  title: Opkit API
  description: >-
    REST API for Opkit, an automated health insurance verification platform for
    telehealth companies and virtual medical practices. The API exposes
    eligibility inquiries, benefits, payers, patients, and webhooks. Requests
    are authenticated with a Bearer API key and all payloads are JSON over
    HTTPS.


    Provenance note: Opkit's platform appears to have been decommissioned after
    the company was acqui-hired by 11x in late 2024, and the live documentation
    at docs.opkit.co and the API host api.opkit.co are no longer reachable. This
    specification is reconstructed from Opkit's publicly described resource model
    (eligibility inquiries, benefits, payers, patients, webhooks; Bearer-key
    auth; base URL https://api.opkit.co/v1). Endpoint paths and object fields
    that could not be verified against live documentation are modeled
    conservatively along standard RESTful conventions and should be reconciled
    against authoritative Opkit documentation if it becomes available. No values
    are presented as guaranteed-accurate beyond the verified auth scheme and
    base URL.
