// GET /relay/balance — peek at the current install's credit balance +
|
|
// tier WITHOUT charging anything. Recap clients call this to populate
|
|
// the "N credits remaining · Tier: X" banner before the user runs any
|
|
// transcribe/analyze, so the display is accurate on first load instead
|
|
// of saying "balance unknown — no relay calls yet".
|
|
//
|
|
// Same auth surface as the metered endpoints:
|
|
// X-Recap-Install-Id (required)
|
|
// Authorization (optional Bearer LIC1-... — absent = Core)
|
|
//
|
|
// Returns the standard envelope shape with result=null and
|
|
// credit_charged=0. The license-resolution path is identical to
|
|
// /relay/transcribe and /relay/analyze, so the cached online check
|
|
// against keysat happens here too — but no row mutation, no job-id
|
|
// reservation, no upstream backend call.
