The Ruddr API enforces rate limits to ensure fair usage and platform stability.

​
Limits

API requests are rate limited to 20 requests per second. This limit is shared across all API keys in a workspace.

​
429 Too Many Requests

When the rate limit is exceeded, the API returns a 429 response: 
{
  "status": 429,
  "message": "Too many requests"
}

​
Retry Guidance

When you receive a 429 response, retry the request after a short delay. Use exponential backoff to avoid overwhelming the API: 
attempt 1 → wait 1s
attempt 2 → wait 2s
attempt 3 → wait 4s
attempt 4 → wait 8s
Here’s a pseudocode example: 
maxRetries = 5
baseDelay  = 1 second

for attempt = 1 to maxRetries:
    response = makeRequest()

    if response.status != 429:
        return response

    delay = baseDelay * (2 ^ (attempt - 1))
    sleep(delay)

raise "Max retries exceeded"
If you’re regularly hitting rate limits, consider reducing the concurrency of your requests or adding a small delay between calls.
