I have six APIs running on a VPS right now. A dead link checker, an SEO auditor, a screenshot capture tool, a page performance analyzer, a tech stack detector, and an SSL certificate checker.
They all work. They all have interactive tool pages. They all have OpenAPI specs, structured data, sitemaps, and IndexNow pings. Three of them are listed on RapidAPI with paid tiers.
Total paying customers: zero.
The Build vs. Distribution Gap
Every developer knows the feeling. You ship something, you're proud of it, and then... silence.
I've been tracking my server's access logs obsessively. Here's what actual traffic looks like for a new API service with no marketing budget:
- 438 requests in the first 24 hours
- 60 unique IPs
- Roughly 30 of those are bots (YandexBot, security scanners, mystery crawlers)
- Another 25 are automated probes trying to find
.envfiles, PHP shells, and Spring Boot actuators - ~5 appear to be legitimate tools evaluating my pages
- 1 actual human visitor (and that might be me checking from my phone)
Nobody is using the APIs. Nobody knows they exist.
What I Tried
Content marketing: I published 15 articles on Dev.to. The story-format articles got 10-23 views each. The API tutorials got 0-4. None of them drove a single referral to my site.
API directories: I submitted to apilist.fun (still pending), explored 12 other directories. Most require GitHub accounts or have broken submission forms.
RapidAPI marketplace: My three paid APIs are live, but RapidAPI search returns the same popularity-ranked results regardless of what you search for. If you're not already popular, you're invisible.
SEO: JSON-LD structured data, Open Graph tags, canonical URLs, sitemap.xml, robots.txt, IndexNow. YandexBot indexes my pages within 30 seconds of submission. Googlebot? Haven't seen it yet.
What Actually Happened
The interesting part isn't the silence — it's what breaks it.
YandexBot showed up first and became my most reliable indexer. Every time I submit a new page via IndexNow, YandexBot crawls it within 30 seconds. It's crawled my tool pages, my OpenAPI specs, even my RSS feed. Yandex may not drive traffic, but it proves the infrastructure works.
toolhub-bot appeared from a UK company called WorkTitans. It started by crawling one tool page, then came back for more. Someone is building a directory of developer tools, and mine showed up on their radar.
Mystery AWS crawlers appeared using old Internet Explorer user agents with Google referrers. Multiple IPs, each checking exactly one tool page, all within 3 seconds. Something in Google's ecosystem is evaluating my pages.
Two RSS readers started monitoring my feed from Hetzner datacenter IPs in Germany.
None of this is revenue. But it's the machinery of discovery grinding into gear.
The Uncomfortable Truth
Building APIs is a solved problem. A competent developer can ship a working API in an afternoon. What takes months is getting anyone to know about it.
The funnel looks like this:
Build API → List it → Get indexed → Get discovered → Get evaluated → Get tried → Get used → Get paid
I'm stuck between "Get indexed" and "Get discovered." The bots have found me. The crawlers are evaluating me. But the humans who would actually type a URL into RapidAPI's test console haven't arrived yet.
What I'm Going to Do About It
- Keep publishing story-format articles — they outperform tutorials 5-to-1 on Dev.to
- Wait for search engine indexing — Yandex is fast, Google is slow, organic traffic takes weeks
- Monitor the crawlers — each new bot that finds my tool pages is a potential distribution channel
- Stop building and start distributing — the 7th API won't help if the first 6 have zero users
If you've built something nobody uses yet, you're not alone. The gap between "it works" and "people use it" is the hardest gap in software.
If you want to try the APIs yourself:
- Dead Link Checker — find broken links on any webpage
- SEO Audit — check title, meta, headings, images, links
- Website Screenshot — capture any URL as PNG
All three have free tiers on RapidAPI.
