How this service works
Deep web research for AI agents — advanced search returning the highest-relevance results with multiple query-focused snippets per source, plus an optional LLM-generated answer grounded in the returned sources when include_answer is set. One-call research assistant for high-precision queries; news and finance topics, date and domain filters.
Output
A JSON object containing the normalized query string, a timestamp of when the search was executed (UTC), and an array of ranked results — each with a title, URL, a relevant content snippet, and a numerical relevance score. Optionally includes a full cleaned page body and an LLM-generated answer grounded in results when those options are enabled.
Example use cases
Breaking news research for a briefing
“Search the web for the latest news about the EU AI Act enforcement and bring back the top results with titles, URLs, and snippets so I can write a briefing.”
Competitor monitoring for a startup
“Look up recent press coverage and announcements about OpenAI's new product releases from the past month and show me the most relevant results.”
Fact-checking a claim in real time
“Search the web for whether SpaceX successfully launched its Starship rocket this week and return what the top sources are saying.”

Endpoint
GEThttps://websearch.use.x402atlas.com/search/advanced?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, ranked web search results with relevance scores and page snippets from the open internet, especially for current events, news, or rapidly changing topics where a static knowledge base would be stale. It is ideal for AI agents that need to pay per-query without a subscription and operate on Base, Polygon, or Arbitrum using USDC micropayments via the x402 protocol. Prefer alternatives if you need bulk/batch searches, deep crawling of a specific site, or structured data extraction from known URLs.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- No payment header returns a 402 challenge with payment requirements
- Insufficient USDC balance or invalid payment signature returns a 402 rejection
- Query string exceeding 1000 characters returns a validation error
- Upstream search provider unavailability results in a 502 or 503 error
- Malformed query with no meaningful terms may return zero results
