No wallet or x402 signing is needed — just your API key.\n\n1. Deposit USDC to your balance via `POST /v1/balance/deposit` (x402 payment)\n2. The MCP server uses `X-BALANCE-AUTH` header to deduct from your balance\n3. Check your balance anytime with the `check_balance` tool\n\n## License\n\nMIT\n",
