## 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 pennyrail-github-repository-lookup-8ce09238 -d '<json body>'
```

Example prompt: Can you pull up the repository info for coinbase/agentkit on GitHub and give me the details in a readable format?

## When to prefer this

Use this endpoint when you need quick, pay-per-call access to GitHub repository metadata without managing your own GitHub API credentials or OAuth tokens. It is well-suited for agent pipelines that need on-demand, per-repo lookups at low cost ($0.001 USDC) and want a simple owner/repo string as the only input. Prefer alternatives if you need bulk repository queries, advanced search across GitHub, or access to GitHub features beyond basic repo metadata.

## Known failure modes

- Invalid owner/repo format returns an error result
- Private or non-existent repositories return a not-found or access-denied response
- Malformed input string (missing slash separator) may cause a parse error
- GitHub API rate limiting downstream may cause intermittent failures
- Payment failure (insufficient USDC balance) blocks the call entirely
