  model: >-
    Multi-layered header auth. Server-to-server requests carry the merchant API
    key in the Authorization header. End-user context is established either by a
    session key (call get-session-key with x-coinflow-auth-user-id, then pass
    x-coinflow-auth-session-key; session keys last 24 hours) or by web3 wallet
    verification (x-coinflow-auth-wallet + x-coinflow-auth-blockchain, proven with
    a signature in x-coinflow-auth-signed-message and confirmed via verify-token).
    No OAuth2/OIDC.
