Sensel
Sensel is a Sunnyvale, California touch-input company founded in 2013 by Ilya Rosenberg and Aaron Zarraga, building high-resolution force-sensing hardware — the Morph pressure-sensitive input device and the force-sensing touchpad technology shipped in laptops such as Lenovo's ThinkPad X1 Titanium Yoga. Its developer surface is not a web API: the Sensel API is an open-source, MIT-licensed C library (LibSensel) that talks to Sensel devices over USB/serial, published at github.com/sensel/sensel-api with C, C#, Python, Arduino, Processing, Max and Pure Data bindings and documented at guide.sensel.com. Sensel's intellectual property, physical assets and trademarks were acquired by Cirque Corporation (an Alps Alpine company), and sensel.com now 301-redirects to cirque.com/sensel.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Sensel the way a machine reads it — 4 machine-readable artifacts across 1 API, 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 — Sensel scores 17.2/100 (emerging), with a separate agent-readiness read of 5/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Why this profile is thin
Sensel's API is a local MIT-licensed C library (LibSensel) that talks to Morph/sensor hardware over USB/serial — guide.sensel.com and the sensel.h header on GitHub are fully readable by a human, but the provider publishes no OpenAPI, AsyncAPI, GraphQL SDL, Postman collection or JSON Schema anywhere, and there is no HTTP endpoint for one to describe.
The documentation is public — a person can read it, but a machine cannot. This one is Sensel's to change: publishing an OpenAPI (or AsyncAPI for events) at a stable URL would make the same surface consumable by a crawler, a linter, and an AI agent.

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 Sensel
Each block below is one kind of artifact we hold for Sensel. 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.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Sensel API (LibSensel)
The Sensel API is a C library for communicating with Sensel devices (Morph and Sensel sensor boards). It is a LOCAL DEVICE API, not an HTTP service: an application links LibSens...
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.
Sensel Plans Pricing
PLANSRate 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.

RATE LIMITSSecurity 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.

The organization behind the API
← All providers · Data indexed from github.com/api-evangelist/sensel · machine-readable index on apis.io
This is an independent, third-party profile of Sensel, 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.
