Selling Niche Data APIs to Professionals Who Hate Web Scraping

In a world overflowing with information, there’s one constant headache for professionals in research-heavy industries: data collection. Whether they’re recruiters looking for candidate profiles, marketers tracking competitors, real estate agents analyzing listings, or financial analysts scanning local regulations, they all need data — often from messy, unstructured, constantly changing sources. The average person in these roles doesn’t know how to scrape websites, normalize data, or build clean databases. And they definitely don’t want to. What they want is a clean, reliable pipe of information — something they can plug into and use without worrying about maintenance or legality. That’s where a well-crafted, subscription-based niche API becomes a quietly powerful business.

Let’s say you’ve built a scraper that collects newly listed short-term rentals from public municipal databases in major cities. This is information that Airbnb investors and property managers desperately want, but which is usually buried behind clunky interfaces or PDF reports that no one wants to read. If you clean that data, normalize the fields, tag it by city and zoning code, and expose it through an API or even downloadable CSVs, you now have something valuable. You didn’t create the data — you just made it usable, accessible, and timely. And that’s exactly what your customers will pay for.

You don’t need to build the next Stripe to monetize this. A basic Flask or FastAPI backend, hosted on a $20 VPS, can serve structured data reliably. Authentication tokens can be managed with simple API key logic. You could launch an MVP in a weekend. The real effort lies in creating robust scrapers or data pipelines and ensuring the freshness of the content. But once it’s running, your API becomes an automated product: new data in, cleaned data out, money in your Stripe account. It scales quietly.

Buyers for this kind of service are everywhere, but they’re not hanging out in the usual tech places. They’re inside Slack groups for real estate investors. They’re in forums for market researchers. They’re lurking in Subreddits and Facebook groups asking, “Does anyone know how to get this data more easily?” If you show up with a clean solution, a clear demo, and a flat monthly fee, you don’t need 10,000 users. Ten serious customers at $100/month already gets you to $1,000 recurring revenue — with almost zero marginal cost once the system is built.

This isn’t glamorous software. You won’t get on Product Hunt or TechCrunch. But you will get wire transfers from companies and independent professionals who don’t have time to figure this stuff out. If you niche down far enough, you’ll even find clients who are happy to pay more for exclusive access to certain datasets or custom endpoints. And as regulations change or sites evolve, your product becomes stickier because it spares customers the pain of keeping up.

APIs are infrastructure, and infrastructure, when focused and stable, is worth paying for. Especially when the alternative is doing everything manually. This model has been used successfully in industries as dull-sounding as trucking, insurance compliance, state-level legislation, and even cemetery plot listings. The less glamorous the vertical, the fewer competitors you’ll have — and the more value your clean, structured feed provides.

This is a business model made for technical builders who prefer simple systems over flashy features. You use software to do something unsexy but useful. You sell access to the clean output. And you quietly grow a stream of recurring income while others chase trends.
