# Service prices and session spending

> Check per-request prices and set a spending cap for your session.

Rawchunks charges for generation, online edits, and saving voice samples. Service payments use USDC and x402. In the app, you authorize spending through **SESSION**.

## Service prices

| Action | Price per request |
| - | -: |
| Generate with **FAST** | \$0.05 |
| Generate with **STUDIO MASTER** | \$0.10 |
| **Rework**, **Layer**, **Extend**, or **Restyle** | \$0.02 |
| **Separate** stems | \$0.02 |
| **Extract** a source section | \$0.02 |
| **SAVE VOICE** from a song | \$0.05 |
| Upload a vocal reference for generation | \$0.10 |

A new vocal upload is charged separately from its generation. Saving a voice includes its preparation; there is no separate training purchase in the app.

Prices are per request. Don't assume an unsuccessful request is free or automatically refunded.

## Start a session

<Steps>
  <Step title="Connect and choose the network">
    Connect your account and choose the payment network in the header. You need enough USDC on that network for the cap you select.
  </Step>

  <Step title="Set the cap and duration">
    Open **SESSION**. Choose **$1**, **$5**, **$10**, **$25**, **$50**, or a custom amount of at least **$0.10**. Choose **1 HOUR**, **6 HOURS**, **24 HOURS**, or **7 DAYS**.
  </Step>

  <Step title="Authorize the session">
    Select **START SESSION** and review any approval or account-activation prompts. Wait for the session to become active before submitting paid work.
  </Step>
</Steps>

</Frame>

The default selection is **\$10 for 24 hours**. The cap authorizes spending; it is not an upfront purchase or subscription. A session belongs to one account and network. Switching networks does not transfer its funds or authorization.

## Check or end a session

Reopen **SESSION** to see the displayed remaining budget, limit, amount used, and expiration. Use the refresh button to retrieve the current status.

**END SESSION** revokes the session key. It does not remove an existing token approval from your wallet. Minting and buying licenses can still require separate wallet prompts.

## Selling prices are separate

Studio's **FINANCIALS** sets the prices you list for a song. It does not show the generation fee. The generation confirmation also shows those selling terms.

See [publishing and selling terms](/app/publish) for the stream rate, license price, and license allocation. Wallet transaction or account-activation costs are separate from the service prices above.
