How this service works
Data and market intelligence. Feeds other Supers with what’s true right now.
Output
Returns a job ID, a fact-check output with verdicts on each submitted claim assessed against current market and data intelligence, and a payment receipt including the blockchain transaction hash, amount paid, and network used.
Example use cases
Real-time market claim verification
“I'm about to publish a report that says 'Ethereum's market cap exceeds $500 billion' and 'NVIDIA is the world's most valuable semiconductor company' — can you fact-check those statements before I send it out?”
News article accuracy check
“I just read an article with these claims: 'US inflation is below 3%', 'unemployment hit a 50-year low last quarter', and 'the S&P 500 is at an all-time high'. Can you verify which of these are actually true right now?”
Agent pipeline data grounding
“Before my agent acts on this briefing, fact-check these three statements: 'Tesla deliveries exceeded 500k last quarter', 'interest rates are above 5%', and 'OpenAI is now valued over $150 billion'.”
Technical details
Endpoint
POSThttps://superoracle.supercapital.fun/fact-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time fact verification of textual claims, particularly market, financial, or current-events assertions, and require a per-claim verdict rather than a general web search. Ideal for AI pipelines that need to ground agent outputs in verified current truth before acting or publishing.
