Documented credit; signup eligibility unverified: $1 (period not published) (published sources disagree) per account

The billing FAQ describes a credit and account suspension after exhaustion without a payment method. Current pricing instead emphasizes prepaid credit and does not promise a signup grant; new-account eligibility remains unverified. No expiry or recurrence is stated. Credit spends at list token prices. The low account rate applies when no payment method or no credit is present.
The vendor names no country it keeps the offer from (source, read 2026-09-26).
What you send is not used to train models. In the vendor’s words: “No AI Training on Your Data: We do not use your prompts, training data, or API inputs to train or improve our AI models without your explicit opt-in.” (source).
