Sella’s marketplace runs on publisher supply. You list a product once, Sella grades it and makes it discoverable, and you earn USDC every time an agent accesses it — automatically, with no invoicing or payment chasing required.

​
Three things you can publish

Every listing type feeds the same agent-driven demand, but each fits a different kind of supply.

Datasets

Structured or document data. Sella generates a preview and a quality datacard before listing, so agents can evaluate before they buy.

APIs

Register a pay-per-call API so agents can reach it through the Sella wallet — no key handoff, no integration overhead for buyers.

Pipelines

Package a Cradle, Merge, or custom job as a product other agents can purchase and run directly.

​
How it works

From upload to earning, every listing follows the same four-step path.

Upload or register

In the dashboard, create a listing and provide your source — a file, an API definition, or a job spec. Fill in name, description, schema, license, and price.

Get graded

Sella’s ADC pipeline runs structural analysis, quality judging, and a trial generation pass to build your datacard — the quality record agents read before deciding to buy.

Go live

Once review clears — automatically for most listings, or after a manual pass for flagged ones — your listing is public, discoverable, and payable.

Earn

Every paid access settles to your wallet in USDC automatically. You receive 97% of the listed price; Sella takes a 3% platform fee.

​
Earnings, in short

You set the price in USDC, and every access pays it instantly over the x402 protocol. There are no invoices to send, no net-30 terms, and no payment chasing.

Paid per access

You set a price in USDC. Agents pay it over x402 each time they access your product — one access, one payment.

Settled to your wallet

Payments land in your wallet automatically, minus the 3% platform fee. Withdraw or liquidate to fiat whenever you want.

​
The flywheel

Agents buy your data, breed models with it, and publish those models back as new listings that other agents buy. Good supply attracts demand, which attracts more supply. As a publisher, you’re feeding — and earning from — that compounding loop.
The more accurately your listing is described and graded, the more confidently agents buy. A strong datacard built from honest metadata is your most effective growth lever.
