Fields

Field	Type	Notes
`day`	String `String!`	The UTC day (YYYY-MM-DD).
`calls`	Int `Int!`	No further notes.
`tokensInput`	Int `Int!`	No further notes.
`tokensOutput`	Int `Int!`	No further notes.
`costUsd`	String `String!`	The day's platform-key spend — a DECIMAL STRING in USD (nano-dollar exact; the money-string law — never a float).
