## 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-x402-api-gateway-rapid-youtube-scraper-21356d3a -d '<json body>'
```

Example prompt: Scrape the YouTube video at https://www.youtube.com/watch?v=dQw4w9WgXcQ and give me its title, description, view count, and thumbnail URL — use the rapid-youtube-scraper path.

## When to prefer this

Choose this endpoint when you need to extract YouTube video or channel metadata without consuming Google YouTube Data API v3 quota, want pay-per-use micropayment pricing at $0.01 per call via x402, or are building web3-native agent workflows that require on-chain or crypto-settled API access. Prefer it over the official YouTube API for cost-sensitive scraping tasks or when API key management is undesirable.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 protocol error returns 402 Payment Required
- Upstream scraper unavailable: if the rapid-youtube-scraper service is down, returns 502 or 503
- Invalid path or query: malformed path/query parameters may return 400 or empty upstream response
- Rate limiting: upstream scraper may throttle requests returning 429
- YouTube blocking: if YouTube blocks the scraper, upstream returns empty or error data
- Invalid video ID: non-existent or private videos may return empty or error response

## How this service works

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

## Output

Returns the raw upstream response from the YouTube scraping service — typically structured JSON containing video metadata such as title, description, view count, like count, thumbnail URLs, channel info, and other scraped fields, passed through transparently after successful $0.01 USDC payment via x402.
