## 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-recent-releases-for-linear-c9b59923
```

Example prompt: Pull the 10 most recent structured release entries from the Changelog State API for Linear so I can see what they've shipped lately.

## When to prefer this

Use this endpoint when you need structured, machine-readable recent release data specifically for the Linear vendor from a pre-tracked changelog monitor, rather than scraping Linear's changelog page yourself. It is ideal for agents that need to programmatically consume release notes, detect new releases, or summarize recent product updates for Linear without building their own scraper.

## Known failure modes

- Invalid or unrecognized vendor slug returns an error or empty result
- limit parameter out of range (below 1 or above 50) causes a validation error
- Service unavailable or payment failure (x402) prevents data retrieval
- Vendor not tracked by the API returns no results
- Rate limiting or quota exhaustion on the Replit-hosted service

## How this service works

Structured recent releases for one tracked vendor.

## Output

A JSON object containing a list of structured recent release entries for the Linear vendor, including release metadata such as version, date, and changelog content, up to the specified limit (default 10, max 50).

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."
