## 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-bing-video-search-x402-42750469 -d '<json body>'
```

Example prompt: Search Bing for videos about 'how to make sourdough bread' and return the top results including titles, URLs, and thumbnails.

## When to prefer this

Choose this endpoint when you need programmatic access to Bing video search results with per-call micropayment billing via the x402 protocol, without needing a long-term Bing API subscription or API key management. Ideal for agents that need occasional or bursty video search without upfront commitment.

## Known failure modes

- Payment failure or insufficient USDC balance causes 402 rejection before the search is executed
- Invalid or malformed query parameters result in upstream API errors
- Bing API rate limits or quota exhaustion may cause upstream 429 or 503 errors
- Missing or malformed path/query fields return gateway-level errors
- Empty result sets for highly specific or obscure queries
