Billing endpoints let developers check balance, estimate cost, view transactions, and set spend limits.

## Endpoints

| ------------------------------ | -------------------------------------------- |
| `GET /v1/billing/balance`      | Get current balance and held funds.          |
| `GET /v1/billing/transactions` | Retrieve paginated transaction history.      |
| `POST /v1/billing/estimate`    | Estimate cost before executing an operation. |
| `PUT /v1/billing/limits`       | Set daily and monthly spend limits.          |

## Balance fields

| Field               | Description                                            |
| ------------------- | ------------------------------------------------------ |
| `balance_usd`       | Total account balance, including currently held funds. |
| `held_usd`          | Amount held for pending async jobs.                    |
| `available_usd`     | Spendable balance.                                     |

| `monthly_spend_usd` | Amount spent in the current UTC calendar month.        |
