anonymous access, per IP and per model. With an API access key the page gives 400 requests per minute per Public Cloud project and per model, but the getting-started guide says keys from projects without a payment method (Discovery mode) cannot use the service, so that figure needs a project with a payment method. Source: the provider's page, read 2026-10-09.
In the provider's words
Anonymous access: 2 requests/min per IP per model. Authenticated (API key): 400 requests/min per project per model. Exceeding either returns HTTP 429
The catch
European provider (France), relevant for EU data-sovereignty/GDPR-conscious use. The authenticated tier needs a valid payment method on the project (though "Free" models themselves don't charge); anonymous access needs neither an account nor a card. A separate general $200 Public Cloud trial voucher also exists but is unrelated to this free-model tier
