Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Show me the 10 most recent structured release entries for Chainlink from the Changelog State API so I can see what versions have shipped lately.

## When to prefer this

Use this endpoint when you specifically need structured, machine-readable release data for Chainlink and want pagination support for walking through historical entries. Prefer it over scraping Chainlink's own site when you need normalized, consistently formatted release records without parsing HTML. It is the right choice when building automated monitors, CI integrations, or dashboards that need to detect new Chainlink releases programmatically.

## Known failure modes

- 400 Bad Request if the cursor token is malformed or was issued for a different vendor
- 404 Not Found if the slug literal '{slug}' is used instead of a real vendor name
- Payment failure or 402 if x402 payment is not properly handled
- Empty results list if Chainlink has no tracked releases yet
- Rate limiting or server errors from Replit hosting

## How this service works

Structured recent releases for one tracked vendor.

## Output

A JSON object containing a list of structured release entries for Chainlink (version names, dates, descriptions, etc.) up to the requested limit, plus an opaque nextCursor token to retrieve the next page of older results in newest-first order.

It does not expire; a walk can be paused and resumed. Do not construct or edit one: a token that is malformed, or was issued for a different vendor, is refused with 400 and is never charged."
