Opkit

Opkit was a healthcare automation company that built an automated health insurance verification platform purpose-built for telehealth companies and virtual medical practices. The Opkit REST API let engineering teams run insurance eligibility checks, read benefits, look up payers, manage patients, and receive webhook events programmatically. Opkit (YC S21) later pivoted to a generative-AI healthcare call center and was acqui-hired by 11x in late 2024, after which the platform was wound down. This catalog documents the API as it was publicly described while it was operating.

Opkit publishes 5 API contracts indexed on the APIs.io network, including Benefits API, Eligibility Inquiries API, Patients API, and 2 more. Tagged areas include Healthcare, Insurance, Eligibility, Benefits, and Verification.

The Opkit catalog on APIs.io includes 1 Spectral governance ruleset.

Opkit’s developer surface includes authentication, documentation, and 8 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
