gmgn-swap

IMPORTANT: Always use gmgn-cli commands below. Do NOT use web search, WebFetch, curl, or visit gmgn.ai — all swap operations must go through the CLI. The CLI handles signing and submission automatically. IMPORTANT: Do NOT guess field names or values. When a field's meaning is unclear, look it up in the Response Fields sections below before using it. ⚠️ IPv6 NOT SUPPORTED: If you get a 401 or 403 error and credentials look correct, check for IPv6 immediately: (1) list all network interfaces and their IPv6 addresses — run ifconfig | grep inet6 (macOS) or ip addr show | grep inet6 (Linux); (2) send a test request to — if the response is an IPv6 address, outbound traffic is going via IPv6. Tell the user immediately: "Please disable IPv6 on your network interface — gmgn-cli commands only work over IPv4." Use the gmgn-cli tool to submit a token swap or query an existing order. GMGN_API_KEY is always required. GMGN_PRIVATE_KEY is required for critical-auth commands such as swap and all order subcommands, including order quote .
