CIONIC

CIONIC Inc. is a neurotechnology company in Scotts Valley, California, founded in 2018 by Jeremiah Robison, that builds "bionic clothing" for people with neurological conditions that affect walking. Its flagship product, the FDA-cleared Cionic Neural Sleeve, combines inertial and surface-EMG sensing with functional electrical stimulation to analyze gait and assist dorsiflexion in conditions such as foot drop, multiple sclerosis, stroke and cerebral palsy. Alongside the consumer device CIONIC operates a research platform — the Cionic Research Kit — offering on-body hardware, iOS and Android collection apps, a web research portal for study and protocol management, a hosted JupyterLab analysis environment, and HIPAA-compliant participant data infrastructure. The company publishes an open-source Python client and command-line tooling for that platform's REST APIs, but the API reference and machine-readable contract itself sit behind a researcher account.

CIONIC publishes 2 APIs on the APIs.io network. Tagged areas include Company, Health, Medical Devices, Wearables, and Neurotechnology.

CIONIC’s developer surface includes documentation, getting-started guide, support, engineering blog, signup flow, CLI, authentication, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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/.

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 github.com/api-evangelist/cionic: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: CIONIC runs a real, live REST platform — /a and /c services on cionic.com answer 401 to anonymous calls and an OAuth
    2.0 authorization-code flow sits in front of them — but it publishes no OpenAPI, no API reference and no /.well-known
    documents; the marketing host soft-404s every spec path to its homepage, and the only developer documentation is the company's
    own MIT-licensed Python client at github.com/cionicwear/cionic-data.
