Greyter

Greyter Water Systems Inc. was an Ontario, Canada manufacturer of onsite greywater recycling and water reuse systems, founded in 2012 after acquiring the assets of the defunct Brac Systems. Its flagship Greyter HOME captured water from showers and bathtubs, treated it, and returned clear, odor-free water for toilet flushing, cutting a family home's indoor water consumption by up to 25 percent; it earned NSF/ANSI 350 Class R certification in early 2019 as the first compact residential greywater reuse system to hold that designation. A scaled commercial line served water harvesting and reuse for toilet flushing and cooling towers in multi-unit and institutional buildings, and the systems were installed in more than a dozen countries. The company raised roughly $13M through a Series B. Its only software was an end-user monitoring surface — the mygreyter.com portal and a consumer Greyter mobile app used by owners to watch water savings — and it never published a developer program, public API, SDK, webhooks, or any machine-readable specification. Greyter Water Systems Inc. filed for bankruptcy on January 8, 2026, with GlassRatner Restructuring Inc. appointed Trustee and its intellectual property, patents and customer lists placed into an asset sale process. This profile is retained as a historical record; there is no API surface to enrich.

Greyter is profiled on the APIs.io network. Tagged areas include Company, Defunct, Water, Water Recycling, and Greywater.

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

x-domain-note: 'greyter.com is no longer operated by the company. It is a GoDaddy parked domain (ns71/ns72.domaincontrol.com):
  every path — including /openapi.json, /graphql, /mcp and every /.well-known/* location — returns the identical 114-byte
  HTML stub that redirects to /lander, and sitemap.xml lists only /lander. The /robots.txt and /llms.txt served there are
  GoDaddy parking-lander boilerplate, not provider-published documents, and are deliberately NOT wired as pointers. The last
  live archived snapshot of the real site is 2026-06-08. mygreyter.com, the customer portal, still resolves through Cloudflare
  but its origin is dead (HTTP 526).'
x-harvest-note: The inherited stub carried a Website pointer to https://www.nasdaqprivatemarket.com/, which is the secondary-market
  harvest SOURCE and not this company's website. It was a misattribution and has been removed.
