Checks 1–7

Regime-aware risk & rate benchmarks for on-chain AI agents on Base. Four paid x402 endpoints @ $0.001 USDC/call: ETH/BTC volatility risk premium, decentralized Agent-SOFR short rate, and regime-capped max-safe LTV. Every response carries raw inputs + an open methodology URL for audit.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
