How this service works
Quick research: ask any question, get a concise sourced answer with key points, sources, a confidence rating, and anything that could not be verified.
Output
A structured response containing a concise answer to the research question, a list of key points, cited sources, a confidence rating indicating how well-supported the answer is, and a list of claims or details that could not be verified.
Example use cases
Fact-check a medical claim
“I heard that taking vitamin D supplements reduces COVID-19 severity — can you research that and tell me how confident we can be, with sources and anything that couldn't be verified?”
Market research for a pitch deck
“Research the current size and growth rate of the global electric vehicle battery recycling market — I need key points, sources, and a confidence rating for my investor presentation.”
Quick background on a regulatory topic
“I need a quick researched answer on whether non-compete agreements are enforceable in California — give me the key points, confidence level, and any parts that are still uncertain.”

Endpoint
POSThttps://api.lucasnode.app/api/x402/research?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, sourced, confidence-rated research answer to a specific question — especially when you want unverifiable claims flagged explicitly. It is ideal for one-shot research queries where breadth of coverage matters less than conciseness and source transparency. Prefer it over raw web search when you want synthesized key points rather than raw links, and over large LLM responses when you want explicit confidence scoring.
Side effects
- Question too vague or under 10 characters returns a validation error
- Question exceeds 500 character limit triggers schema rejection
- Context field exceeds 1000 characters causes request rejection
- Topic with no verifiable online sources may return low confidence with empty sources
- Network or upstream search failure may return an error with no answer
