How this service works
Structured recent releases for one tracked vendor.
Output
A JSON object containing an array of structured release entries for the requested vendor (each entry includes version, publish date, and release notes or summary), along with a 'nextCursor' token for paginating to older entries. If no more entries exist, nextCursor will be absent or empty.
Example use cases
Track TypeScript version history
“Pull the last 10 releases for TypeScript from the changelog tracker so I can see what versions have shipped recently.”
Paginate through release history
“Get me the next page of TypeScript changelog entries — here's the cursor from my last request: <cursor_value>.”
Monitor vendor releases in automation
“Fetch the 5 most recent structured release entries for TypeScript so my pipeline can check whether a new version dropped since yesterday.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/typescript?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, paginated release data for a specific vendor that is already tracked by the Changelog State API service. It is ideal for automation pipelines, changelog monitoring agents, or dashboards that need machine-readable release entries. Prefer it over scraping vendor websites directly when the vendor is in the supported monitor list. For discovering which vendors are available, first call GET /api/monitors.
Side effects
- 404 if the vendor slug does not exist in the monitored list — must use a valid slug from GET /api/monitors
- 400 if the cursor token is malformed or was issued for a different vendor
- Payment failure if the x402 payment header is missing or insufficient (the call is not charged on 400 errors)
- Empty results array if the vendor has no recorded releases yet
