Advance Intelligence Group Authentication API

  title: ADVANCE.AI Open Authentication API
  version: '1.0'
  description: ADVANCE.AI is the digital identity verification, KYC/KYB, AML and risk management business unit of Advance Intelligence Group. Its Open API surface provides eKYC building blocks — token authentication, document verification, OCR field extraction, face comparison and liveness detection — used by 500+ enterprise clients across banking, fintech, payments and e-commerce in Southeast Asia and other emerging markets. All requests authenticate with an access token obtained from the token endpoint and passed in the `X-ACCESS-TOKEN` header. Responses share a common envelope (`code`, `message`, `data`, `transactionId`, `pricingStrategy`). Modeled by API Evangelist from the public documentation at https://doc.advance.ai — no fabricated operations.
