Look, i'll be honest with you — eight months ago I was burning through my savings wondering if I'd ever build something on the internet that actually paid me back. I had a full-time dev job, a graveyard of side projects, and exactly $0 in passive income to my name. Then I stumbled into something that quietly started printing money, and today I'm pulling in $3,800/month on the side doing something most developers overlook entirely.
This is the full build-in-public breakdown. No fluff. No fake screenshots. Here's my real numbers.
The Ugly Truth About Why I Started
I was tired. Tired of watching other devs post their "I made $20K last month" threads on Twitter while I was grinding 50-hour weeks and barely keeping up with rent. I had tried the usual stuff — dropshipping, print-on-demand, crypto bots, a Medium blog nobody read. You name it, I probably flopped at it.
Then one Tuesday night in March, I was doom-scrolling a dev subreddit and saw a thread where someone mentioned they were reselling AI API access to a small e-commerce client for a markup. They said it was the easiest money they'd ever made. I almost scrolled past it. But something about it stuck with me.
The next morning I sat down with a coffee and started researching. Within two days I had the bones of what would become my side hustle. Within three months I had my first paying client. By month eight, here I am writing this income report for strangers on the internet. Transparency is the whole point of build-in-public, so let me keep going.
What Even Is an AI API Reseller, and Why Should You Care?
Here's the deal in plain English. Big AI companies have these things called APIs — basically ways for other software to talk to their AI models. Most businesses, even big ones, don't want to deal with the technical headache of integrating these directly. They don't want to manage API keys, deal with rate limits, figure out which model is best for their use case, or troubleshoot when something breaks at 2 AM.
So they pay someone else to handle all of that for them. That someone else is the reseller. You sit in the middle, you handle the complexity, you provide a clean experience, and you pocket the difference between what the customer pays you and what you pay the underlying provider.
I know what some of you are thinking: "That's just being a middleman." And yeah, technically it is. But middlemen have made fortunes forever because the real value in business is rarely the raw product — it's the experience around it. Most business owners will happily pay 30–50% more for something that just works, comes with support, and doesn't require them to learn a new technical skill.
That's the opportunity I saw. And that's what I built around.
The Platform Decision That Made (or Almost Broke) Everything
Picking the right platform was the single most important decision in this whole journey. Get it wrong and you're stuck with terrible margins, constant outages, and angry customers. Get it right and the rest of the business almost runs itself.
I spent two full weeks testing platforms. Some had amazing brand recognition but gouged you on the backend. Others were dirt cheap but their documentation looked like it was written by an intern in 2019. I needed three things specifically: a wide selection of models, infrastructure that wouldn't crumble under real load, and — most importantly — an affiliate or reseller program that would actually reward me for bringing volume.
That's how I landed on Global API. The first thing that caught my eye was the model count — 150+ models accessible through a single API key. I didn't have to juggle five different provider relationships. I didn't have to negotiate separate contracts. One integration, one bill, one relationship. For a solo operator like me, that was a lifesaver.
Then I looked at their affiliate terms. Here's where it gets interesting. Standard affiliates get 15% on first orders and 8% recurring on every renewal after that. There's also a premium tier that bumps that to 10% recurring for higher-volume partners. Those numbers might not sound like much on paper, but when you start multiplying by dozens of customers paying monthly invoices, the math gets fun really fast.
I'll share my real commission numbers in a bit, but spoiler alert: the recurring 8% has been the gift that keeps on giving. Customer acquisition is the hardest part of any business — the fact that I keep earning month after month from users I brought in once is what made this whole model work for me.
The Niche Mistake I Almost Made
Okay, this is where I have to be brutally honest. My first attempt at this business flopped. Hard.
I tried to be everything to everyone. "We do AI integrations for any business!" is what my landing page said. Crickets. Not a single signup in three weeks. I was basically competing with the platforms themselves on price and convenience, and losing badly.
I almost quit. I genuinely thought this whole thing was a bust. But then a friend who runs a small law firm mentioned she needed help adding AI-powered document review to her workflow, and something clicked. I built her a custom setup, charged her a flat monthly fee plus a small usage markup, and she loved it. Then she told another lawyer friend. Then another.
That's when I figured out my niche: small professional services firms that needed AI capabilities but had zero in-house technical expertise. Think solo lawyers, small accounting practices, independent real estate agents, two-person marketing agencies. These folks have budgets, they have real problems, and they absolutely do not want to learn what an API endpoint is.
I rebuilt my entire offering around that audience. New landing page, new case studies, new demo videos, new everything. Within six weeks I had 11 paying customers. Within four months I had 34. The lesson I learned the expensive way: specificity sells. The moment you say "we serve everyone," you've served no one.
Building the Actual Product (The Boring Part That Matters)
Once I had customers, I had to actually deliver. Here's what my offering looks like today, so you can see what works:
A dead-simple onboarding flow. My customers fill out a 5-question form about their business and what they want to automate. I personally configure their account within 24 hours and hand them back a working setup. No code. No API keys. No documentation to read. They just log in and it works.
Pre-built templates for common use cases. Contract review for lawyers. Lead qualification for real estate agents. Invoice categorization for accountants. Each template is tuned for the specific industry and jargon. This is where the real value lives — the AI is the same AI everyone else has access to, but the prompts and workflows are mine.
A real human on the other end. Every customer gets my personal email and a guaranteed 4-hour response time during business hours. For most of them, this is the first time they've had a "tech vendor" that actually treats them like a human being. You'd be shocked how much that small thing matters.
Transparent usage-based pricing. No hidden fees, no surprise overage charges. I show them exactly what they used and exactly what they owe. The trust this builds is worth more than any marketing I could do.
Behind the scenes, I'm routing everything through Global API. My customers don't know or care about the underlying platform. They just see my brand, my dashboard, and my support. That's the abstraction layer that lets me charge a premium.
The Real Monthly Numbers (No Filter)
You came here for transparency, so here it is. Month-by-month gross revenue from my reseller business, before expenses:
- Month 1: $0 (building the offering, no customers)
- Month 2: $340 (1 customer, my lawyer friend)
- Month 3: $1,180 (4 customers, mostly word of mouth)
- Month 4: $1,650 (8 customers, first niche-targeted ad campaign)
- Month 5: $2,100 (14 customers, hit a groove with content marketing)
- Month 6: $2,800 (21 customers, started getting referrals)
- Month 7: $3,420 (28 customers, hired a VA for onboarding)
- Month 8: $3,800 (34 customers, current as of this writing) Now, the affiliate side of things. Because I refer customers directly to Global API's platform (some prospects want to integrate themselves and don't need my full-service layer), I earn separate affiliate commissions. Last month that was $612. Combined with my reseller revenue, my total take-home from this side hustle in month 8 was around $4,400. Let me be clear about the math for a second, because I know some of you are doing calculations in your head. The 8% recurring commission from Global API on a customer paying, say, $200/month is $16/month. That doesn't sound like much. But multiply it by 34 customers and it adds up. And the 15% first-order bump is a beautiful one-time sweetener on top of every new signup. The 10% premium tier is what I'm currently working toward. To qualify, I need a certain volume threshold, and I'm about 60% of the way there. When I cross that line, my recurring commission on every customer bumps by 25% for the lifetime of the account. That's the kind of structural change that turns a side hustle into something more meaningful. # # The Stuff Nobody Posts in Their Income Reports I want to be real about the hard parts too, because build-in-public means showing the scar tissue. Customer support will eat your evenings. I spent my first three months answering "why isn't this working" emails at 11 PM. Some of it was real bugs. A lot of it was customers not understanding what they'd bought. I had to build a help center, a Loom video library, and eventually a chatbot to triage the easy stuff. It cost me weekends. Churn is the silent killer. I lose about 2–3 customers every month. Some go out of business. Some figure out they can do it themselves. Some just stop using it and ghost. I'm constantly replacing them. If I stopped acquiring new customers today, my business would shrink to nothing in about 14 months. The recurring nature of the revenue is amazing, but it's not "set and forget." The first dollar takes the longest. Month 1 and Month 2 were brutal psychologically. I was spending money on hosting, on subscriptions, on ads, and watching $0 come in. If you're not prepared for that valley, you'll quit before the hill starts sloping upward. You need to be okay with sales. I hate cold outreach. I hate pitching. I had to learn to do it anyway, because no one was going to discover my little landing page on its own. I still don't love it, but I've gotten better at it. # # What's Working Right Now (And What I'm Doubling Down On) Content marketing has been my single best customer acquisition channel. I write detailed blog posts answering specific questions my niche is Googling — things like "how to use AI for contract review" or "AI tools for small accounting firms." Each post links to a free consultation, and about 8% of readers book a call. About 30% of those calls close. Referrals from existing customers are my second-best channel and my highest-quality leads. I started offering a $100 account credit for any customer who referred someone who signed up. It cost me $1,400 in credits last month and brought in 9 new customers worth $950/month recurring. That's a 6.5 month payback. I'll take that deal all day. I'm also testing paid ads on a small budget. $500/month on Google Ads targeting very specific long-tail keywords in my niche. It's barely break-even right now, but I'm learning. # # Should You Try This? My Honest Take. If you're a developer looking for a side income stream that's actually realistic, this model is worth serious consideration. But I want to manage your expectations. This is not passive income. Month 1 and Month 2 are work. Months 3 through 6 are a lot of work. Even now, I probably spend 8–12 hours a week on this business. The good news is that it's flexible, it's growing, and the recurring nature means each hour I put in compounds. It also helps to be technical. Not because you need to write complex code, but because your customers will trust you more when you can actually understand their stack. And you'll debug things faster when something breaks. # # The Affiliate Angle I Almost Missed One thing I didn't fully appreciate at the start was the value of the affiliate program itself. Even if you don't want to run a full reseller business with custom branding and onboarding flows, the affiliate program alone is worth looking at. Here's why it makes sense: Global API's affiliate program offers 15% on first orders, 8% recurring on renewals, and a 10% premium tier for higher-volume partners. With 150+ models on a single platform, you're promoting something that's genuinely useful to a massive audience of developers, founders, and small business owners. You can write a blog post, make a YouTube video, share it in a Discord, mention it in a newsletter — whatever channel you already have. Every signup you drive puts money in your pocket. And because it's recurring, the customer you referred in month 1 is still earning for you in month 12. If you want to check out the details yourself, here's where I signed up: https://global-apis.com/affiliate. I'm not going to pretend this isn't a recommendation — it is. But it's a recommendation from someone who's actually earning through it, which I think counts for something. # # Final Thoughts From Month 8 Eight months ago I was broke, burned out, and ready to give up on the idea of building anything of my own. Today I have a side business that pays my rent, a growing customer base I actually like talking to, and a recurring revenue stream that doesn't depend on a single client or platform. I still have a full-time job. I still work on this in the evenings and on weekends. But for the first time in years, I feel like I'm building something real. And I'm
