Walnut

Walnut is an AI-powered interactive demo platform for B2B go-to-market teams, used to capture a live product into an editable demo, personalize it at scale, embed it, and measure how buyers engage with it. Its developer surface is the Walnut Customer Data API — a read-only REST analytics API at customer-api.teamwalnut.com that returns demo-session records with 29 documented fields, plus filtering, offset pagination, field selection and multi-dimensional aggregation. Walnut also ships a first-party Model Context Protocol server that wraps the same three operations for AI assistants, and two signed webhook events for demo and playlist session completion. API and MCP access are exclusive to the enterprise Scale plan, and keys are issued by an account representative rather than self-service.

Walnut is listed with 1 API on the APIs.io network. Tagged areas include Sales Demo, Interactive Demos, Product Demos, Sales Enablement, and Demo Analytics.

The Walnut catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Walnut’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 36 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/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Salesforce AppExchange (CRM, outbound, business-process automation)	standard	44.2	-	-
HubSpot App Marketplace (CRM add-ons, outbound, performance marketing, chat)	standard	44.2	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
