Domain, Authentication & App ID

1. API Base URL

All V3 API endpoints are accessible via:

https://openapi.trustformer.info

2. Authentication

2.1 Obtaining API Key

After logging into the KYT system:

1. Navigate to Account Settings
2. Generate or view your API Key

2.2 Passing the API Key

For all API requests, include the apikey parameter in the request URL.

Example:

GET https://openapi.trustformer.info/v3/xxx?apikey=YOUR_API_KEY

2.3 Version Upgrade Notice (V2 → V3)

• V3 no longer requires the secretkey parameter.
• Only apikey authentication is required.

2.4 Authentication Error Response

If the API Key is invalid or expired, the system returns:

{
  "code": -1,
  "data": {},
  "message": "api_key is invalid"
}

3. App ID (APPID)

3.1 What is an App ID?

In the KYT Rule Engine, users can create an App.

An App represents a customized risk configuration, including:

• Risk type thresholds
• Risk Level adjustment rules
• Alert triggering logic

After creating an App, the system will display the corresponding App ID at the top of the page.

3.2 How App ID Works

When calling OPENAPI endpoints:

• If appid is NOT provided
  → The system uses the default Risk Engine configuration.

• If appid is provided
  → The Risk Engine dynamically adjusts risk evaluation results
  → Based on the user-defined Risk Threshold configuration.

This allows clients to implement personalized risk control strategies.
