# Credits & billing

> Understand how credits work and track your usage.

Lasso uses a credit-based system for extraction and enhancement operations.

## What consumes credits

| Operation                   | Credit cost                        |
| --------------------------- | ---------------------------------- |
| **Table extraction**        | Varies by file size and complexity |
| **Single cell enhancement** | \~2 credits per cell               |
| **Bulk enhancement**        | \~0.5 credits per column           |

Credit estimates are returned when you create an enhancement job, so you know the cost before processing begins.

## Checking your balance

<CodeGroup>
  ```typescript TypeScript theme={null}
  const balance = await client.credits.balance();
  console.log(`${balance.balance} credits remaining`);
  ```

  ```python Python theme={null}
  balance = client.credits.balance()
  print(f"{balance['balance']} credits remaining")
  ```
</CodeGroup>

## Tracking usage

View your credit transaction history with optional filters:

<CodeGroup>
  ```typescript TypeScript theme={null}
  const usage = await client.credits.usage({
    from: "2025-01-01T00:00:00Z",
    to: "2025-03-31T23:59:59Z",
    service: "enhancement",
  });

  console.log(`Total used: ${usage.total_used} credits`);
  ```

  ```python Python theme={null}
  usage = client.credits.usage(
      from_="2025-01-01T00:00:00Z",
      to="2025-03-31T23:59:59Z",
      service="enhancement",
  )

  print(f"Total used: {usage['total_used']} credits")
  ```
</CodeGroup>

## Insufficient credits

If you do not have enough credits for an operation, the API returns a `402` error with `error_type: "insufficient_credits"`. Check your balance before starting large enhancement jobs.
