Days Between API for agents
Whole days between two ISO dates. Call when you compute agent SLA windows or age. Returns days and ok for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
