## 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-search-by-keyword-0ab2ed5b
```

Example prompt: Search GitHub for the most popular repositories related to 'vector database' and show me the top results with their star counts, languages, and descriptions.

## When to prefer this

Use this endpoint when you need to discover and rank GitHub repositories by popularity for a given topic or technology keyword. Ideal for agents helping users find open source libraries, tools, or projects. Prefer this over a generic web search when you specifically want structured GitHub metadata (stars, language, description) rather than blog posts or documentation pages.

## Known failure modes

- No repositories found for obscure or misspelled keywords — returns empty result set
- GitHub API rate limiting causes request failure or degraded results
- Keyword too broad returns generic or irrelevant repositories
- Network timeout if GitHub's search API is slow
- Payment not processed — 402 response requiring USDC payment before result is returned
