Acall

Acall Inc. (アコール株式会社) is a Japanese workplace-experience software company, founded in 2010 and headquartered in Tokyo with a Kobe office, whose Acall / WorkstyleOS platform runs the physical side of hybrid work for more than 7,000 organizations. The product is a set of check-in surfaces — Acall Reception (iPad visitor reception and entry/exit records), Acall Meeting (meeting-room booking and utilization), Acall Desktop (free-address desk and workspace "spot" reservation / hoteling), Acall Gate (entry-gate integration), AI Meeting, Neat device integration and a multi-tenant building mode — stitched to Microsoft 365 and Google Calendar, Teams/Slack/Chatwork notifications, and SSO/SCIM-style provisioning. Acall publishes a REST "Acall Public API" (v1, bearer token) covering workers, facilities, events, gate access logs, spots and spot reservations, plus an outbound Webhook surface for appointment and internal-meeting events. API access is not self-serve: a token is issued only after a request through the contact form, and the API is unavailable on the multi-tenant plan.

Acall publishes 6 APIs on the APIs.io network, including Event API, Facility API, Gate API, and 3 more. Tagged areas include Workplace Management, Visitor Management, Meeting Room Booking, Desk Booking, and Hybrid Work.

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

Acall’s developer surface includes authentication, documentation, API reference, support, pricing, changelog, engineering blog, and 22 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/.
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/acall: open an issue to ask a question, or submit a pull request to add artifacts.
