# SignalDesk AI GitHub Release Lookup

> SignalDesk AI GitHub Release Lookup is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Fetches the latest release metadata for any public GitHub repository, including version tag, title, publication date, and asset list.

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 signaldesk-ai-github-release-lookup-eee95108
```

Example prompt: What's the latest release of nodejs/node on GitHub — give me the version tag, release title, and whether it's a prerelease?

## When to prefer this

Use this endpoint when you need quick, structured latest-release data for a public GitHub repository without authenticating to GitHub directly. It is ideal for agents that need to check current software versions, monitor open-source project release cadence, or enrich dependency metadata. Prefer this over scraping GitHub release pages manually or calling the GitHub API directly when you want a pay-per-call, zero-auth approach with cached, transformed output.

## Known failure modes

- Invalid or non-existent repo string returns an error — repo must be in 'owner/repo' format
- Private repositories are not accessible — only public GitHub repos are supported
- GitHub anonymous API rate limits may cause failures under high request volume
- Repo with no releases returns empty or error response
- Malformed repo parameter (too short, wrong format) rejected by input schema validation

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the latest release tag (e.g. 'v26.10.0'), release page URL, release title, publication timestamp, prerelease boolean, asset list, and source metadata including provider name, fetch time, expiry, and source URL.
