Uthana

Uthana builds foundation models for human motion — generative AI that creates lifelike 3D character animation from text prompts, 2D reference video, or real-time input, instantly retargeted to any rig (with auto-rigging for unrigged characters). Founded in 2023, Uthana exposes its platform through a GraphQL API at uthana.com/graphql with official Python and JavaScript/TypeScript clients, React hooks, Blender and Maya plugins, ComfyUI nodes, and REST endpoints for downloading motions in FBX, GLB, BVH, and Unitree G1 CSV formats for games, film, AI-native platforms, and robotics.

Uthana is listed with 2 APIs on the APIs.io network. Tagged areas include Animation, 3D Characters, Generative AI, Motion Capture, and Gaming.

Uthana’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, FAQ, pricing, and 29 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics 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):

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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

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 35.1 — up to +16.2 composite points
Contract Governance scores 4.5 — up to +11.5 composite points
Operational Transparency scores 26.3 — up to +9.6 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/uthana/apis.yml: open an issue on github.com/api-evangelist/uthana to ask a question or point us at an artifact you publish.
