## 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-github-vendor-releases-3c01dd19
```

Example prompt: Can you pull the latest GitHub releases from the Changelog State API — give me the 10 most recent entries with all the structured details?

## When to prefer this

Choose this endpoint when you need structured, machine-readable release data specifically for the GitHub vendor and want it pre-parsed rather than scraping GitHub's own changelog or release pages. It is ideal for agents monitoring software dependency updates, building release summaries, or triggering workflows on new GitHub releases, especially when you need consistent JSON output with configurable result limits.

## Known failure modes

- Vendor slug not found or not tracked — returns 404 or empty result
- Limit parameter out of range (below 1 or above 50) — returns validation error
- Payment not completed — endpoint returns 402 Payment Required
- Upstream changelog source unavailable — may return stale or partial data
- Rate limiting or quota exceeded — returns 429 or error response

## 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 GitHub vendor, including version identifiers, release dates, and changelog content, up to the requested 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."
