# Credits

> Learn how KonbiniAPI credits and billing work. One request equals one credit, no multipliers. Failed requests are automatically refunded.

Every API request costs **1 credit**. No multipliers, no hidden costs.

## Tracking usage

Every authenticated response includes two headers:

| Header | Description |
| - | - |
| `X-Credits-Remaining` | Credits left in your account |
| `X-Credits-Used` | Credits charged for this request (`1` or `0`) |

## Refunds

Requests that fail due to validation errors, server errors, or upstream platform issues are automatically refunded:

| Scenario | Status | Credits charged |
| - | - | - |
| Successful request | 2xx | 1 |
| Validation error | 400 | 0 |
| Server error | 5xx | 0 |
| Upstream platform error | 502 | 0 |

## Rate limits

There are no per-second or per-minute rate limits. You can make concurrent requests freely. The only limit is your credit balance — when credits reach zero, requests return `402`.

## When credits run out

If your account has no remaining credits, requests return a `402` status with the error code `credits_exhausted`. Upgrade your plan at [app.konbiniapi.com](https://app.konbiniapi.com) to continue.

## Pricing

Credits are included with monthly subscription plans. Unused credits do not roll over.

| Plan | Price/mo | Credits/mo | Per 1k credits |
| - | - | - | - |
| Free | \$0 | 100 (one-time) | — |
| Plus | \$49 | 25,000 | \$1.96 |
| Pro | \$99 | 55,000 | \$1.80 |
| Max | \$199 | 160,000 | \$1.24 |
| Ultra | \$499 | 450,000 | \$1.11 |

Credits reset each billing cycle when your subscription renews.
