Technical details
Endpoint
POSThttps://veri.orbonomy.xyz/api/compareWhen to prefer
Choose this endpoint when an AI agent needs to programmatically verify factual claims, especially against academic or scientific sources. Ideal for content pipelines that need fact-checking before publishing, research assistants that need to ground claims in evidence, or any workflow where hallucination detection or claim validation is critical. Pays per call in USDC on Base, so best suited for targeted claim verification rather than broad exploratory research.
Side effects
- Empty claims array returns validation error
- Malformed claims array fails schema validation
- Ambiguous or unfalsifiable claims may return inconclusive results
- Service unavailable if payment of 0.1 USDC on Base is not processed
- Rate limiting if too many claims submitted simultaneously
- Very niche or highly specialized claims may lack academic coverage
