Quickstart.
API key in 60 seconds.

1. Get your API key

Sign up at useveris.finance/developers. Navigate to API Keys in the developer dashboard and generate a new key. The key starts with vrs_sk_live_ for production or vrs_sk_test_ for sandbox.

• Create your account at useveris.finance/developers/signup
• Open Settings > API Keys in the dashboard
• Click Generate Key and copy the value
• Store the key in a secure location. It will not be shown again.

2. Install the SDK

Veris provides official SDKs for Python and TypeScript. Pick the one that fits your stack.

# Python
pip install veris-sdk

# TypeScript / Node.js
npm install @veris/sdk

3. Screen your first address

Pass an on-chain address and chain identifier to the screen method. The response includes sanctions match status, the matched list name, and a confidence score.

from veris import Veris
client = Veris(api_key="vrs_sk_live_...")
result = client.screen(
    address="0x7Ff9...D4eA",
    chain="ethereum"
)
print(result.status)      # "match" or "clear"
print(result.list)        # "OFAC SDN"
print(result.confidence)  # 0.998

4. Check the risk score

The risk method returns a calibrated probability from a 15-model ensemble. The response includes per-feature SHAP attribution and individual detector outputs.

risk = client.risk("0x7Ff9...D4eA", chain="ethereum")
print(risk.score)          # 0.94
print(risk.detectors)      # 7 detector outputs
print(risk.shap_values)    # per-feature attribution
