Nasdaq Private Market Tape D API
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.
