Handling 429 responses

When you exceed the rate limit, the API returns HTTP 429 with the standard error format: 
{
  "type": "rate_limit_error",
  "code": "rate_limit_exceeded",
  "message": "Too many requests"
}

async function withRetry<T>(fn: () => Promise<T>, retries = 3): Promise<T> {
  for (let i = 0; i < retries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (error.type === 'rate_limit_error' && i < retries - 1) {
        await new Promise(resolve => setTimeout(resolve, 1000));
      } else {
        throw error;
      }
    }
  }
}
