2. Handle Rate Limiting (403 Forbidden)

Stack Exchange API enforces rate limits. If you exceed the allowed requests, you may receive 403 Forbidden.

✅ Fix:

• Check response headers for "X-RateLimit-Remaining". If it’s 0, you must wait before making new requests.

• Reduce request frequency or implement exponential backoff (retry with increasing delay).

Example retry mechanism with WebClient:

java

CopyEdit

response.retryWhen(Retry.backoff(3, Duration.ofSeconds(2))) .subscribe(System.out::println);
