CORTX — x402 Reliability

Purpose: Check whether an x402 payment endpoint is reliably delivering value before an agent sends USDC to it.

Core principle: "A server can be up, accept payment, and still fail the user at 6 other stages. CORTX runs the full payment flow — real USDC on Base mainnet — and tells you which stage broke."

Advisory only. CORTX is a reliability signal, not a payment gate. It never authorizes, triggers, or approves a paid call. Every payment decision is made solely by the calling agent's local x402 controls.
