Amazon Rate Limits by Tier
What are Amazon's API rate limits?
Amazon's entry tier (AWS default quota) allows an unpublished number of requests/min and an unpublished number of tokens/min for documented default/model family. Limits scale up through Requested quota as cumulative spend and account age increase — see the full table below, verified 2026-08-15.
