Nasdaq Private Market
Nasdaq Private Market (NPM) operates infrastructure for the secondary 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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Nasdaq Private Market the way a machine reads it — 4 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Nasdaq Private Market scores 33.9/100 (thin), with a separate agent-readiness read of 9/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
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.
An API exists — we simply could not reach the contract without credentials or a sales conversation. This one is Nasdaq Private Market's to change: publishing the reference and a machine-readable spec at a public URL, while keeping key issuance behind whatever gate they like, would let an integrator evaluate the API before committing to a call.

How we profile Nasdaq Private Market
Each block below is one kind of artifact we hold for Nasdaq Private Market. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
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...
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Nasdaq Private Market, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
