  ThetaData's client-side / embedded surfaces. The one first-party embeddable
  component is the Theta Data Excel add-in (v3), which exposes ThetaData's
  data as Excel formula functions. There are no web components or JS element
  libraries; server-side SDKs live in packages/thetadata-packages.yml.
components:
  - family: Excel Add-in
    name: Theta Data for Excel (v3)
    platform: Microsoft Excel (Windows; macOS not currently supported — workaround is Excel on the web via Chrome)
    install: 'Excel Home ribbon -> Add-ins dropdown -> search "Theta Data"'
    requires:
      - Latest Theta Data Terminal running (talks to Terminal v3 only)
      - Standard or Pro subscription
    capabilities:
      - Formula functions for every data type, grouped in the docs sidebar (parameters + example formula per function)
      - Real-time snapshot data
    limitations:
      - No real-time streaming
      - Requests capped below Excel's 1M-row sheet limit; oversized requests return an error early
      - String parameters (symbols, dates) must be double-quoted in formulas
