HTTP Status Code 429
A status code 429, also known as "Too Many Requests," is a message from a server that you've bombarded it with inquiries too quickly. It's like being told to slow down at a buffet line.
Here's a breakdown of what it means:
- What triggers it: This code pops up when a server detects you sending excessive requests in a short time frame, exceeding their set limits.
- Why it happens: Servers use rate limits to manage traffic and prevent overload. This could be due to a sudden surge in users or to protect against malicious attacks.
- The difference from a 503 error: A 503 error indicates the server itself is unavailable, while a 429 code means it's functioning but overloaded by your requests.
So, how to deal with a 429 error? The server might provide a suggested waiting time in a "Retry-After" message. Pausing for that duration and then making a fresh request is usually the solution.
