Arta imposes rate limits on API requests to maintain system stability and ensure fair usage. If you exceed these limits, the API will return a 429 Too Many Requests error. Below are the rate limits for both Live and Test modes.
Live Mode:
- Concurrent requests: 15 API calls at the same time (any type)
- Instant quote requests: 20 calls per minute
- Overall requests: 1000 API calls per minute (any type)
Test Mode:
- Concurrent requests: 10 API calls at the same time (any type)
- Instant quote requests: 10 calls per minute
- Overall requests: 500 API calls per minute (any type)
When a rate limit is exceeded, we recommend implementing retry logic with exponential backoff to handle 429 errors effectively.
