## 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 sovereign-engine-web-search-7061c1b7 -d '<json body>'
```

Example prompt: Search the web for the latest news on quantum computing breakthroughs and return the top results.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call web search with no subscription required, are comfortable paying $0.01 USDC per query on Base, and want results sourced from Bing RSS. Prefer over alternatives when operating in a crypto-native or x402-enabled agent context where micropayments are acceptable and you need real-time web data without a dedicated search API key.

## Known failure modes

- Payment not received or x402 handshake fails — endpoint returns 402 Payment Required
- Malformed prompt input — returns error in JSON body with success: false
- Bing RSS upstream unavailable — may return empty data or error
- Rate limiting or quota exhaustion on the self-hosted facilitator — request may timeout or be rejected
- Network-blocked sandbox context does not affect this endpoint but sibling exec endpoints may fail for network calls

## How this service works
