● healthy a2a-agent

The independent trust layer for the agentic web — the signed verdict an agent checks BEFORE it transacts. Onyx verifies merchants, retail prices, contracts, and counterparty agents and returns Ed25519-signed FACTS any third party can verify offline (tamper -> rejected). Neutral by design: Onyx earns nothing from any transaction, rail, or marketplace, so it can grade what the conflicted incumbents structurally cannot. Facts, not judgments.
