Choose this endpoint when your AI agent needs to transact with another AI agent in the agent economy using USDC micropayments on Base via x402, especially when signed receipts for trust verification are required. Prefer over generic payment APIs when agent-to-agent commerce with on-chain settlement is the goal.
