# Billing

Pricing for API is charged along several dimensions. All details can be found at [dune.com/pricing](https://dune.com/pricing).

<Note>
  Failed executions are charged. If you execute a query but never pull the results, you are only charged for the execution.
</Note>

## Executions

Credits are consumed based on actual compute resources used for each query execution. The performance tier you select affects credit consumption.

## Data Export

Credits are consumed when exporting query results via API or CSV.

| Plan       | Credits per MB Exported |
| ---------- | ----------------------- |
| Free       | 20                      |
| Analyst    | 10                      |
| Plus       | 2                       |
| Enterprise | Custom                  |

## Data Writes

Credits are consumed when writing data (table creation, data insertion, uploads).

| Plan       | Credits per GB Written |
| ---------- | ---------------------- |
| Free       | 3                      |
| Analyst    | 3                      |
| Plus       | 3                      |
| Enterprise | Custom                 |

<Note>
  Minimum charge is 1 credit per write operation.
</Note>

## Storage

Storage limits are per-plan caps, not charged per-credit.

| Plan       | Storage Limit |
| ---------- | ------------- |
| Free       | 100 MB        |
| Analyst    | 1 GB          |
| Plus       | 15 GB         |
| Enterprise | Unlimited     |

## Webhooks (Alerts)

| Plan       | Webhooks |
| ---------- | -------- |
| Free       | 1        |
| Analyst    | 5        |
| Plus       | 5        |
| Enterprise | Custom   |

## Queries Endpoint

Available on Plus and Enterprise plans.

## Data Transformations Billing

Data Transformations is an Enterprise-only feature with usage-based credit consumption.

### Credit Consumption

#### Compute Credits

* Same as Fluid Engine credits for query execution
* Charged based on actual compute resources used
* Depends on query complexity and execution time

#### Write Operations

* **Minimum 1 credit** per write operation
* Scales with data volume (GB written)
* Applied to INSERT, MERGE, CREATE TABLE AS SELECT, etc.

#### Maintenance Operations

* OPTIMIZE, VACUUM, and ANALYZE operations consume credits
* Based on compute resources and data written during maintenance
* Can be automated with dbt post-hooks

See [dbt Connector documentation](/api-reference/connectors/dbt/overview) for more details.
