# ADVANCE.AI

> ADVANCE.AI is the digital identity verification, KYC/KYB, AML, compliance and risk-management
> business unit of Advance Intelligence Group (Singapore, founded 2016). Its public Open API at
> https://api.advance.ai provides eKYC building blocks — token authentication, Global Document
> Verification with OCR and ID forgery detection, face comparison, and liveness detection with
> video evidence and programmatic PII deletion. Onboarding is sales-led; there is no self-service
> sign-up and no published pricing.

Generated by API Evangelist on 2026-09-07 from ADVANCE.AI's public documentation. ADVANCE.AI does
not publish an llms.txt of its own (/llms.txt returns 404 on advance.ai, api.advance.ai and
doc.advance.ai, probed 2026-09-07).

## Read this first

- Every response is HTTP 200. The outcome lives in the JSON envelope field `code`, never in the
  HTTP status. A client that branches on HTTP status will read every failure as a success.
- Branch on `code`, never on `message`. ADVANCE.AI states message text changes without notice.
- Billing is per response code. Each documented code is tagged `free` or `pay`. Four face-comparison
  FAILURE codes are chargeable, so blind retry of a bad image costs money each attempt.
- Every returned image and video URL expires after 24 hours.
- Two of the three product flows require a mobile SDK step. A document verification or liveness
  result cannot be produced over HTTP alone — a human must present a document or a face to a phone
  camera. Plan around this before designing an autonomous integration.

## Authentication

POST https://api.advance.ai/openapi/auth/ticket/v1/generate-token with `accessKey`, `timestamp`
(13-digit epoch ms) and `signature` = SHA256(accessKey + secretKey + timestamp). Optional
`periodSecond` sets lifetime (default 3600, min 60, max 86400). Pass the returned token on every
other call as the `X-ACCESS-TOKEN` header. One token works across all APIs and reissuing does not
invalidate an outstanding token. Keys are read from the ADVANCE.AI Websaas platform under
Account > Account Management.

## Operations

- Generate access token: POST /openapi/auth/ticket/v1/generate-token
- Document verification license: POST /intl/openapi/face-identity/document-verification/v1/auth-license
- Document verification result: POST /intl/openapi/face-identity/document-verification/v1/query
- Face comparison: POST /openapi/face-recognition/v4/check (multipart, firstImage + secondImage)
- Liveness signatureId: POST /liveness/ext/v1/generate-signature-id
- Liveness license: POST /openapi/liveness/v1/auth-license
- Liveness result: POST /openapi/liveness/v3/detection-result
- Liveness video: GET /liveness/ext/v1/get-video?livenessId=...
- Delete liveness PII: GET /liveness/ext/v1/clear-data?livenessId=...  (IRREVERSIBLE — no restore)

## Interpreting scores

- Face comparison `similarity` 0-100: above 70 pass, 55-70 manual check, below 55 reject.
- Liveness `livenessScore` 0-100: above 50 pass, below 50 manual check. When 0, `attackType` is
  1 presentation attack, 2 injection attack, 3 unsure.

## Image requirements

PNG/JPG/JPEG, under 2 MB, between 256x256 and 4096x4096. For OCR the document must be readable,
upright or landscape (not tilted ~45 degrees), unobscured, on a clean background.

## Rate limits and quotas

No numeric limit is published. Over-limit responses carry envelope code SERVICE_BUSY or RETRY_LATER
plus a `Retry-After` HTTP header (documented example: 10s). ADVANCE.AI notes SERVICE_BUSY may
migrate to HTTP 429 in future. OVER_QUERY_LIMIT means the free allocation is exhausted and is not
retryable. INSUFFICIENT_BALANCE means the account balance is exhausted.

## What ADVANCE.AI does not publish

No OpenAPI or Swagger document. No GraphQL, gRPC or AsyncAPI surface. No webhooks or events. No MCP
server. No A2A agent card. No /.well-known/ discovery document of any kind. No server-side client
library on npm, PyPI, Maven Central or any other public registry — only Android and iOS capture
SDKs from ADVANCE.AI's own endpoints. No published pricing, no self-service sign-up, no idempotency
mechanism, no reversal operation, no sandbox environment, and no dated API changelog.
