Contactually

Contactually was a cloud-based CRM (customer relationship management) platform focused on helping real estate agents, brokers, and other relationship-driven professionals nurture their networks through follow-up reminders, contact bucketing, pipelines, and automated outreach. Founded around 2011, it was acquired by real estate brokerage Compass on February 27, 2019, and had already been powering Compass's own CRM. Contactually permanently ceased operations on March 31, 2022. It historically exposed a v2 REST API (api.contactually.com) documented at developers.contactually.com for contacts, buckets, notes, tasks, and webhooks, but that developer surface, the API hosts, and all SDKs are now offline. This API Evangelist profile is retained as a historical record of a defunct provider; no live API, documentation, SDK, or event surface remains to enrich.

Contactually is profiled on the APIs.io network. Tagged areas include Company, CRM, Real Estate, Contact Management, and Relationships.

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