A gd-… key comes with credit in USD. Charging is by actual token usage, until the credit runs out.
The 5/7/8 inactivity rule applies to every key: reminders on day 5 and day 7, then revocation and loss of remaining credit after 8 days without use. See the exact wording in the Terms.
If the bot offers a custom package, you can enter the amount yourself. Top up an active key through API → Top up my key; the gd-… value stays the same.
- @subscribe_ai_bot → Categories → API.
- Choose an available package and payment method from the live catalog.
- The bot sends a
gd-…key and a link to the docs.
