Technical details
Endpoint
POSThttps://v0-canon.orbonomy.xyz/api/summaryWhen to prefer
Choose Canon when an agent needs to verify factual claims, explore peer-reviewed research, or produce academically grounded summaries on a topic — especially when credibility and citation-backed accuracy matter more than speed or breadth. Prefer this over general web search when the goal is fact-checking against scientific or academic literature rather than retrieving raw web content.
Side effects
- Missing required 'topic' or 'lang' fields returns a validation error
- Obscure or highly niche topics may yield thin or low-confidence summaries
- Payment failure via x402/USDC on Base blocks the request before processing
- Non-standard language codes in 'lang' may cause unexpected behavior or errors
- Ambiguous topic strings may return generalized rather than targeted summaries
