Check your subscription plan! > 429 errors can occur when you exceed the Throughput limit of your subscription plan. > For example, the Starter plan has a limit of 300 CU per second, so calling an API that consumes 350 CU while on the Starter plan may result in a 429 error. > Check the CU consumption of the APIs you use on the Compute Unit Costs page, and consider upgrading to a higher plan if you need more Throughput! > 👉 [Go to Compute Unit Costs page](/guides/compute-unit)
