TooManyRequestsException class

Exception thrown when the rate limit for requests to the Horizon server is exceeded.

Horizon enforces rate limits to prevent abuse. When the limit is exceeded, this exception is thrown with a suggested retry-after delay in seconds.

Parameters:

• retryAfter: Number of seconds to wait before retrying the request

Example:

try {
  var accounts = await sdk.accounts.forSigner(signerKey).execute();
} catch (e) {
  if (e is TooManyRequestsException) {
    print('Rate limited. Retry after: ${e.retryAfter} seconds');
    await Future.delayed(Duration(seconds: e.retryAfter ?? 60));
    // Retry the request
  }
}
