## 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 spipe-answer-api-18f7340a -d '<json body>'
```

Example prompt: Search the web and give me a synthesized answer to this question: 'What are the latest AI agent frameworks released in 2025?' — use English results and make sure the information is fresh.

## When to prefer this

Choose this endpoint when you need a synthesized, research-grade answer to a natural language question backed by live web data — especially when you need freshness control (e.g. recent events), localization (country/language), or a combined search-and-extraction result rather than a raw list of URLs. Ideal for AI agents that need to answer factual or research questions without maintaining their own search index.

## Known failure modes

- Query parameter missing — returns 400 error if 'query' field is not provided
- No results found for very niche or malformed queries
- Payment not received — returns 402 if x402 USDC payment on Base is not completed
- Freshness filter returns no recent results for obscure topics
- Language or country codes not recognized — may default to English/global results
- Slow or failed web content extraction for paywalled or blocked sources
