"instructions": "For API, MCP, x402, and agent-service providers, start with free GET or POST /api/service-monitor to capture a current compatibility snapshot and drift fingerprint. POST /api/managed-monitor-30d ($19 USDC) activates 30 days of hourly managed checks with durable public status. For launch/distribution work, start with GET or POST /api/provider-launch-check ($0.05), then use POST /api/agent-distribution-pack ($5) when discovery artifacts are needed. Free procurement remains at POST /api/procure. Buyer-side payment verification remains supporting infrastructure through GET /api/x402-ping, GET /api/x402-settlement-verify, and GET /api/x402-payment-preflight; POST /api/verified-resolve and POST /api/batch-verified-resolve remain available for paid live-verified decisions. A 402 is a quote, never spending authorization." }
