How this service works
Real-time web search (via Exa) — ranked results with title, URL, published date, author, and relevance score for a query
Output
An ordered list of up to 10 web search results, each containing the page title, URL, published date, author name, and a relevance score indicating how well it matches the query. Results are ranked by relevance using Exa's search ranking.
Example use cases
Breaking news research assistant
“Search the web for the latest news about the US Federal Reserve interest rate decision this week — give me the top 5 results with titles, sources, dates, and relevance scores.”
Competitor intelligence gathering
“Look up recent articles about Anthropic's new product launches — I want 8 results ranked by relevance so I can see what's been published lately.”
Fact-checking a recent claim
“Search the web for information about the recent SpaceX Starship test flight results and return the top 5 ranked results with author names and publication dates so I can verify what actually happened.”
Technical details
Endpoint
GEThttps://agentx402pay.com/api/web-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, ranked web search results with rich metadata (publication date, author, relevance score) rather than just URLs. It is powered by Exa, which is particularly strong for research-oriented and semantic search. Prefer this over generic scraping endpoints when you need multiple ranked results at once with provenance metadata, and over static knowledge bases when the query requires up-to-date information from the live web.
Side effects
- Missing required 'q' query parameter returns an error
- numResults outside 1-10 range may cause a validation error
- Payment of 0.015 USDC must succeed or the request is rejected
- Very niche or obscure queries may return fewer results than requested
- Real-time coverage may be incomplete for very recent events (minutes ago)
