Configure your agent (MCP)

Add to your MCP client config:

{
  "mcpServers": {
    "teos": {
      "command": "npx",
      "args": ["-y", "@teos/agent-tools"],
      "env": { "TEOS_BASE_URL": "https://teos.144.202.19.248.sslip.io" }
    }
  }
}

How payment works

  1. The agent calls a tool → TEOS responds HTTP 402 with machine-readable payment terms.

  2. An x402-capable client signs a USDC payment and retries with the payment header.

  3. The facilitator verifies and settles → the tool returns JSON.

Accepted rails: Solana, Base, Polygon (USDC). Facilitator: https://facilitator.payai.network.

    Near-term paid hop: JSON Schema draft/validate (transform.json_schema ≈ $0.02; unpaid tools/call → HTTP 402, x402 USDC on Base). Receipt→JSON (parse.receipt ≈ $0.10) remains demo/depth. Discover tools free via tools/list; pay per tools/call with x402 USDC on Base (default). Prepaid fiat packs closed; existing balances still debit. Fail-closed.
