Affinity Solutions

Affinity Solutions is a New York consumer purchase data and insights company that licenses bank-direct, permissioned credit and debit card transaction data covering 100M+ consumers and tens of billions of annual purchases. Its Comet platform turns that transaction feed into Consumer Purchase Insights, Consumer Purchase Lift, Consumer Purchase Audiences, Card-Linked Engagement and Consumer Bank Campaigns products for brands, media owners, retail and QSR, financial services and investors. Data is delivered through data clean rooms (AWS Clean Rooms), a Snowflake Native App on Snowflake Marketplace, managed services and aggregated-insight APIs rather than a public self-serve developer portal; no public API reference, OpenAPI description or SDK is published. The one machine-readable surface the company serves anonymously is an OAuth-protected Model Context Protocol server on its marketing site.

Affinity Solutions publishes 1 API on the APIs.io network. Tagged areas include Company, Data, Analytics, Consumer Purchase Data, and Transaction Data.

Affinity Solutions’ developer surface includes engineering blog, authentication, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/affinity-solutions: open an issue to ask a question, or submit a pull request to add artifacts.

  description: An OAuth-protected Model Context Protocol server that Affinity Solutions serves from its own corporate site
    at www.affinity.solutions, advertised by an RFC 8414 authorization-server document and an RFC 9728 protected-resource
    document. Two MCP endpoints are registered under the site's WordPress REST namespace; both return HTTP 401 to an anonymous
    tools/list, so the live tool set and input schemas require an authenticated OAuth introspection. This is a site/content
    MCP surface, not the Comet consumer purchase data product, which is licensed through clean rooms and Snowflake.
