Volt

Volt is a desktop application (Mac, Windows, and Chrome) that supercharges WhatsApp for professionals and sales teams — turning long voice notes into readable transcripts and summaries, scheduling messages, adding keyboard-first navigation, organizing chats into focused workspaces, and sending personalized broadcasts. Message content stays under WhatsApp's end-to-end encryption and never passes through Volt's own servers. For agents and AI models, Volt runs an authenticated remote Model Context Protocol (MCP) server that exposes WhatsApp contacts, chats, messages, groups, and lists as tools. Volt is backed by 500 Global, EQT Ventures, and IVP.

Volt is listed with 1 API on the APIs.io network. Tagged areas include Company, WhatsApp, Messaging, Productivity, and MCP.

Volt’s developer surface includes documentation, pricing, engineering blog, changelog, authentication, and 5 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/volt: open an issue to ask a question, or submit a pull request to add artifacts.

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
Workplace Collaboration App Marketplaces	builds-on	17.2 (thin)	-	-

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.
