Technical details
Endpoint
POSThttps://veritas.orbonomy.xyz/api/factcheckWhen to prefer
Use this endpoint when you need multi-source fact verification of a specific textual claim or statement, especially when accuracy and cross-referencing matter. Prefer this over single-source lookup or general search when the goal is explicitly to confirm or refute a factual assertion.
Side effects
- Missing required 'query' field returns validation error
- Empty or very short query may yield low-confidence or empty claims array
- Ambiguous queries may return multiple conflicting claims
- Service unavailable or timeout results in non-success response
- Highly niche or very recent claims may have insufficient source coverage
