I’ve created a project, added at $10 limit, added models to the project, have a credit card on the org, created a Project key, and run a test call. The call get a 429 response insufficient quota. I’ve tried recreating everything.
Issue: It sounds like you merely “configured” instead of prepaying and funding the organization with credits.
Notes:
A project does not need models “added”. All are enabled by default without going in and editing the allowed or blocked models, of which you only have the choice of a whitelist or blacklist.
Similarly, limit is just where you will get an email for that project’s usage per calendar month.
