Tools

• agentgas_how_to_buy Moves money · ~180 tokens
  Step-by-step instructions plus the exact x402 payment URL for buying native gas for an address. This MCP server cannot sign payments; your x402 client (e.g. @x402/fetch) pays the URL with USDC on Base, gasless (EIP-3009 signature, no ETH needed).
• agentgas_order ~84 tokens
  Status of an AgentGas order by order_id: pending, processing, delivered (with payout_tx on the destination chain) or refunded (with refund_tx on Base).
• agentgas_quote ~226 tokens
  Free price quote: how much USDC (on Base, paid via gasless x402) buys a given amount of native gas (ETH on base/arbitrum/optimism, POL on polygon). Returns price_usdc, breakdown and the exact x402 URL to pay. Rejects bad input or over-capacity before any payment.
• agentgas_status ~56 tokens
  Live per-chain float, availability, prices and daily caps of the AgentGas service. Check before paying.
