# Changelog State API – Node.js Releases

> Changelog State API – Node.js Releases is a paid API for AI agents from changelog-state-api.replit.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Returns structured, paginated recent release entries for the Node.js vendor tracked by the Changelog State API.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

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

```sh
zero fetch --capability changelog-state-api-node-js-releases-9c73fc6d
```

Example prompt: What are the 10 most recent Node.js releases? Pull the structured release data from the Changelog State API so I can see version numbers and dates.

## When to prefer this

Use this endpoint when you need structured, machine-readable Node.js release data without scraping the official Node.js site or GitHub releases page. It is ideal for agents that need to monitor for new Node.js versions, build upgrade automation, or enrich CI/CD pipelines with version awareness. Prefer this over generic web scraping when you need a consistent, paginated JSON format.

## Known failure modes

- 400 Bad Request – malformed or vendor-mismatched cursor token (not charged)
- 404 Not Found – literal `{slug}` used instead of a real vendor slug like `nodejs`
- Rate limiting or payment failure for the $0.01 USDC x402 charge
- Empty result set if Node.js has no tracked releases yet
- Invalid limit value outside 1–50 range

## How this service works

Structured recent releases for one tracked vendor.

## Output

A JSON object containing a list of structured release entries for Node.js, each with version number, release date, and changelog details, plus an opaque `nextCursor` token for paginating to older entries.

It names a position in the newest-first order rather than an offset, so a page you have already read never shifts under you: an entry that arrives mid-walk takes the place its own publish date gives it — above the cursor, on ground you have already covered, or below it, still ahead of you — instead of renumbering every page behind it. 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."
