Foundation Models API blocked — "Databricks-set rate limit of 0" even after adding payment method

I'm trying to use the Foundation Models API (databricks-claude-opus-4-8) in my workspace but every call returns this error:

PERMISSION_DENIED: The endpoint is temporarily disabled due to a Databricks-set rate limit of 0.

This happens both from notebook code and directly in the Playground UI, so it's not an authentication issue on my end.

I already added a valid credit card to my Account Console and configured rate limits in AI Gateway (100 requests / 1M tokens per minute), but the error persists.

Has anyone run into this? Is there something I need to activate in the account beyond adding a payment method?

Any help appreciated.

Hi, this one isn't fixable from the endpoint or AI Gateway settings, even though it looks like a rate limit you should be able to just raise. That "Databricks-set rate limit of 0" is a workspace trust tier restriction, not the rate limit you configured. Trial and Free Edition workspaces get placed in a "TRIAL_VERIFIED" tier, and high-demand models like the Claude Opus family (and GPT-5.x) get blocked at that tier regardless of what you set in AI Gateway. Adding a card doesn't automatically flip that, you actually need Databricks Sales or Support to move the workspace to "PAYABLE_VERIFIED." Once that happens the 0 limit goes away on its own, no UI changes needed on your end.

If you need something working right now while that gets sorted, switch to a non-gated open model like one of the Llama endpoints, those aren't subject to this restriction.
