magent: deterministic clinical APIs for agents

magent is pay-per-request clinical ground truth for autonomous medical agents. USDC on Base. No API keys. Distinct from npm @x402/fetch (a client that pays x402 APIs). This product is the API those clients call. Same source of truth as /v1/catalog, /openapi.json, /.well-known/x402, and /llms.txt. Not a medical device.
