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 APIs 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.

Opkit’s developer surface includes authentication, documentation, and 7 more developer resources.
