# Pricing your Sella listings and collecting USDC earnings

> Choose a pricing tier, set a USDC price per access, and collect 97% of every settlement. The 3% platform fee is split automatically at settlement.

You set the price; Sella handles collection and settlement. Every paid access pays you in USDC automatically — there's no invoicing, no manual reconciliation, and no minimum balance required before you can withdraw. Choose a tier that fits your data's value, set a `priceUSDC`, and start earning from the first purchase.

## Tiers

Tiers signal value and buyer expectation. Pick the one that honestly reflects your listing — buyers filter by tier and price sensitivity before they ever read your datacard.

<CardGroup cols={2}>
  <Card title="free" icon="gift" href="/publishers/datasets">
    Zero cost to buyers. Great for building reputation, seeding the marketplace flywheel, or publishing open data. No payment step is required for buyers, which maximizes trial volume.
  </Card>

  <Card title="standard" icon="package" href="/publishers/datasets">
    Low-cost, high-volume access. Best for recurring pulls and datasets where price sensitivity is high and differentiation is moderate.
  </Card>

  <Card title="premium" icon="gem" href="/publishers/datasets">
    Proprietary, curated, or highly specialized data that commands a higher per-access price. Buyers expect a strong datacard and clear provenance at this tier.

  <Card title="enterprise" icon="building" href="/publishers/datasets">
    Large or custom commercial access for high-value datasets. Suited to data with significant downstream business value or unique coverage.

## Set your price

Set the `priceUSDC` field on your listing to the amount an agent pays per access. Free tier listings use `0`. Price is denominated in USDC across every supported settlement chain — buyers pay the same whether they settle on Base, Solana, or Stellar.

```json theme={null}
{
  "priceUSDC": 10.00,
  "tier": "premium"
}
```

<Tip>
  Check comparable listings using `list_datasets` sorted by `popular`. Pricing at or just below proven listings — while your [datacard](/publishers/quality) earns trust — is a reliable strategy for winning early volume before your reputation is established.
</Tip>

## The platform fee

Sella takes a **3% platform fee** on all paid accesses. The fee is split to a per-chain treasury at the moment of settlement. You receive the remaining 97% in USDC — there's nothing to invoice or reconcile on your end.

<Info>
  A **$10.00** access nets you **$9.70**. A **$50.00** access nets you **$48.50**. The fee is applied automatically at every settlement — it never appears as a separate charge or deduction from your balance after the fact.
</Info>

## How settlement works

Every paid access follows the same on-chain settlement path. You don't need to take any action between a buyer completing a purchase and your earnings appearing.

<Steps>
  <Step title="Agent pays">
    A buyer completes the [x402](/reference/x402) payment handshake for your listing's `priceUSDC` amount. The payment is initiated on-chain before the access is granted.
  </Step>

  <Step title="Sella verifies and settles">
    The payment is verified on-chain and settled through the x402 facilitator. The 3% platform fee is automatically split to the treasury at this step.
  </Step>

  <Step title="You're credited">
    Your 97% share lands in your Sella wallet in USDC, per access, in seconds. No batching, no delays, no minimum accumulation required.
  </Step>
</Steps>

## Getting paid out

Track your earnings in real time from **[Dashboard → Earnings](https://sellag.vercel.app/dashboard/earnings)**. When you're ready to move funds off-platform, you have two options.

<CardGroup cols={2}>
  <Card title="Withdraw to a wallet" icon="arrow-up-right" href="https://sellag.vercel.app/dashboard/earnings">
    Send your USDC balance to any external wallet you control. Transfers are on-chain and settle in the time of the destination network.
  </Card>

  <Card title="Liquidate to fiat" icon="banknote" href="https://sellag.vercel.app/dashboard/earnings">
    Cash out your USDC earnings through supported fiat off-ramps directly from the dashboard.
  </Card>
</CardGroup>

<Note>
  Earnings accrue per access with no minimums to start. Withdraw on your own schedule — there's no lockup period and no threshold you need to reach before funds are available.
