Zentaras AI API

The Zentaras API is organized around REST. Predictable resource-oriented URLs, JSON-encoded responses, conventional HTTP response codes, and standard authentication. Verify identities in 195+ countries with a single, unified interface.

Quickstart

Create your first verification in under 60 seconds. Generate an API key from the dashboard, then issue your first request.

curl -X POST https://api.zentaras.online/v1/verifications \
  -H "Authorization: Bearer sk_live_xxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "kyc",
    "applicant": {
      "first_name": "Aarav",
      "last_name": "Sharma",
      "dob": "1995-04-12",
      "country": "IN"
    },
    "checks": ["document", "face_match", "liveness", "aml"]
  }'

Response

A successful request returns a verification object with check results and a risk score (0–100, lower is safer).

Authentication

Authenticate using your secret API key in the Authorization header. Keep keys secret — never expose them in client-side code or public repositories.
