Fair 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, and the QC limit is the included number of query channel API calls per month. Message storage and channel storage are the cumulative records retained on the platform, and bandwidth is the monthly egress allowance.
| Band | Chat annual spend | API limit | QC limit | Message storage | Channel storage | Outbound traffic - Chat API & Webhooks / month |
|---|---|---|---|---|---|---|
| 1 | $0-$6K | 2M | 200K | 5M | 500K | 500 GB |
| 2 | $6K-$15K | 10M | 1M | 10M | 1M | 500 GB |
| 3 | $15K-$25K | 20M | 2M | 20M | 2M | 500 GB |
| 4 | $25K-$50K | 100M | 10M | 35M | 3.5M | 750 GB |
| 5 | $50K-$100K | 200M | 20M | 50M | 5M | 1 TB |
| 6 | $100K-$200K | 500M | 50M | 75M | 7.5M | 2 TB |
| 7 | $200K-$300K | 1B | 100M | 100M | 10M | 3 TB |
| 8 | $300K-$500K | Custom | Custom | 200M | 20M | 4 TB |
| 9 | $500K+ | Custom | Custom | 500M | 50M | 5 TB |
Overage pricing
Overages are billed independently for each resource. You only pay for the resource that exceeds its included allowance.
| Resource | Overage rate |
|---|---|
| Stored messages | $5.00 per 1M |
| Stored channels | $100.00 per 1M |
| Outbound traffic - Chat API & Webhooks | $0.40 per GB |
| Total API calls | $7 per million |
| Total query channel API calls | $2.50 per 100,000 |
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.
