  market in pre-IPO private company equity — tender offers, company buybacks, auctions,
  block trades and a settlement engine for private share transfers — alongside a Data
  & Intelligence business built on NPM Price, a daily price estimate for 400+ liquid
  private companies, and Tape D, a private-company pricing dataset combining primary
  round data, secondary market transactions, mutual fund marks and 409A valuations.
  Securities are offered through NPM Securities, LLC (member FINRA/SIPC); SecondMarket
  Financial, LLC is an SEC-registered investment adviser and wholly owned subsidiary.
  Programmatic access to Tape D is sold on the Premium tier and distributed exclusively
  through Nasdaq Data Link; NPM itself publishes no developer portal, API reference,
  or machine-readable specification.'

  name: Nasdaq Private Market Tape D API
  description: 'Tape D is NPM''s private-company pricing and valuation dataset — real-time
    private market pricing integrating primary round data, secondary market transactions,
    mutual fund marks and 409A valuations across 4,000+ venture-backed companies. Nasdaq,
    Inc. is the exclusive distributor of the Tape D API; access is sold on NPM''s Premium
    (Talk to Sales) tier and delivered through Nasdaq Data Link''s REST API alongside
    SFTP/S3 bulk delivery. No OpenAPI, dataset/table code, or public API reference for
    Tape D is published — the "Learn about API Access" call to action on NPM''s own
    Data & Intelligence page resolves to an empty "#" anchor.'

  detail: >-
    NPM's Data & Intelligence page sells API access only on the Premium "Talk to Sales"
    tier, and its own "Learn about API Access" call to action is an empty "#" anchor —
    the Tape D API is distributed exclusively through Nasdaq Data Link, whose public
    docs index carries no Tape D dataset entry, so no reference or spec is reachable
    without a sales conversation.
