Last Tuesday, 2 AM. Production down.
Stripe pushed a minor API update. Changelog? Buried. Email notification? Missed. My code? Broken.
6 hours of debugging. 3 cups of coffee. 1 very angry client.
The worst part? This wasn't the first time. And it won't be the last.
The Real Problem
YC just declared "Self-Maintaining APIs" as a billion-dollar opportunity in their Fall 2026 Requests for Startups.
Why? Because 30% of AWS downtime used to come from external API changes going unnoticed.
And it's not just AWS. Every developer knows the pain:
- Breaking changes ship with zero warning
- Changelogs are walls of text nobody reads
- Your code breaks before you even know something changed
- You spend hours debugging what should have been a 5-minute fix
I checked G2 reviews. 222+ developers complaining about the same thing on Postman alone. Swagger users losing data on every reload. ReadMe search so broken it returns nothing useful 9 out of 10 times.
What I Built
API Sync Agent — an AI agent that:
- Monitors your API providers 24/7
- Detects breaking changes, deprecations, and new features instantly
- Scans your codebase for affected code
- Auto-generates a fix PR — you just review and merge
No more 2 AM debugging. No more missed changelogs. No more "how did this break?"
The Bigger Picture
This isn't just a tool. It's a shift in how developers work with APIs.
Right now, every developer is a human changelog reader. That's not sustainable.
AI should handle the monitoring. Humans should handle the decisions.
Want Early Access?
I'm building this in public. Join the waitlist if you want to never worry about API breaking changes again.

No spam. Just a heads up when early access is ready.
