Veqen SDKs and disposable-email data

Official Python and JavaScript/TypeScript clients for Veqen, a product of Keyveve, Inc.

Check signup risk from email, IP, phone and domain signals. Responses include a score, an admit/review/refuse verdict, and reasons. Scores are heuristic signals, not probabilities or guarantees of fraud.

Start with 1,000 free monthly credits

Create an account, verify your email, and create an API key. Keep it on your server in VEQEN_API_KEY.

Python

pip install veqen==0.1.0

from veqen import Veqen
with Veqen() as client:
    result = client.signup(email="example@mailinator.com", ip="8.8.8.8")
    print(result["risk"])

JavaScript / TypeScript

npm install https://veqen-app.com/static/sdk/veqen-sdk-0.1.0.tgz

import { Veqen } from "@veqen/sdk";
const client = new Veqen();
console.log((await client.signup({email: "example@mailinator.com", ip: "8.8.8.8"})).risk);

The Python SDK is published on PyPI; the JavaScript download works while npm publication is being completed. See Python, JavaScript, API documentation, pricing, and the free tools.

Connect an AI agent

MCP endpoint: https://veqen-app.com/mcp. Use OAuth or a Veqen API key. The official registry name is io.github.Keyveve/veqen. Connection instructions.

Compatible Agent Plugins clients and directories can import this repository: root plugin.json and mcp.json follow the Agent Plugins 1.0.0 schemas. They point to the hosted server and contain no credentials; OAuth authentication is managed by your client. Other MCP clients can connect directly to the endpoint above.

Checks spend credits (one for individual checks, three for signup checks); balance reads are free. Enabled auto top-ups can charge a saved payment method when credits run low.

Disposable-email data

data/disposable-email-domains.txt mirrors the upstream CC0 disposable-email-domains blocklist. The scheduled workflow refreshes it daily and records the upstream revision. A listed domain is a signal to investigate; it does not establish that a person is fraudulent. The API adds DNS and other context beyond this list.

Development

python -m pip install -e python pytest
cd python && python -m pytest tests
cd ../js && npm ci --ignore-scripts && npm test
