Technical details
Endpoint
POSThttps://v0-canon.orbonomy.xyz/api/compareWhen to prefer
Use this endpoint when you need to compare or cross-check multiple claims simultaneously — not just look up a single fact. It is specifically designed for batch claim comparison and verification against academic or authoritative sources, making it ideal for fact-checking debates, verifying competing narratives, or validating a set of assertions in one call.

- Payment failure via x402 protocol blocks request
- Malformed JSON body returns 400 error
