About APIWatch
What is APIWatch?
APIWatch is a third-party API changelog aggregator and breaking-change alert system. We track over 200 APIs across payments, AI/ML, cloud infrastructure, developer tools, authentication, communication, and data services. Instead of manually checking dozens of changelog pages, release notes, and blog posts, you can browse everything in one unified feed.
How We Collect Data
Every day at 6:00 AM UTC, our automated system polls RSS feeds, GitHub Releases pages, and dedicated changelog endpoints for every tracked API. New entries are compared against existing records to avoid duplicates, then classified by severity and stored.
Severity Classification
Each changelog entry is automatically tagged with one of five severity levels using keyword analysis:
- Breaking — Removals, sunsets, end-of-life notices
- Deprecation — Features marked for future removal
- Feature — New capabilities and launches
- Fix — Bug fixes and patches
- Info — General announcements and documentation updates
Frequently Asked Questions
Is it free?
Yes, APIWatch is completely free. All tracked APIs and changelog data are available to everyone at no cost.
How often are changelogs checked?
Our system polls all tracked API sources daily at 6:00 AM UTC. This means new entries typically appear within 24 hours of being published.
Can I request an API to be added?
Absolutely! Send us an email or use the community request form. We're always looking to expand our coverage to include the APIs developers care about.
Who made this?
APIWatch was built by an independent developer who got tired of being blindsided by breaking API changes. If you find it useful, consider buying me a coffee!
