What exists today
Representative families include check-ins, wallet/cards, Stripe billing helpers, business CRM endpoints, inquiries, and scan-device pairing. Most expect a logged-in business session.
What is planned
A versioned /api/v1 surface with API key headers is documented as a future contract—not something to assume is generally available yet.
Integration guidance
Prefer documented scan-device pairing for kiosks. Avoid fragile long-lived browser sessions for machine-to-machine use.
