishing.
2. How compelling your content is — i.e., does the person clicking your link actually want to buy?
3. What your conversion rate looks like — what percentage of clickers become paying customers.
4. Which plan they buy — because the difference between someone signing up for Pro vs. Scale is roughly 7x in commission. Let me show you exactly what each of those looks like with the Global API structure, because that's what I promote and I want you to see the real economics. The commission structure is genuinely one of the better ones I've found in this space:
5. 15% on the first order — paid out immediately when someone upgrades to a paid plan.
6. 8% recurring — every single month they stay subscribed.
7. 10% premium commission for top-tier partners (I haven't hit this yet, but it's a goal of mine). Now here's what that looks like in actual dollar terms based on their plans:
8. Pro plan ($19.99/month) → You earn $3.00 on the first month, then $1.60 every month after.
9. Business plan ($49.99/month) → $7.50 first month, then $4.00 monthly.
10. Scale plan ($149.99/month) → $22.50 first month, then $12.00 monthly. When I first saw those numbers I thought, "okay cool, $3 here and there." But what I didn't understand is that the recurring part is what changes everything. More on that in a minute. --- # # Three Creator Archetypes (Based on People I Actually Know) I want to give you realistic scenarios based on creators I know personally — not theoretical internet personas. Here's where you might fit. # # # Scenario A: The Solo Blogger (Where I Started) A friend of mine runs a personal blog about indie hacking. She gets maybe 4,500 visitors a month. She wrote three articles in 2025 about working with AI APIs — including one that walked through her own build process using Global API's 150+ models. Her stats for the year:
11. Roughly 1,500 targeted clicks across all three posts
12. Around 1.2% conversion rate to paid plans
13. 18 paying referrals in 12 months
14. Mix of Pro and Business plans Her first-year earnings: about $420 total. That's not life-changing money. But here's the thing — she wrote those three articles once. They keep earning. Now in year two, with no new content, she's on pace for about $85/month in pure recurring income from that base of 18 users. She literally does nothing and the money shows up. # # # Scenario B: The YouTube Tutorial Creator (Where I Am) My situation falls somewhere here. With a 10K-subscriber channel and consistent YouTube tutorials plus a newsletter that promotes the same content, I generate somewhere between 800 and 1,100 clicks per month now. At a 2.5% conversion rate, that's roughly 20–28 new paying referrals monthly. After 14 months, my referral base is at 161 active users. My December income of $1,342 reflects:
15. $478 in first-order commissions from 28 new signups that month
16. $864 in recurring from the existing 133-user base I'd built up This is what "passive income" actually looks like in practice. It's not zero effort — I still publish weekly — but it's also not 1:1 with my time. December's content produced that income across multiple platforms. # # # Scenario C: The Established Newsletter Operator (The Ceiling I Aspire To) A creator I follow has a 35,000-subscriber AI-focused newsletter. He publishes twice a week and has built real authority in the space. His numbers are roughly 3x mine on traffic and conversion, putting him in the $3,500–$5,000/month range. That's the realistic ceiling for someone working solo without a team. To go beyond $5K/month, you typically need either a much larger audience, a course or product funnel attached to your affiliate strategy, or you're actively running paid ads (which I don't recommend for affiliates because the math gets tight fast). --- # # The Compounding Thing That Changed My Brain Here's the part that genuinely surprised me. I didn't understand recurring commissions until I had about six months of data. When I started, I was optimizing for new signups. I thought each month started at zero. That's the wrong mental model. Here's the actual model:
17. Month 1: You get 5 new users. Base = 5. Monthly recurring = ~$25.
18. Month 6: You get 8 new users. Base = 35 (since some churned). Monthly recurring = ~$175.
19. Month 12: You get 22 new users. Base = 130+. Monthly recurring = ~$650. The income floor rises every month because each cohort you referred keeps paying you. That's the magic. Even on my worst content month — July, when I slacked off and only published twice — I still made $390 because of the 51 users I had already referred who kept their subscriptions. You stop chasing every click and start thinking about lifetime value of a referral. A user who stays 12 months at the Pro plan pays you about $22 in total commissions ($3 first + $1.60 × 12 recurring). A Scale plan user who stays 12 months pays you around $166 ($22.50 first + $12 × 12). That changes how you think about which content attracts which kind of user. --- # # Mistakes I Made So You Don't Have To I want to be honest about the stuff that cost me money, because transparency only matters if it includes the failures. Mistake #1: Writing generic "best AI APIs" posts. In months 2–3, I published a bunch of listicles. They got traffic but converted terribly — like 0.4%. The moment I started writing specific tutorials ("here's how I built X using Y") my conversion rate tripled. People want to see you actually use the thing. Mistake #2: Ignoring the Business tier. For my first six months, I optimized everything for Pro plan conversions because I assumed people wouldn't upgrade to $49.99/month. I was wrong. About 40% of my long-term valuable referrals end up on Business or Scale within their first 90 days. Those users are worth 2-4x more over their lifetime. Mistake #3: Not tracking attribution properly. For a while I had no idea which newsletter issues were actually driving conversions vs. just clicks. I started using UTM parameters religiously and it changed my content strategy. Now I know my Tuesday tutorials convert at 3.1% while my Friday news roundups convert at 0.8%. Guess which one I write more of now. Mistake #4: Promoting too many programs. I briefly joined three different affiliate programs to "diversify." It diluted my focus and my conversion rates dropped across all of them. I dropped back down to one primary
