Are there any rate limits or request restrictions?

We implement fair usage rate limits to ensure optimal service for all users. Free accounts can make up to 100 requests per hour and 500 requests per day. Paid accounts have higher limits: 1500 requests per minute and no daily restrictions as long as you have available credits. If you need higher rate limits for your specific use case, please contact us to discuss a custom plan. Batch requests (up to 100 names per request) count as individual requests but are more efficient.
