# Standalone APIs

import SnippetIntro from '/snippets/snippet-intro.mdx';

Venator provides **Standalone APIs** for direct integration into your systems.\
These APIs allow you to send data (documents, biometrics, or JSON fields) and receive **real-time structured responses**, without relying on any hosted UI or session-based flow.

<Card title="Standalone APIs" icon="server" href="document-ocr">
  Make direct server-to-server API calls. Send images, documents, or user data e.t.c  and receive structured verification results — no end-user interface required.
</Card>

Make direct server-to-server API calls. Send images, documents, or user data etc. and receive structured verification results — no end-user interface required.

## **How It Works**

<Steps>
  <Step title="Send Data">
    Your server calls a standalone endpoint (e.g., `POST /v3/id-verification/`) with the required input data such as documents, images, biometric samples, or user information.
  </Step>

  <Step title="Receive Results">
    Venator processes the request and returns a structured response based on the **specific service invoked**.
  </Step>
</Steps>

## **When to Use Standalone APIs**

Use Standalone APIs when you want to integrate Identity Fabric **directly into your own system**, without using any external dashboard or hosted verification flow.

| Use Case                     | Example                                                                                              |
| ---------------------------- | ---------------------------------------------------------------------------------------------------- |
| **Document Processing**      | Extract structured data from uploaded documents using **Document OCR** or **Document Extraction**    |
| **Biometric Verification**   | Perform identity verification using **Face Match**, **Fingerprint Match**, or **Liveness Detection** |
| **Biometric Identification** | Search and identify a person from a biometric database using **Face Search (One to Many)**           |
| **Age Verification**         | Estimate user age using **Age Estimation**                                                           |
| **Fraud Prevention**         | Detect spoofing attempts and verify genuine user presence using biometric security APIs              |

## **Available Standalone APIs**

Identity Fabric provides a wide range of standalone APIs across identity, biometrics, compliance, fraud detection, and data intelligence. Each API can be used independently based on your specific business requirements.
