StatusUnknown
Output
Returns a JSON object from the fact-checking service root — likely an API index, service description, or initial fact-check result object. The exact schema is a generic object, so it may include status info, service metadata, or a direct fact-check response.
Example use cases
Verify viral social media claims
“I saw this post going around on Twitter that says 'The Great Wall of China is visible from space with the naked eye.' Can you fact-check that for me and tell me if it's actually true or just misinformation?”
Check accuracy of news articles
“I'm reading an article that claims 'Honey never spoils and has been found in ancient Egyptian tombs still edible.' Before I share this, can you verify if that's accurate or if there's something missing from that statement?”
Validate health and science claims
“My friend told me that 'You only use 10% of your brain.' I keep hearing this but it doesn't sound right. Can you fact-check whether that's true or false and explain what the actual science says?”

GEThttps://factcheck.withzero.ai/When to prefer
Use this endpoint when you need to verify claims, check factual accuracy, or detect misinformation using an AI-powered fact-checking service. Prefer this over generic web search when you want a structured true/false/uncertain verdict on a specific claim.
Side effects
- Service unavailable (5xx) if the fact-check backend is down
- Empty or minimal response if the root endpoint is just a health check
- Authentication or payment required error if the paywrap gate is enforced
- Timeout if the AI fact-checking model takes too long
- Unexpected object structure if the API schema changes
