Fidro + Node.js Integration

Overview

To integrate Fidro with Node.js, send a POST request to the Fidro API with the user's email and IP address. Fidro returns a risk score, email validation results, and IP intelligence data in a single JSON response. The integration requires no SDK — just standard HTTP requests using Node.js's built-in fetch API with your API key.

Fidro is a fraud detection API that combines email validation, IP intelligence, geolocation analysis, and Stripe chargeback prevention in a single API call. It returns a risk score with a clear recommendation — allow, review, or block — so you can stop fraud without building your own scoring logic.

2. Email Validation

Send a POST request to Fidro's /v1/validate endpoint with the user's email address and optional IP. Fidro validates the email, checks for disposable domains, analyzes the IP for VPN/proxy/Tor usage, and returns a risk score with a clear recommendation — allow, review, or block.

const FIDRO_API_KEY = process.env.FIDRO_API_KEY;

async function validateEmail(email, ip) {
  const response = await fetch("https://api.fidro.io/v1/validate", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${FIDRO_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({ email, ip }),
  });

  if (!response.ok) {
    throw new Error(`Fidro API error: ${response.status} ${response.statusText}`);
  }

  const result = await response.json();
  console.log("Risk score:", result.data.risk_score);
  console.log("Recommendation:", result.data.recommendation);
  return result;
}

// Usage
validateEmail("test@example.com", "8.8.8.8")
  .then((result) => console.log(result))
  .catch((err) => console.error(err));
