Kittl

Kittl is a Berlin-based, browser-based graphic design platform positioned for commerce-driven creative workflows — "Canva is for content, Kittl is for commerce." It serves small business owners, Shopify and Etsy sellers, print-on-demand businesses, DTC brands, freelancers, agencies and small creative teams, covering branding, packaging, product imagery, marketing campaigns, merchandise, labels, mockups and digital assets with AI-assisted creative workflows. For developers, Kittl runs an app/extension platform: sandboxed web apps run in an isolated iframe inside the Kittl editor and integrate with editor APIs over postMessage through the official @kittl/sdk JavaScript SDK, governed by a declared scope set in manifest.json and shipped through the @kittl/cli toolchain. The platform is in beta and account approval is required to create apps.

Kittl is listed with 1 API on the APIs.io network. Tagged areas include Company, Design, Graphic Design, Creative Tools, and SDK.

Kittl’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 26 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/.

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

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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):

Contract Quality scores 7.2 — up to +23.2 composite points
Access Clarity scores 31.6 — up to +13.7 composite points
Operational Transparency scores 7.9 — up to +12.0 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/kittl/apis.yml: open an issue on github.com/api-evangelist/kittl 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
IDE Extension Marketplaces (JetBrains, VS Code, Open VSX, Docker Verified Publishers, PyPI orgs)	distribution	9.6 (thin)	-	-

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 2

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.

  name: Kittl SDK & App Platform
  description: The Kittl SDK is the bridge between a sandboxed app and the Kittl editor host. It exposes async namespaces
    — kittl.design for design operations, kittl.state for editor and app state, kittl.upload for image uploads, kittl.data
    for the font and mockup catalogs, kittl.ai for credit-metered generation, and kittl.auth for OAuth helper flows. Every
    call returns an SdkResult envelope ({ isOk, result, error }). Access is governed by a static scope set declared in manifest.json
    config.scopes and enforced by the host at call time. Apps are packaged and released through the Kittl CLI against an immutable,
    admin-reviewed version.
