Endpoint
POSThttps://veri.orbonomy.xyz/api/verifyWhen to prefer
Choose Canon when you need to verify a specific factual claim against academic or scholarly sources, especially in a multilingual context. It is well-suited for AI agents that need to ground responses in evidence, detect misinformation, or cite peer-reviewed research. Prefer it over general web search when academic credibility and structured verification results are required.
Side effects
- Missing required 'claim' field returns validation error
- Missing 'lang' field returns validation error

- Ambiguous or very short claims may produce low-confidence results
- Payment failure (insufficient USDC on Base) returns 402 error
- Highly niche or very recent claims may lack academic coverage
- Network timeout if underlying academic databases are slow
