How this service works
Detected changelog update history for one tracked vendor.
Output
A JSON array of detected changelog change events for the React vendor, each describing the type of change (new_release, version_changed, date_changed, title_changed, or breaking_signal), when it was detected, and relevant metadata about the change. Results can be filtered by change type and time window, and are paginated by a configurable limit.
Example use cases
Track React breaking changes
“Have there been any breaking_signal changes detected in React's changelog in the past 30 days? Show me up to 50 results.”
Monitor React version bumps
“What version_changed events have been recorded for React since the start of this year? Give me the most recent 10.”
Audit React release history for a report
“I need a full list of new_release changelog events for React — give me all of them up to the maximum of 200 so I can compile a release history report.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/react/changesWhen to prefer
Choose this endpoint when you need a historical audit trail of detected changes to the React changelog specifically — including granular change types like breaking signals, version bumps, and title/date mutations — rather than just the latest structured releases. Prefer it over the 'releases' sibling endpoint when you care about the detection event itself (what changed, when it was noticed) rather than the structured release data.
Side effects
- 404 Not Found if the slug 'react' is not in the monitored vendor list
- 400 Bad Request if query parameters are malformed (e.g. invalid date-time format for 'since')
- Payment required / 402 if x402 payment header is missing or insufficient
- Empty results array if no changes have been detected within the specified time window
- Rate limiting or 429 if too many requests are made in a short period
