## 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 agentutility-github-readme-fetcher-ca8ac8d8 -d '<json body>'
```

Example prompt: Can you pull the raw README markdown from the vercel/next.js GitHub repo so I can summarize what the project does?

## When to prefer this

Use this endpoint when you need the raw markdown content of a GitHub repository's README programmatically, especially in agent workflows that require summarizing, analyzing, or displaying open source project documentation. Prefer this over scraping GitHub directly since it is a paid, reliable, MCP-callable endpoint settled in USDC via x402 with structured JSON output including byte and character counts.

## Known failure modes

- Repository not found or does not exist — likely a 404-equivalent error
- Repository has no README file — empty or null raw_markdown returned
- Invalid repo slug format (missing owner prefix) — malformed request error
- Rate limiting or upstream GitHub API failure — service unavailable response
- Private repository without access — authorization error

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

A JSON object containing the repository slug, source ('github'), byte size of the README, character count, and the full raw markdown text of the README file.
