## 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 superhighway-nlp-web-search-11044155
```

Example prompt: Search the live web for the latest news about OpenAI's newest model releases and give me the results as clean readable text.

## When to prefer this

Use this endpoint when an AI agent needs live, current web information beyond its training cutoff — especially for recent news, real-time facts, or reading arbitrary web pages as clean markdown. Prefer this over static knowledge bases when freshness and live web access matter. The pay-per-call micropayment model (x402, $0.001 USDC) makes it cost-effective for sporadic or bursty agent workloads without subscription overhead.

## Known failure modes

- Empty or vague query returns low-relevance results
- Network or upstream search provider unavailable returns 5xx error
- Payment not included or insufficient balance returns 402 Payment Required
- Rate limiting may occur on high-frequency calls
- Pages behind paywalls or login walls may return partial or no content
