  Bargo ships one client-side embeddable component for the Congress Trades API:
  a drop-in "Congress trades" table for a single ticker, rendered entirely in
  the browser from a one-line script tag. It is distinct from the server-side
  client libraries in packages/ — it calls the public REST API directly from the
  page (which is why the API runs open CORS) and requires no key. The component
  surface below was read from the delivered loader script itself, not from
  marketing copy.

  embed_widget:
    description: >-
      A single self-initializing IIFE loader. It scans the DOM for any element
      carrying a data-congress-ticker attribute, marks it done so it is rendered
      once, and replaces its contents with a rendered table.
    loader:
      url: https://www.bargo.ai/free-apis/congress/embed.js
      tag: '<script src="https://www.bargo.ai/free-apis/congress/embed.js" async></script>'

        renders: >-
          Up to 10 most recent disclosed trades for the ticker, as a table of
          Member / Type / Amount / Date / Since, with BUY and SELL colour-coded
          and the percentage move since the trade tinted by sign.
        columns: [member, type, amount_range, transaction_date, perf_pct]
        empty_state: 'No disclosed trades found.'
        error_state: 'Could not load Congress trades.'
        initialization: 'Runs on DOMContentLoaded, or immediately if the document is already parsed.'
    theming:
      description: >-
        A light/dark base is selected first, then any individual colour may be
        overridden per element with a data attribute taking any CSS colour.
      attributes:
        - {name: data-congress-ticker, required: true, description: Stock symbol to render. Also the mount selector.}
        - {name: data-congress-theme, values: [dark, light], default: dark}
        - {name: data-congress-bg, description: Background colour.}
        - {name: data-congress-fg, description: Foreground/text colour.}
        - {name: data-congress-border, description: Border colour.}
        - {name: data-congress-muted, description: Secondary text colour.}
        - {name: data-congress-faint, description: Table header/faint text colour.}
        - {name: data-congress-buy, description: Colour for purchase rows.}
        - {name: data-congress-sell, description: Colour for sale rows.}
      defaults:
        dark: {bg: '#0d1117', fg: '#ece9e1', border: '#232b38', muted: '#9aa3b2', faint: '#5f6775', buy: '#7CFFB2', sell: '#ff6b6b'}

  note: >-
    Bargo's terms require a visible credit linking back to Bargo alongside the
    widget wherever the data is displayed publicly. The widget consumes the same
    keyless quota as any other caller, so a high-traffic page will exhaust the
    anonymous per-IP budget of the VISITOR, not the site owner.
