Add x402 payment execution to AI agents

agent-payment-x402 is an agent skill from ECC, Affaan Mustafa's open-source agentic engineering toolkit, listed on skills.sh. It adds policy-gated payments to AI agents with the x402 HTTP payment protocol and MCP tools, with spending limits and a non-custodial wallet, to pay for APIs, services or other agents. A skill is a SKILL.md file of instructions (sometimes with scripts and reference notes) that an AI agent loads only when a task calls for it, so the agent knows the steps to follow and what to avoid. It is free and open source.
