How this service works
Structured recent releases for one tracked vendor.
Output
A JSON object containing a list of structured release entries for OpenZeppelin (newest first), each with version, publish date, and changelog details, plus an opaque `nextCursor` token for fetching older pages. Returns up to the requested limit (default 5, max 50) per page.
Example use cases
Breaking change alert for smart contracts
“Pull the latest OpenZeppelin releases and tell me if any of them include breaking changes to their contracts library — I'm on v4.9 and want to know if upgrading is risky.”
Automated dependency update triage
“Fetch the last 10 OpenZeppelin releases and summarize what changed so I can decide whether to bump the version in our Solidity project.”
Paginated changelog audit
“Get me the first page of recent OpenZeppelin releases and then the next page after that — I want to review everything from the past few months.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/openzeppelin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need machine-readable, paginated release data specifically for OpenZeppelin from a pre-monitored feed, rather than scraping GitHub releases or npm yourself. It is ideal for agents that need to react to new OpenZeppelin versions, audit recent changes, or maintain up-to-date dependency intelligence without building custom changelog parsing. Prefer it over general web-scraping tools when low-latency structured output and cursor-based pagination are needed.
Side effects
- Invalid or malformed cursor returns HTTP 400 and is not charged
- Unknown or unsupported vendor slug returns an error (use GET /api/monitors to list valid slugs)
- Limit out of range (below 1 or above 50) returns a validation error
- Service unavailable or upstream changelog fetch failure returns 5xx
- Empty result set if no releases have been detected yet for the vendor
