Vercel AI Gateway API key returns 403 Forbidden despite valid setup

Hi Vercel team,

We seem to be running into the same kind of AI Gateway 403 issue discussed in the earlier community thread: Resolving 403 Forbidden error for Vercel AI Gateway API keys

Our setup is using the OpenAI-compatible AI Gateway endpoint: https://ai-gateway.vercel.sh/v1

Requests are sent with an AI Gateway API key via Authorization: Bearer [key], and the model is routed as xai/grok-4.3.

The request is rejected with 403 Forbidden / access_denied. From the earlier thread, it sounded like some cases were caused by account/team entitlement or billing/card validation issues that had to be fixed internally by Vercel.

The project/account identifier is storypalse-7526.

Could someone from Vercel check whether this project/account has the same AI Gateway entitlement or billing validation issue? I can provide any additional team/account details privately if needed.

Thanks!
