  title: Centsless Decision and Evidence Engine API
  version: 3.8.1
  description: >
    Jurisdiction-aware cash rounding compliance for point of sale.


    The engine resolves where a sale happened, finds the rule that governs it on
    that date,

    rounds the cash total by the method the rule prescribes, and seals the
    decision and its

    statutory basis into a tamper-evident hash chain.


    Amounts are integers in cents unless a field says otherwise. Timestamps are
    ISO 8601;

    send the terminal's own UTC offset. Authentication is an API key in the
    `x-api-key` header.
