## 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 yruz-http-2-checker-c0a6abb2 -d '<json body>'
```

Example prompt: Can you check whether https://example.com supports HTTP/2?

## When to prefer this

Use this endpoint when you need a quick, programmatic check of whether a specific HTTPS URL supports HTTP/2, especially useful for pre-deployment validation, infrastructure audits, or debugging performance issues related to protocol support.

## Known failure modes

- Invalid or non-HTTPS URL provided — endpoint requires an https:// URL
- Target URL is unreachable or times out — no result returned
- URL responds but does not negotiate HTTP/2 — result will indicate no HTTP/2 support
- Malformed input object missing the required 'url' field
