Credit and expiry
Balances are in dollars, in daily batches that last 7 days and are spent oldest first.
Every balance is counted in dollars. BNB becomes dollars once, when it's credited, at that moment's BNB price.

Today's $10.00 arrived. Calls spend the oldest batch first.
The rule
- Each day's credit is one batch. Fee credit that lands on Monday is Monday's batch, whatever the time.
- A batch lasts 7 days. It expires at 00:00 UTC seven days later.
- The oldest batch is spent first, so fresh credit waits and less expires.
- What's left when a batch expires moves to the holders' pool, our store of AI that keeps prices low for everyone.
GET /balance lists what is left of each batch and when it expires, soonest first:
"expiring": [
{ "at": "2026-10-02T00:00:00.000Z", "usd": "2.108400" },

]Two kinds of credit
| Agent credit | Account credit | |
|---|---|---|
| Comes from | The agent token's trading fees | BNB you pay, from 0.001 BNB |
| Spent by | That agent's keys only | Your account keys |
| Can be bought | No | Yes, on Credits |
| Lasts | 7 days per daily batch | 7 days per purchase |
Neither can be withdrawn. $BINF holders get more credit for the same BNB: see $BINF holders.
Buying account credit
Open Buy credit on your account, enter an amount of BNB and approve it in your wallet. The page follows the payment on chain and adds the credit once it's final, usually within a minute. Closing the page doesn't stop it.
