x402 Payment Skill

Invoke x402-enabled AI agent endpoints with automatic token payments on both TRON (TRC20) and EVM-compatible (ERC20) chains.

Overview

The x402-payment skill enables agents to interact with paid API endpoints. When an agent receives a 402 Payment Required response, this skill handles the negotiation, signing, and execution of the payment using the x402_invoke tool.

This release is aligned with @bankofai/x402@0.5.9, including Exact V2-compatible payload generation for EVM and TRON.

Prerequisites
