Higgsfield

Higgsfield is a multi-model generative AI platform for video, image, editing, storyboarding, and commercial content creation. Its public developer API (platform.higgsfield.ai) exposes 100+ generative models — Sora 2, Veo 3.1, Kling, Seedance, Hailuo, FLUX, Nano Banana, Reve, and Higgsfield's own Soul / DoP / Popcorn models — behind a single asynchronous request/response contract: POST a model endpoint to enqueue a generation, then poll the request status or receive a webhook when it completes. The platform ships an official Python SDK (higgsfield-client), a Node.js/TypeScript SDK (@higgsfield/client), a cross-platform CLI (@higgsfield/cli), a remote MCP server (mcp.higgsfield.ai) for agent access, and a public set of Agent Skills for Claude, Cursor, and Codex. Backed by Accel and Menlo Ventures.

Higgsfield publishes 4 API contracts indexed on the APIs.io network, including Kling Video API, Minimax API, Requests API, and 1 more. Tagged areas include Company, Artificial Intelligence, Generative AI, Video Generation, and Image Generation.

The Higgsfield catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Higgsfield’s developer surface includes documentation, getting-started guide, API reference, engineering blog, support, pricing, signup flow, and 27 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):

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
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

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/higgsfield/apis.yml: open an issue on github.com/api-evangelist/higgsfield 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
Agent Skills (SKILL.md packages)	distribution	19.2 (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.
