## 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 quantaflow-serp-youtube-video-search-6bd3826a -d '<json body>'
```

Example prompt: Search YouTube for 'how to make sourdough bread' and give me the top video results including titles and links.

## When to prefer this

Use this endpoint when you need programmatic access to YouTube search results (SERP data) with a simple per-call micropayment model ($0.01 USDC) and no subscription required. Prefer this over traditional SERP APIs when operating in a web3/DeFi context or when you want pay-as-you-go pricing without API key management.

## Known failure modes

- Payment failure: x402 payment not completed or insufficient USDC balance results in 402 Payment Required
- Invalid query: empty or malformed query string returns upstream error
- Upstream SERP provider unavailable: gateway returns 502 or 503
- Rate limiting: excessive requests may trigger upstream throttling
- No results: obscure or restricted query terms may return empty result set

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns YouTube SERP data including video titles, URLs, channel names, view counts, thumbnails, and other metadata for the search query provided, passed through from the upstream SERP provider after successful x402 micropayment.
