## 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 skill-audit-llm-web-answer-api-db9a15d3 -d '<json body>'
```

Example prompt: Search the live web and tell me what the x402 payment-required header contains — I need a concise answer with sources, keep it under 500 tokens and read up to 4 pages.

## When to prefer this

Choose this endpoint when you need a grounded, cited answer synthesized from live web content rather than the model's training data — especially for current events, recent specifications, or fast-changing facts. Prefer it over static knowledge bases when freshness matters and over raw search APIs when you need a coherent natural-language summary rather than a ranked list of raw snippets.

## Known failure modes

- Query returns no relevant web results — answer may be empty or low quality
- max_sources set too low (1-2) for complex topics leading to incomplete answers
- Rate limiting or payment failure via x402 micropayment protocol returning 402
- Live web pages are unavailable or blocked, reducing source quality
- max_tokens too low truncates the answer mid-sentence
