Serper Rate Limits

Serper enforces rate limits at the queries-per-second (QPS) level. Limits scale with plan tier, ranging from approximately 50 QPS on the free trial up to 300 QPS on the Ultimate plan. Higher concurrency is available for Ultimate customers upon request. Credits are deducted only for successful query responses. When the credit balance reaches zero, new queries are rejected. Requesting 100 results per page (non-default) doubles credit consumption relative to the default 10-result page size.
