Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/nasdaq-private-market: open an issue to ask a question, or submit a pull request to add artifacts.

    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

  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.
