SYNTHORA AgentGuard
SYNTHORA AgentGuard: pre-trade safety verdict (SAFE/CAUTION/BLOCK) for payment/DeFi agents BEFORE they transact. One signed call combines OFAC SDN sanctions screening (address + counterparty), stablecoin peg deviation in bps (DefiLlama/CoinGecko) and counterparty on-chain signal (Base: balance + tx history). Ed25519-signed attestation. Scoring only - never executes trades. POST {"address":"0x..","chain":"base","counterparty":"0x..","stablecoin":"usdc"}. 0.02 USDC on Base.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
