## 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 sitecheck-github-releases-lookup-b508c791
```

Example prompt: Can you pull the last 5 releases for the cloudflare/workers-sdk GitHub repo and show me the release names, dates, and whether any are pre-releases?

## When to prefer this

Choose this endpoint when you need structured release data from a GitHub repository without direct GitHub API credentials, want pay-per-call pricing, or are building an agent workflow that checks release histories across multiple projects. Prefer it over raw GitHub API calls when you need a simple, normalized JSON response without OAuth setup.

## Known failure modes

- Invalid or non-existent repository name returns an error
- Private repositories without access return a not-found or forbidden error
- Malformed repo parameter (not owner/name format) may cause a bad request
- Limit parameter outside 1-10 range may be clamped or rejected
- GitHub API rate limits on the backend could cause transient failures

## How this service works

The latest releases of a GitHub repository: tag, name, date, pre-release flag, the first 1,500 characters of the notes, and the number of assets. Needs the GITHUB_TOKEN secret on the deployment; without it the call answers 503 and is not charged.

## Output

Returns a JSON object with the repository name, source URL, a list of releases (each with tag, name, body/notes, link, asset count, publish date, and prerelease flag), and the timestamp the check was performed.
