Honestly, i'm going to be brutally transparent with you here because that's the whole point of build in public. For the past twelve months, I've been running an AI API reseller business on the side, and I've been documenting every dollar earned, every mistake made, and every late-night realization along the way. No vanity metrics. No "I made $50,000 in 30 days" nonsense. Just the real stuff.
If you're a developer who's tired of trading time for money and keeps seeing the same recycled "passive income" advice everywhere, this one's for you. I'm going to walk you through exactly how I got started, what the income actually looked like month by month, the tools I used, the niche I picked, and why I think this model is still wildly underrated heading into 2026.
Let's get into it.
Lesson 1: Stop Overthinking. Just Pick a Backend and Move.
The single biggest thing that slowed me down in the beginning was analysis paralysis. I'd spend entire weekends reading comparison posts, testing different platforms, and convincing myself I needed to find the "perfect" setup before I could talk to a single customer. That was a mistake, and it cost me probably three months of progress.
Eventually, I landed on Global API as my backend provider. The reason was simple: they give me access to 150+ models through a single API key. I didn't have to juggle five different vendor relationships, manage separate billing systems, or debug five different authentication setups. One dashboard, one integration, one invoice. For a one-person operation like mine, that consolidation alone saved me probably ten hours a week.
Here's the part most people gloss over: their affiliate program. They pay 15% on every first order a customer places through my link, and then 8% recurring on every renewal after that. Plus there's a 10% premium tier for higher-volume partners, which I'll explain more about later. For someone starting from scratch with zero ad budget, that's a really forgiving structure because you're getting paid even before your customers become profitable for you.
The point isn't that Global API is the only option out there. The point is that I spent way too long "researching" when I should have been selling. Pick something solid, integrate it, and start talking to people. You can optimise later.
Lesson 2: My Real Month-by-Month Income (The Ugly Truth)
Okay, here's the part everyone actually wants to see. These are my actual numbers from the first twelve months. I'm sharing them publicly because if nobody shares the bad months, new people get a completely warped view of what's possible.
Month 1: $0. I didn't make a single dollar. I spent the entire month setting up my landing page, writing documentation, and getting my first integration working. I had one sign-up but they churned before paying anything.
Month 2: $47. A friend from college needed AI features for a small SaaS project and agreed to route through my reseller setup. My commission on their first invoice was $47. I was ecstatic. I screenshot that dashboard and sent it to my partner like I'd just won the lottery.
Month 3: $124. Added two more small customers. Both were indie developers who'd heard about my service through a Reddit post I wrote at 2 a.m. The recurring piece hadn't kicked in yet, so this was all first-order commissions.
Month 4: $89. This is where the "build in public" mentality really gets tested. My biggest customer paused their account because they were waiting on funding. Revenue dropped. I had to remind myself that this was normal and not a sign that the whole thing was doomed.
Month 5: $203. Recurring commissions started flowing. The customers from months two and three renewed, and that 8% kicked in automatically. I added two new customers from a single blog post that unexpectedly went semi-viral on Hacker News.
Month 6: $412. This was the first month I felt like this might actually be a real business. The recurring revenue compounded with new sign-ups, and I crossed $400 for the first time. I celebrated with a slightly nicer coffee than usual.
Month 7-9: averaging $580/month. Steady growth. I wasn't doing much marketing at this point. Most new customers came from word-of-mouth referrals and a few YouTube tutorials I'd made.
Month 10: $891. I hit the volume threshold to negotiate custom reseller terms, which bumped me into that 10% premium tier. My effective commission rate on a chunk of my customer base went from 8% to a much healthier number. Suddenly the math started looking really different.
Month 11-12: averaging $1,150/month. I'm writing this in month 13 now, and my trailing 90-day average is just over $1,200.
So the total for year one? About $7,800. Not life-changing money. But here's the thing: I built this in my spare time, didn't quit my day job, and the recurring portion is now growing on its own. In month 12 alone, roughly 65% of my revenue came from renewals. That's the part people don't talk about enough. Recurring revenue is a completely different game than one-time sales.
Lesson 3: Niches Are Everything. I Failed Twice Before It Clicked.
I want to save you the pain of my first two attempts because they were both expensive lessons.
**Attempt
1: Generic "AI API for everyone."** I launched a site that was basically a thin wrapper around the underlying provider. No specific audience, no tailored experience, no clear reason to choose me over going direct. I got almost zero traction because I was competing on a playing field where the platform itself had infinitely more resources. Don't do this.
**Attempt
2: Marketing copy generation.** I thought every business needed AI-written ad copy. Turns out, the existing tools in that space were already incredibly mature, with massive venture funding behind them. I was a solo operator trying to outcompete well-funded startups. Bad match.
**Attempt
3 (the one that worked):** I pivoted to serving independent developers and small technical teams who wanted to add AI features to their apps but found the existing platforms overwhelming. I built a simplified onboarding flow, wrote documentation that assumed zero prior AI experience, and offered support via a simple chat widget. My pitch became: "You focus on building your product. I'll handle the AI plumbing."
That positioning worked because I wasn't trying to beat the platforms on price or features. I was selling simplicity and guidance, which are things a massive platform simply can't do well. The underlying API calls are commoditized. The wrapper, the docs, the human support, the onboarding experience — that's where the value lives.
If I had to give one piece of advice on niche selection, it would be this: pick an audience you already understand. My background is in web development, so selling to other developers felt natural. I knew what their pain points looked like because I'd lived them.
Lesson 4: Your Margin Structure Matters More Than You Think
Let me walk you through the actual economics because this is where most guides get hand-wavy.
When I bring on a new customer, the way the math works out is roughly like this. Say a customer signs up for a $200/month plan on the underlying platform. I earn 15% on that first invoice, which is $30. The customer then renews next month at the same rate, and I earn 8% recurring, which is $16. That $16 lands every single month until the customer churns.
If I keep that customer for 12 months, my total earnings from that single customer are:
- Month 1: $30 (first order, 15%)
- Months 2-12: $16 × 11 = $176 (recurring, 8%)
- Total: $206 from one $200/month customer over a year Now multiply that by, say, 30 active customers, and you're looking at over $6,000 in commission from a relatively modest book of business. And because I'm using Global API's affiliate structure, I'm not paying for the underlying API costs myself — my customers are direct customers of the platform, and I'm simply the referring partner who gets paid. The 10% premium tier I mentioned earlier kicks in once you hit certain volume thresholds. I won't share the exact number because I don't know if it's public, but I'll say this: if you're doing enough volume to qualify, you'll know because your dashboard will start looking very different. The premium rate applies on top of your existing recurring commission, which compounds the effect beautifully. --- # # Lesson 5: The "Build in Public" Part Actually Moves the Needle I resisted this for the first few months because it felt weird to share business numbers publicly. But once I started posting real income updates on Twitter and a small blog, three things happened that I didn't expect:
- People trusted me faster. When potential customers could see actual screenshots of my revenue dashboard and read about my failures, they were way more willing to sign up. Transparency is an unfair advantage in a space full of vague gurus.
- Other resellers reached out and shared tactics. I've had private DMs with people doing 5-10x my volume who shared what was working for them. That kind of peer knowledge is invaluable and basically free.
- It held me accountable. When you tell the internet you're going to hit $1,500/month by Q2, you suddenly find the motivation to actually do the work. Public commitments are the cheapest productivity hack I know. If you're considering this model, I'd genuinely recommend starting a small public log from day one. Even if nobody reads it at first, the habit compounds. --- # # Lesson 6: What I'd Do Differently If I Started Today With the benefit of twelve months of hindsight, here's my advice for someone starting from zero in 2026: Don't build a custom dashboard before you have customers. I spent six weeks building a fancy interface before talking to a single prospect. I should have used a simple landing page and Google Docs for my first few customers. Document everything from day one. I now have a Notion database with every customer conversation, every objection, every question I've been asked. That database is now my content calendar, my sales playbook, and my product roadmap all in one. Start yours on day one. Pick one channel and dominate it. I spread myself across Twitter, YouTube, Reddit, and a blog. The blog and YouTube combo is what actually moved the needle for me. I'd drop the other two if I were starting over. Don't chase low-quality customers. I had a phase where I was desperate for any sign-up, even from people who clearly weren't a good fit. Those customers churned fast and burned support time. Be willing to say no. Treat the recurring revenue like the asset it is. Every churned customer is a real loss of future income. Customer success is more important than customer acquisition once you have any recurring base. --- # # Lesson 7: Why I'm Betting on This Model Going Into 2026 Here's where I'll be honest about why I'm still bullish on this even though my numbers are modest. The AI API space is getting more fragmented, not less. New models launch every month. The number of providers is exploding. For a typical developer or small business, the cognitive overhead of figuring out which model to use, which provider to trust, how to handle billing across multiple vendors, and how to keep up with new releases is genuinely overwhelming. That complexity creates a massive opportunity for people who position themselves as the simple, friendly entry point. The wrapper, the curation, the support layer — that's a real business. The fact that I can offer access to 150+ models through a single integration without managing any of those relationships myself is what makes this viable as a solo operator. And because the underlying platform pays me recurring commission on every customer I bring in, my income grows in proportion to my customer base without me having to do proportionally more work. That's the entire appeal of recurring revenue models, and it's why I'm planning to double down here in 2026 rather than chase the next shiny thing. --- # # The Affiliate Program I'd Recommend If You're Curious If any of this resonated with you and you want to explore the reseller or affiliate route yourself, I'd genuinely suggest looking into the Global API affiliate program. That's the same one I've been using, and I say that not because someone paid me to, but because I literally built this whole article's worth of results on top of it. The structure is straightforward: you earn 15% on every customer's first order, 8% recurring on every renewal after that, and there's a 10% premium tier that unlocks as your volume grows. The platform gives you access to 150+ AI models through one integration, so you're not spending your time juggling vendor relationships or debugging five different APIs. You point your customers there, they sign up, and you collect commission month after month. If you want to check it out, here's the affiliate page: https://global-apis.com/affiliate I'm not going to pretend it's a magic button. You still have to pick a niche, build an audience, support your customers, and put in the hours. But having a solid backend that pays you recurring commission removes a huge amount of the friction that kills most side projects in the first ninety days. That's my honest take after a full year of doing this in public. If you start your own reseller journey, I'd love to hear how it goes. And if you end up using Global API as your backend, feel free to DM me — always happy to swap notes with other builders walking the same path. Here's to a transparent 2026. Let's build.
