Hiver

Hiver (Hiver Inc., originally GrexIt) builds an AI-powered customer service platform for teams that run support out of shared email addresses. It ships in two forms: Hiver in Gmail, a Chrome-extension helpdesk that turns shared inboxes like support@ and billing@ into assignable, SLA-tracked queues without leaving Gmail; and Hiver Omni, a standalone omnichannel platform covering email, live chat, Slack, voice, WhatsApp, a help center and a customer portal. Hiver publishes a public REST API for Shared Inboxes, conversations, users, tags and internal notes, documented on a Theneo developer portal with a downloadable OpenAPI 3.0.2 contract, and gates API access to its Pro plan and above.

Hiver publishes 2 API contracts indexed on the APIs.io network: Conversations API and Inbox API. Tagged areas include Company, Customer Service, Help Desk, Shared Inbox, and Email.

The Hiver catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

Hiver’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, pricing, and 31 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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
Workplace Collaboration App Marketplaces	builds-on	29.6	-	-

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 3

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.
