RESTFair Usage Limits
Stream applies fair-usage limits to API calls and query channel processing on every Chat plan. Your plan band determines the included allowances, and usage above these thresholds is billed as an overage (see Overage pricing below).
Included fair-usage limits by plan
The API limit is the total number of API calls included per month. The QC limit is the included number of query channel API calls per month.
| Band | ACV range | API limit | QC limit |
|---|---|---|---|
| $0-$5K | $0-$5K | 2M | 200K |
| $5K-$12K | $5K-$12K | 10M | 1M |
| $12K-$25K | $12K-$25K | 20M | 2M |
| $25K-$50K | $25K-$50K | 100M | 10M |
| $50K-$100K | $50K-$100K | 200M | 20M |
| $100K-$199K | $100K-$199K | 500M | 50M |
| $200K-$299K | $200K-$299K | 1.00B | 100M |
| $300K+ | $300K+ | Custom | Custom |

Overages are billed independently for each resource. You only pay for the resource that exceeds its included allowance.

If you are seeing unexpected overage charges, the fastest path to a fix is to review the common causes of overages and apply the cost-reduction levers on the Storage and Bandwidth page. Reach out to your account team if you want help auditing your traffic patterns.
