Endpoint
POSThttps://vert.orbonomy.xyz/api/entityWhen to prefer
Choose this endpoint when an AI agent needs to verify a factual claim or retrieve academic/research metadata against a curated knowledge base, especially within a workflow that supports x402 micropayments on Base. Prefer it over general web search when you need structured fact-checking output or scholarly source validation tied to a specific entity identifier.
