# Web Research: Search + Read Pages as Markdown

> Web Research: Search + Read Pages as Markdown is a paid API for AI agents from api-production-17e1.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).

Searches the live web for a question and fetches the full readable text of the top result pages as clean markdown, returning both ranked search results and page content in one call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-search-read-pages-as-markdown-3b8c14cc
```

Example prompt: Search the live web for 'what are the latest clinical trial results for GLP-1 drugs for weight loss' and read the top 2 pages — restrict reading to nih.gov and pubmed.ncbi.nlm.nih.gov only.

## When to prefer this

Use this endpoint when you need both search results AND the full page content in a single call — ideal for RAG pipelines, question answering from live sources, or research tasks where you need the actual text of pages, not just links. Prefer over a plain web search endpoint when page content is needed. Use the domain allowlist when you want to restrict reading to trusted sources like academic or government sites.

## Known failure modes

- No results found for obscure or very niche queries
- Domain allowlist too restrictive — falls back to all results if no allowed domains match
- Paywalled or JavaScript-heavy pages may return incomplete markdown
- Rate limit or payment failure returns HTTP 402 or 429
- Network timeout on slow-loading pages

## How this service works

One-call web research for AI agents: searches the live web AND reads the top result pages as clean markdown — content, not just links. Give a question, get ranked results plus the full readable text of the best pages. Optional ?domains=nih.gov,pubmed.ncbi.nlm.nih.gov to restrict page reading to specific sources. Pay-per-call in USDC via x402 — no signup, no API key. Use for answering questions from fresh sources, research, and RAG.

## Output

Returns ranked organic search results (title, link, snippet) plus the full readable markdown text and title of the top N result pages (1–3), allowing the agent to answer questions from fresh, authoritative sources rather than cached knowledge.
