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.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

API Evangelist profiles 21gram the way a machine reads it — 3 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — 21gram scores 9.3/100 (minimal), with a separate agent-readiness read of 3/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

No API surface

Why this profile is thin

21gram is a Korean pet funeral operator whose only digital product is a consumer booking and consultation site built on the hosted imweb site builder; its 138-URL sitemap contains no developer, API or docs page, the api./developer./docs. subdomains do not resolve, and every named /.well-known/, /openapi.json and /apis.json path 404s.

This is an honest zero, not a gap in our research. 21gram does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile 21gram

Each block below is one kind of artifact we hold for 21gram. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

Security Posture 1

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Where this information came from

This is an independent, third-party profile of 21gram, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
