How this service works
Structured answer data for agents, paid per request with x402 v2
Output
A structured JSON object containing a synthesized direct answer to the submitted question, backed by up to the requested number of web result references. Agents receive a ready-to-use answer payload rather than raw search snippets, making it immediately usable in downstream reasoning or user-facing responses.
Example use cases
Real-time fact lookup for chatbot
“I need a structured answer to 'Who is the current CEO of OpenAI?' — use fast mode and give me 3 results so my chatbot can respond accurately.”
Deep research on complex policy question
“Get me a thorough, structured answer to 'What are the main provisions of the EU AI Act and when does it take effect?' using deep mode with 10 results.”
Agent answering user support question
“My agent needs to answer 'What are the symptoms of magnesium deficiency?' — fetch a structured answer in fast mode with 5 results so it can reply to the user.”
Technical details
Endpoint
POSThttps://x402.srch.best/answerWhen to prefer
Choose this endpoint when you need a synthesized, structured direct answer rather than a list of raw search result URLs. It is especially well-suited for AI agents that need to resolve a factual question in a single API call without additional parsing. Use 'deep' mode for complex or research-grade questions where synthesis quality matters more than latency. Prefer this over a raw web search endpoint when your downstream task requires an opinionated, consolidated answer rather than ranked documents.
