    What the data covers per plan year, every limitation, the coverage-note codes responses can carry, the event types, the screening signals and the plan-type values. Free. Also lists the prices and what isn't charged. Same data as GET /coverage of the Plan Data API.

    How this connection pays, its credit balance in dollars, each tool's price, and a link where the person can add credit by card. Call it when the person asks what's left or how to pay, or to connect another device to the same balance. Free. It returns no plan data.
