HyperVerge KYC OCR API

openapi: 3.0.3
info:
  title: HyperVerge Identity Verification API
  description: >-
    HyperVerge is an AI-based identity verification and customer onboarding
    platform. This document models HyperVerge's documented public REST surface
    for India, drawn from HyperVerge's official REST-API documentation
    repositories on GitHub. The surface spans three region hosts:


      * `https://ind-docs.hyperverge.co/v2.0` - KYC document OCR / extraction.

      * `https://ind-verify.hyperverge.co` - central database verification,
        input validation, and field matching.

      * `https://ind-faceid.hyperverge.co` - face match.


    All requests authenticate with an `appId` and `appKey` pair issued by the
    HyperVerge team (headers are lowercase `appid`/`appkey` on the Face Match
    host). Credentials are provided after enterprise onboarding. Region hosts
    exist for other geographies (for example `apac.faceid.hyperverge.co` for
    Face Match in APAC); only the India hosts are modeled here.


    Scope note: endpoint paths, methods, and auth are grounded in HyperVerge's
    published REST documentation. Request/response schemas are modeled
    representatively (multipart form-data and JSON bodies) rather than copied
    field-for-field, and are flagged where they are approximate. Liveness
    detection is delivered via HyperVerge's SDKs/Workflow and is not modeled as
    a REST operation here because a standalone public REST endpoint was not
    confirmed at review time.

    verbatim contracts.
