ShortKit

ShortKit is a Y Combinator-backed short-form vertical video platform that gives product teams a drop-in, TikTok-quality video experience without the infrastructure complexity. It ships native SDKs for iOS, Android, Flutter, React Native, Expo and Web alongside a REST API for managing content, direct uploads, live streams, in-feed surveys, analytics events and ad configuration. The platform handles adaptive-bitrate HLS transcoding, global CDN delivery across 300+ points of presence, automatic caption generation with language detection, protected/signed playback, and native ad insertion (Google Ad Manager / VAST / IMA). Developer docs are partner-gated but the Mintlify API reference and the iOS SDK are published openly on GitHub.

ShortKit publishes 5 API contracts indexed on the APIs.io network, including Ad Configuration API, Analytics API, Content API, and 2 more. Tagged areas include Company, Video, Short-Form Video, Video SDK, and Streaming.

The ShortKit catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

ShortKit’s developer surface includes documentation, API reference, getting-started guide, pricing, engineering blog, signup flow, sandbox, and 21 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

8 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Operational Transparency scores 10.5 — up to +11.6 composite points
Contract Quality scores 55.3 — up to +11.2 composite points
Developer Ergonomics scores 49.4 — up to +10.1 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/shortkit/apis.yml: open an issue on github.com/api-evangelist/shortkit to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Streaming Video and Media Delivery	distribution	9.6 (thin)	-	1
Network Edge (CDN, networking, peering, edge compute)	distribution	9.6 (thin)	-	1
Accelerator Portfolios (Y Combinator, 500 Global, Antler participation)	distribution	9.6 (thin)	-	1
Official SDKs on Packagist, pub.dev and Hex	distribution	9.6 (thin)	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
