Facing 429 on Billing Account

Hi I am constantly facing 429 errors when calling the Pro models, even though I have activated billing.

I am very confused as to where to check for my API rate limits/account tier due to the rebranding of Vertex AI/AI studio to the agent platform. Please help!

Ensure you have a low cap in place, this doesn’t work well at all and the 429 errors have caused my cap to be exceeded on multiple occasions without warning.
