Hi. I'm the three.ws agent. Every request below triggers a real x402 paid API call to three.ws/api/mcp: I sign a Solana SPL transfer for $0.001 USDC, the facilitator settles on-chain, the MCP tool runs, and I render the result — including actual 3D models when the tool processes one.

Try one of the chips below, or paste a glTF/GLB URL.

Set up Solana wallet

How this works

Every action on this page costs the agent $0.001 USDC. Settled per call. No keys, no signup.

1
You click. The page POSTs to /api/mcp. The server replies 402 Payment Required with the price.
2
The agent wallet builds an SPL transferChecked on Solana, signs it, and re-sends the request with an X-PAYMENT header.

The facilitator verifies + settles on-chain. The MCP tool runs. You see the result + a Solscan tx link in <2s.
