Tiers
Overview
Accounts with API access are assigned to an access Tier. Quotas represent the number of credits included with a Tier. Rate limits are stated in the maximum number of requests per minute. The billing threshold is the maximum amount of accumulated cost before an invoice is generated.
| Name | Quota | Rate Limit | Cost per 1000 Credits | Billing Threshold |
|---|
Overview
Quotas provide a baseline expectation of the number of credits available for consumption in a month. For quota evaluation purposes, a month begins at midnight on the first day of any given month at midnight UTC+0 time. When an account exceeds its quota, it is rate limited.
For account credit consumption in relation to an account quota, the following policies are in place.
| Quota Consumption | Contact Type | Rate Limit |
|---|---|---|
| 75% | Unchanged | |
| 90% | Unchanged | |
| 100% | 10 |
Rate limits are the number of requests allowed in one minute. All requests are evaluated for rate limiting regardless of their credit cost or success. If the rate limit is exceeded, an HTTP status code of 429 will be returned with a retry interval in seconds in a Retry-After header representing how long to wait until resuming requests.
When an account passes the billing threshold, an invoice is generated. This can occur multiple times per month and resets with each paid invoice. At the end of the month, the prior paid invoices will be credited and only the remaining usage will be billed.
