ADVANCE.AI Open API
eKYC building blocks — token authentication, Global Document Verification (SDK licensing, OCR field extraction, ID forgery detection), face comparison, and liveness detection with video evidence and PII data retention. All calls carry a short-lived access token in the X-ACCESS-TOKEN header and share one response envelope; HTTP is always 200 and the `code` field carries the outcome and the billing decision.
ADVANCE.AI Open API is published by ADVANCE.AI on the APIs.io network, described by a machine-readable OpenAPI specification.
Tagged areas include Identity Verification, KYC, Face Recognition, Liveness Detection, and OCR. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, authentication docs, and rate-limit docs.
This API exposes 9 operations across 9 paths, organized into 4 resource areas, and defines 8 schemas. It is described by OpenAPI 3.1.0, at version 1.0.
Requests are made against a single base URL, https://api.advance.ai.
Metadata
The identity and technical contract details declared by the specification.
Authentication & Security 1
ADVANCE.AI Open API declares
1 security scheme
for authenticating requests.
An API key is passed in the header as X-ACCESS-TOKEN (AccessToken).
By default, every request must be authenticated.
AccessToken— Short-lived access token from POST /openapi/auth/ticket/v1/generate-token. Valid for all ADVANCE.AI Open APIs and reusable until it expires.
Paths & Operations 9
Across 9 paths, the API surfaces 9 operations — 2 GET, 7 POST. They span 4 resource areas: Authentication, Document Verification, Face Comparison, Liveness Detection. Each is listed below with its method, path, parameters, and response codes.
Exchange an access key and request signature for a short-lived access token.
Global Document Verification — SDK licensing and result query with OCR and forgery detection.
Compare two face photographs and return a similarity score.
Liveness session licensing, result retrieval, video evidence and PII data retention.
Schemas 8
The contract defines 8 schemas that model the data the API accepts and returns. The most detailed are OcrFields (14 properties), LivenessResult (11 properties), Envelope (6 properties), FacePosition (6 properties). Each schema is shown below with its type and property counts.
