Your account balance pays for every model call and every web search your agents make. Buy Tokens on the Billing page opens two ways to add to it.

A monthly amount

The recommended option. Choose how much AI credit lands on your balance each month with a slider; the price per unit falls as the monthly amount rises, and the screen shows the effective rate and what you save as you move it.
  • Change the quantity at any time. Billing adjusts immediately, prorated.
  • Reducing it does not take away credit you already hold.
  • Credit accumulates. It does not expire at the end of a cycle.

A one-time purchase

Fixed bundles, paid by card. $50, $100, $200 and $400 credit exactly what they cost. One does not: $300 credits $360, which is the one place in the product where a payment buys more than its face value.
Bundles are read from the payment provider’s catalogue. If it cannot be read, the screen says so and keeps the card path open rather than quietly showing nothing.

Paying with crypto

Any amount between $10 and $10,000, in USDT through Heleket.
Send the exact invoice total. A percentage buffer is added to cover conversion and the whole invoice is credited to your balance — the split is shown before you leave the page. Network fees come out of your wallet separately, so paying even slightly under the invoice can be rejected as a wrong amount.
A crypto payment confirms on-chain, which usually takes a few minutes. The panel says confirming until it settles, and you can close the page — the balance updates when the network does.

Moving money to an agent

Balance sits in your account until you push it to an agent. From the agent’s Balance panel:
  • To agent — moves account balance into that agent’s reserve and on to its provider key.
  • Back to account — reclaims what has not been spent. What the provider already spent cannot come back.
Deleting an agent reclaims its balance to the account automatically.

Reading the numbers

The total on the Billing page is the sum of the three. See How thinking is paid for.
