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 2s-io-github-code-search-6cf6950f
```

Example prompt: Search GitHub for all JavaScript files that use the addEventListener function — show me the file names, paths, and repo links for the first 10 results.

## When to prefer this

Use this endpoint when you need to search across all public GitHub code using GitHub's powerful code-search syntax (e.g. scoping by repo, language, filename, or path), without needing a GitHub API key. Ideal for agents that need to find real code examples, discover usage patterns of a library or function, or locate specific files across open-source repositories. Prefer this over raw GitHub API calls when no auth token is available and the cost of $0.001 per call is acceptable.

## Known failure modes

- Empty query string returns validation error (minLength:1 violated)
- Query exceeding 400 characters rejected (maxLength:400 violated)
- Invalid page or perPage values return schema validation errors
- Overly broad queries may return very high match counts with limited per-page results
- GitHub's code search index may not include very recently pushed code
- Rate limits from the underlying GitHub API may cause transient failures

## How this service works

Search code across GitHub with the code-search syntax (e.g. 'defineEndpoint repo:AlleyFord/2s' or 'addEventListener language:js'). Returns total match count + file name, path, repository, and URL for each hit. Read-only; no caller key needed.

## Output

Returns the total number of matching files found on GitHub, plus a list of results each containing the file name, file path, repository name, and direct URL to the file on GitHub.
