Error code: 429 - {'error': {'message': 'exceeded quota for this month'}}

I’m bumping into an Error code: 429 - {‘error’: {‘message’: ‘exceeded quota for this month’}} that persists from l6 to l7, while we are only midway the month

This is a known, recurring issue with this specific MCP course. The lab notebooks use a shared Anthropic API key, and when too many learners hit the API in the same billing window, the shared quota gets exhausted mid-month.

It’s not something on your end to fix. A few things to try:

1. Wait and retry later (sometimes a few hours, sometimes until quota resets on the 1st of next month). The error message itself may include a Retry-After timestamp if you check the full traceback.
2. Kernel → Restart & Clear Output, then relaunch the notebook from the classroom page. Sometimes stale sessions hold onto a rate-limited state.
3. If it persists for more than a day or two, tag @Mubsi / @chris.favila or a staff member so they can look into the quota on the backend.

Others had the same issue in this course: You have reached your specified API usage limits.

Hi @Ben_Majer,

Arman is right, but a few clarifications I’d like to give:

This is not an issue, but a feature of the platform. The lab notebooks of this course come with free Anthropic API key calls. To limit abuse and over usage of this resource, each student gets a limited quota of API calls to make each month. Usually, they are enough to go through the entire course. But as students can experiment and run these notebooks many times, that threshold can be reached, as in your case.

You have to wait till August for your quota to reset.

Best,
Mubsi

Hi @aravindagn,

This is a similar case. Please wait till next month for your quota to reset.

Thanks,
