Overview

Changelogs.md aggregates and structures changelog data from popular open source projects hosted on GitHub, making it easy to fetch and display version history programmatically. The API is free to use with no authentication required. It is handy for building dependency-tracking tools or dashboards that show what changed across libraries your project uses.

💡

Beginner Tip

No API key is needed. Query a project's changelog by its GitHub owner and repo name in the URL path. Note that only projects with a CHANGELOG.md or similar file in their GitHub repo will return results.

Common Errors & Troubleshooting

404 Not Found The requested GitHub repository does not have a recognized changelog file, or the owner/repo path is incorrect.
✓ Verify the exact GitHub username and repository name, and check that the repo has a CHANGELOG.md, CHANGELOG, or HISTORY.md file at its root.
Empty versions array The changelog file exists but could not be parsed into structured version entries.
✓ The project changelog may use a non-standard format; check the raw changelog file on GitHub for the actual format.
Stale data The API caches changelog data and may not reflect the very latest release.
✓ Allow a few hours for new releases to be indexed; for real-time data, parse the GitHub releases API directly.
