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.
Example use cases
Competitive market landscape research
“Research 'best CRM software for small businesses in 2025' — read 8 pages and pull out the 15 key passages that compare features, pricing, and user reviews, with sources, focused on US results from the past month.”
Fact-checking a health claim
“I need to verify whether 'intermittent fasting improves insulin sensitivity' — can you search the web, read 8 relevant pages, and extract the 15 passages that directly address this claim with citations so I can see where the evidence comes from?”
Investment due diligence on a company
“Research 'Anthropic funding history and valuation 2024 2025' — read up to 8 full pages and give me the 15 most informative passages with their sources, pulling only results from the past year.”
Technical details
Endpoint
POSThttps://agent-search.centorprat.workers.dev/research?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
