Quarterzip

Quarterzip builds AI screenshare agents that deliver real-time, in-product user assistance. Its agent sees a user's screen, guides them by voice, and executes the steps alongside them in real time, powering onboarding, activation, and customer support at scale without additional headcount. Teams embed Quarterzip through a hosted Link URL or a client-side JavaScript SDK that launches a draggable in-app call (window.Quarterzip.open/close), and receive signed call.completed webhooks (Standard Webhooks HMAC) carrying transcripts and call ratings for CRM and analytics integration. Customers include Bloomreach, Apollo, Dovetail, Airspeed, and Zuper. Quarterzip is ISO 27001 certified.

Quarterzip is profiled on the APIs.io network. Tagged areas include Company, AI Agents, Customer-Support, Onboarding, and User Activation.

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

Quarterzip’s developer surface includes documentation, API reference, getting-started guide, signup flow, changelog, authentication, and 14 more developer resources.

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.

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/quarterzip: open an issue to ask a question, or submit a pull request to add artifacts.
