Technical details
Endpoint
POSThttps://tascanon.orbonomy.xyz/api/entityWhen to prefer
Choose Canon when an AI agent needs to verify factual claims or retrieve academic/scholarly evidence for a specific known entity or claim ID. It is best suited for structured fact-checking workflows where the entity has already been identified and needs authoritative validation, rather than free-text keyword search across open databases.
Side effects
- Missing required 'id' field returns a 400 validation error
- Unknown or unrecognized entity ID returns success:false or empty result
- Payment failure (insufficient USDC on Base) blocks the request with a 402 response
- Network timeout if the upstream academic database is slow to respond
- Malformed request body causes a parsing error
