How do I troubleshoot a 'Runtime Error 429'?

Troubleshooting involves several steps: 1) **Check API Documentation:** Understand the rate limits of the API you're using (requests per minute, per hour, etc.). 2) **Implement Exponential Backoff:** Retry requests with increasing delays between attempts. 3) **Reduce Request Frequency:** Optimize your code to make fewer requests. 4) **Caching:** Cache responses to reduce the number of API calls. 5) **Monitor Request Rates:** Track the number of requests your application is sending to the API to identify potential issues. 6) **Review Error Responses:** Examine the full response from the server for additional details.
