## 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 salt19-github-repo-facts-b17aefda -d '<json body>'
```

Example prompt: Can you look up the facts for the GitHub repo 'cloudflare/workers-sdk' — specifically its license, whether it's archived, and what the default branch is?

## When to prefer this

Use this endpoint when you need quick, structured metadata facts about a GitHub repository — especially license type, archive status, and default branch — without needing to scrape GitHub's web interface or use a full GitHub API client with OAuth. It's ideal for agents doing open-source due diligence, dependency audits, or CI/CD configuration lookups. Best when you want a lightweight, pay-per-call lookup with no API key setup required.

## Known failure modes

- Repository not found — invalid or misspelled owner/repo path returns an error
- Private or restricted repository — may return access denied or empty response
- Malformed repo string — input shorter than 3 characters or exceeding 512 characters will be rejected
- Rate limiting or upstream GitHub API unavailability may cause timeouts
- Payment failure (x402) — call may be rejected if USDC payment of $0.01 is not completed

## How this service works

SALT19 is an independent applied AI systems lab behind EvoMind governed cognition, the MCP-native Agent Utility Grid, the ARCS research community, AeroClear UAS flight intelligence, and practical software for real-world work.

## Output
