declared in 1.26.0
Secure-transaction RAIL: one signed clearance before an agent sends funds. Give recipient + amount (and optionally a contract address or counterparty ERC-8004 agent id); Onyx runs the full security stack — recipient firewall, contract audit, counterparty reputation — and returns a single PASS / REVIEW / FAIL verdict + risk score, plus the Onyx take-rate quote (bps of value secured). Ed25519-signed so the clearance is provable. The check a serious agent runs before moving real money. Onyx never takes custody. (price: $0.25 USDC, tier: premium)
