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 bitcoin-tech-radar-release-monitor-1f53fc49
```

Example prompt: What are the latest release versions of Bitcoin Core and the major Lightning Network implementations right now, and have any of them mentioned security fixes in their release notes?

## When to prefer this

Choose this endpoint when you need a single aggregated snapshot of release status across all major Bitcoin and Lightning Network software projects, especially when checking for security-related releases. It is preferable to scraping individual GitHub repos manually and is purpose-built for Bitcoin infrastructure monitoring use cases.

## Known failure modes

- GitHub rate limiting may cause stale or missing data
- A project with no recent GitHub release will return null or empty fields
- Network timeout from Vercel to GitHub may result in a 503 or partial response
- Incorrectly parsed security keyword flag if release notes use non-standard phrasing

## How this service works

Latest releases of Bitcoin Core and the Lightning implementations (LND, Core Lightning, Eclair, LDK) as JSON: version, date, days since release, link to notes, and a plain keyword flag when notes mention security fixes. Read live from GitHub.

## Output

A JSON object containing, for each tracked project (Bitcoin Core, LND, Core Lightning, Eclair, LDK): the latest version string, release date, number of days since that release, a URL linking to the official release notes, and a boolean or keyword flag indicating whether the release notes mention security fixes.
