Enable Foundation Model APIs for AWS Marketplace trial workspace

[yassin]

Hello,

I created a new Databricks account through the AWS Marketplace $400 trial using my business email. The workspace is in us-east-1, the AWS Marketplace payment method is connected, and the full $400 credit balance is active.

Every Databricks-hosted Foundation Model API returns:

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

I tested both premium and open models, including:

• system.ai.databricks-gpt-5-6-luna
• system.ai.databricks-gpt-5-6-sol
• system.ai.glm-5-2

I also created a Unity Catalog model service, but it returns the same error. No custom endpoint or AI Gateway rate limits are configured.

Could you please enable a non-zero system-level Foundation Model API quota for this workspace, ideally for GPT-5.6 Luna and Sol? Please also confirm whether the workspace must be moved to a PAYABLE_VERIFIED trust tier or converted from the trial before these models can be used.

Thank you,

Yassin

That 403 with "rate limit of 0" isn't something you accidentally configured, it's a Databricks-imposed gate that applies to newly created accounts. Even with active trial credit and a valid payment method on file, Foundation Model API access gets held at zero until Databricks validates the account on their end. It's separate from the credit balance or whether you've added billing info.

The PAYABLE_VERIFIED trust tier is exactly what controls this. AWS Marketplace trial workspaces start at a lower trust level, and pay-per-token Foundation Model API access is only enabled after the account is promoted to PAYABLE_VERIFIED. That promotion isn't automatic, it typically happens within a few business days of account creation, but sometimes requires a manual bump from Databricks' side.

A few things worth checking:

1. How recently was the account created? If it's less than 24-48 hours old, waiting another day often resolves it.

2. Go to Settings > Billing in your workspace and confirm the payment method is fully attached and the trial credit shows as active. Sometimes there's a delay between when AWS Marketplace activates the subscription and when Databricks reflects the verified status.

3. If neither of those resolve it, the fastest path is to open a support ticket (or use the in-product chat) and specifically ask them to promote the workspace's trust tier to PAYABLE_VERIFIED. Mention you're on an AWS Marketplace trial and that Foundation Model API calls are returning "rate limit of 0." That's a recognized signal their support team knows how to act on.
