## 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 github-repository-tags-lookup-c8218bac
```

Example prompt: Can you list all the tags on the GitHub repository 'facebook/react' so I can see what versions have been released?

## When to prefer this

Choose this endpoint when you need to list GitHub repository tags without managing a GitHub API key or OAuth credentials — payment via USDC over x402 serves as the identity. Ideal for AI agents that need lightweight, keyless access to GitHub metadata in automated pipelines.

## Known failure modes

- Invalid or non-existent repository returns an error or empty tag list
- Missing or malformed schema parameter may result in a 400 bad request
- Payment failure via x402 (insufficient USDC balance) returns a 402 Payment Required response
- Rate limiting or GitHub API unavailability causes upstream errors
- Private repository without proper credentials returns access denied

## How this service works

## Output

Returns a JSON object with ok and paid status flags, along with a list of tags (names/refs) from the specified GitHub repository, enabling the caller to enumerate all tagged versions or releases.
