How this service works
Web search results (SERP). Keyless web search returning ranked title, URL, and snippet for a query — with locale/region targeting, freshness filters (past day, week, month, year), pagination, a news mode that adds publish date and source, and selectable backend engine (auto rotation, or pin Brave, Yahoo, or Yandex).
Output
A ranked list of up to 25 web search results, each containing a page title, URL, and text snippet summarizing the page content.
Example use cases
Checking latest competitor pricing updates
“Search the web for recent price changes from our top 3 competitors and summarize what you find about their current offerings and positioning.”
Finding technical solutions for error messages
“I'm getting an error that says 'CORS policy blocked the request' — search the web for explanations and common fixes, then tell me the most relevant solutions from the results.”
Researching trending industry topics
“Search the web for news and articles about generative AI adoption in healthcare from the past month, and pull out the key insights from the top results.”
Technical details
Endpoint
GEThttps://api.kadec0.xyz/v1/serpWhen to prefer
Use this endpoint when you need live, ranked web search results (SERP-style) without requiring an API key — ideal for agents that want real-time web lookup with micropayment-based access (x402). Prefer this over static knowledge bases when freshness matters or when you need URLs and snippets from the open web.
Side effects
- Missing required query parameter 'q' returns a 400 error
- num_results exceeding 25 is capped silently or returns an error
- Payment not provided or insufficient triggers a 402 Payment Required response
- Empty or ambiguous query may return zero results
- Network or upstream search provider outage causes 5xx errors
