Rate Limits

Within each product package, we feature 4 tiers for data access. Instead of applying absolute rate limits, we limit by concurrent calls. For each product package we offer a trial tier that allows you to test and integrate the APIs with a limit of 2 concurrent calls. Once you move to production, you can flexibly choose from M (10 concurrent calls), L (20 concurrent calls), and XL (50 concurrent calls) tiers.
