UniverseThemesResponse

available
Type: boolean
required

Whether the caller's tier may restrict a scan universe by theme. False for free/expired/anonymous callers, and themes is then empty — the two are reported separately so a client can tell 'upgrade to use this' from 'this week's classification produced nothing'.
themes
Type: array object[] · UniverseTheme[]
required

This week's scannable themes. Empty when the caller's tier is not entitled, or when the upstream classification run produced none.
- label
  Type: string
  required
  
  The theme name, and the exact string that goes in Universe.Theme.
- ticker_count
  Type: number
  required
  
  Securities this theme contributes to a scan universe: core + satellite assignments. NOT num_tickers from /api/v2/stocks/themes, which is core-only — expect the two to differ.
- color
  Type: string
  
  Stable hex colour, inherited across runs where membership persists — the same colour the theme performance charts use. Optional.
- short_label
  Type: string
  
  Abbreviated name for dense/small-screen contexts. Absent on classification runs predating the field, so always fall back to label.
