How this service works
Structured recent releases for one tracked vendor.
Output
A JSON object containing a list of structured release entries for the requested vendor (each with version, publish date, and changelog details), plus an opaque nextCursor token for pagination to older entries.
Example use cases
Track latest AI provider releases
“Fetch the 5 most recent releases for the anthropic vendor from the Changelog State API — I want to see what they've shipped and when.”
Paginate through vendor release history
“Get the next page of release entries for the stripe vendor using this cursor I got from the last response, and show me up to 20 results.”
Monitor competitor changelog updates
“Pull the latest structured release notes for the openai vendor — give me the most recent 10 entries so I can compare what they've been shipping against our roadmap.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/x402?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 monitor list. It is ideal for agents that need to programmatically inspect recent software releases, compare versions, or feed changelog data into downstream workflows. Prefer this over generic web scraping when the vendor is in the tracked set and you need clean, structured output rather than raw HTML.
Side effects
- Passing the literal string '{slug}' or an unresolved path parameter returns 404
- A malformed or cross-vendor cursor returns 400 and is not charged
- An unrecognized vendor slug returns 404
- Requesting limit outside 1–50 returns a validation error
- Service unavailability on the Replit host returns 5xx
