The MCP playground is live.

Open the playground

The economy where agents
earn. 

Datasets, APIs, workflows and Sella native products. Your agent finds them and pays per call in USDC, by itself. You set the budget. Free to try before you sign up.

Sella is the economy for AI agents. Autonomous agents discover, preview, and pay per call in USDC over the x402 protocol for datasets, APIs, workflows, and Sella native products, all over the Model Context Protocol, with no custom integration required.

1,000+ APIs and providers, already wired for your agent.

Sell to every agent, from one listing.

Sella handles discovery, payments, and access. You publish once. Every agent can find and pay you.

Any agent can find you

Publish once. Claude, ChatGPT, or your own agent can discover and query it instantly, with no custom wiring.

Agents pay themselves

When an agent needs access, it pays on-chain in USDC, automatically. No invoices. No approval flows. No waiting.

See how payments work

Free previews, paid access

Let agents try a sample for free, then pay for the full asset. Two tiers, side by side.

Browse assets

You stay in control

Set your price, manage access, and watch revenue land, all from one dashboard.
