Error Code 429 from TruecallerJS: What It Means and How to Fix It

How to Fix Error Code 429 from TruecallerJS

Don’t worry, fixing error code 429 from TruecallerJS is easier than you think! Here are some step-by-step solutions to get you back on track:

Solution 1: Rate Limiting

TruecallerJS has a rate limit on the number of requests you can make within a certain time frame. To avoid hitting this limit, implement rate limiting in your application:

const requestInterval = 1000; // 1 second
let lastRequestTime = 0;

function searchPhoneNumber(phoneNumber) {
  const currentTime = new Date().getTime();
  if (currentTime - lastRequestTime < requestInterval) {
    console.log("Rate limit exceeded. Waiting for 1 second...");
    setTimeout(() => {
      searchPhoneNumber(phoneNumber);
    }, requestInterval);
  } else {
    // Make the TruecallerJS API request
    lastRequestTime = currentTime;
  }
}

Solution 2: API Key Validation

Ensure your API key is valid and hasn’t reached its request limit:

Contact TruecallerJS support to verify your API key and request limits. If your API key is invalid, request a new one or renew your subscription.

Solution 3: IP Address Change

If you’re using a shared hosting or VPN, try changing your IP address:

Contact your hosting provider or VPN service to request a new IP address. This might resolve the issue, especially if TruecallerJS has blocked your previous IP address.

Solution 4: Server-Side Cache

Implement server-side caching to reduce the number of requests to TruecallerJS:

const cache = require("node-cache");

const cacheTTL = 3600; // 1 hour

async function searchPhoneNumber(phoneNumber) {
  const cachedResponse = cache.get(phoneNumber);
  if (cachedResponse) {
    return cachedResponse;
  }

  // Make the TruecallerJS API request
  const response = await axios.get(`https://api.truecaller.com/search/${phoneNumber}`);

  cache.set(phoneNumber, response.data, cacheTTL);

  return response.data;
}
