## 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 web-research-8-pages-5ff9f6fd -d '<json body>'
```

Example prompt: Can you research 'what are the long-term health effects of seed oils' by reading the top 8 pages and pulling out the 15 most relevant passages with their sources? Use results from the last month and search from a US perspective.

## When to prefer this

Choose this endpoint when you need evidence from multiple websites rather than a single snippet — ideal for research tasks requiring synthesis across sources. It is more comprehensive than a basic search API and cheaper than running equivalent research on Exa or Firecrawl. Prefer it over single-page readers when you need multi-source validation, citation-backed answers, or when the question cannot be answered from one page alone. Use Deep Research (web + papers) instead if you also need academic paper coverage or sub-question decomposition.

## Known failure modes

- Pages behind paywalls or login walls may not be fully readable
- Some pages may return empty or low-quality content reducing effective page count
- Query too broad may yield low-relevance passages
- Freshness filters may reduce available results for very recent events
- Rate limiting or worker errors may return 5xx responses
- Pages with heavy JavaScript rendering may yield incomplete markdown

## How this service works

Web search API for AI agents, pay per call in USDC (x402, Base / Polygon / Solana; no account, no API key). Google-quality results re-ranked for authority and merged with papers, code and news; search + read pages in one call; extractive answers with citations; Google as seen from any country or city (no VPN) and a geo comparison; news clustered by story; a watch that returns only new results; batches; private mode. Drop-in Exa, Firecrawl and Tavily request/response formats for less than the originals. $0.004-0.05 per call; deep research (sub-questions, 16 pages, papers, news) $0.20.

## Output

A structured response containing up to 15 key extracted passages that answer the query, each with its source URL and domain, drawn from up to 8 fully-read web pages converted to clean markdown. Includes prompt-injection-checked content per page.
