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 including version details and publish metadata, plus an opaque `nextCursor` token for paginating to older entries in newest-first order.
Example use cases
Track viem SDK release history
“Show me the last 10 structured release entries for viem from the changelog tracker — I want to see what versions have shipped recently.”
Monitor OpenAI API changelog updates
“Fetch the latest 5 changelog releases for openai from the changelog state API so I can see what's changed.”
Paginate through full release history
“I already grabbed the first page of releases for viem — can you continue from where I left off using the cursor token I have and get the next 20 entries?”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/viem?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable release data for a specific vendor that is already tracked by the changelog monitoring service, especially when you want to paginate through release history in a stable, cursor-based manner. Prefer this over scraping changelogs or using generic web-search approaches when you need consistent structured output per vendor.
Side effects
- 404 if the literal placeholder `{slug}` is used instead of a real vendor slug
- 400 if a malformed or wrong-vendor cursor token is supplied
- 404 if the requested vendor slug is not tracked by the service
- Payment required / 402 if x402 payment is not provided
- Empty results list if the vendor has no recorded releases
