Sentinel402 Paid API for AI Agents — OpenAPI Contract with x402 + MPP Payment Info
OpenAPI contract for Sentinel402 paid scanning operations, priced via x402/MPP.
About
The canonical machine-readable contract for every paid operation: OpenAPI 3.1 with x-payment-info (fixed USD prices, x402 + MPP protocols) and declared 402 responses, rendered from the same price book as the paywall itself. An unpaid request gets HTTP 402 carrying x402 and MPP challenges; pay in USDC on Base with any EVM wallet — no API key, no signup.
