21gram

21gram (21그램) is a South Korean pet end-of-life care company that operates pet funeral homes and an online booking and consultation platform for pet funerals. Founded in Seoul and led by Kwon Shin-gu, it began as an online brokerage letting owners find licensed pet funeral homes nationwide and book a service with 24-hour consultation, reservation and payment, then moved into operating its own facilities — acquiring Korea's first pet funeral hall, Arongi Cheonguk, in Gwangju, Gyeonggi Province — and now runs branches including Gwangju, Namyangju and Cheonan plus a large charnel house. Its consumer surface covers funeral procedures and pricing, cremation, memorial jewelry, hearse and non-attending funeral options, urns, flowers, temporary storage and scattering, and grief-support classes. It is venture-backed and trades on secondary markets. It publishes no developer program, API documentation, or machine-readable API contract; its website runs on the hosted imweb site builder.

21gram is profiled on the APIs.io network. Tagged areas include Company, Pet Care, Pet Loss, Funeral Services, and Consumer Services.

21gram’s developer surface includes support, FAQ, pricing, engineering blog, and 3 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 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/21gram: open an issue to ask a question, or submit a pull request to add artifacts.
