Technical details
Endpoint
POSThttps://canon.orbonomy.xyz/api/verifyWhen to prefer
Use Canon when an AI agent needs to verify a specific factual claim or cross-reference academic sources before presenting information to users. Prefer this over general web search when you need a structured true/false or supported/unsupported verdict on a claim, especially for scientific, historical, or academic assertions. Ideal when fact-checking is a first-class requirement and you want a dedicated verification service rather than parsing raw search results.
Side effects
- Missing required 'claim' field returns validation error
- Missing required 'lang' field returns validation error
- Invalid language code may cause processing failure
- Payment failure (insufficient USDC on Base) returns 402 response
- Empty or malformed claim string may return unsuccessful result
- Network timeout for complex claims requiring deep research
