The x402 CLI is a professional command-line tool that enables seamless integration with the cutting-edge x402 payment protocol for instant internet payments over HTTP. Leveraging blockchain technology, this tool allows developers to simulate, test, and facilitate Solana-based micropayments quickly and securely. The x402 CLI simplifies the process of managing permissionless stablecoin payments, ideal for monetizing APIs, pay-per-use services, or premium content with minimal friction.
What is x402 CLI?
The x402 CLI, especially through the @solwarrior/x402-cli package, is designed to interact with the Solana blockchain’s implementation of the x402 standard. It allows sending SOL token payments, verifying transaction signatures, and managing persistent CLI configurations. This tool supports Solana devnet, testnet, and mainnet-beta networks with intuitive commands and colorful, user-friendly output, making blockchain payment integration accessible even for developers new to Solana.
Features and Benefits
- Send SOL Payments: Transfer SOL tokens on Solana devnet, mainnet-beta, or testnet with ease.
- Signature Verification: Confirm transaction authenticity, payment amounts, memos, and recipient addresses.
- Configuration Management: Persistent CLI settings that you can initialize and manage with
initcommands. - Wallet Integration: Secure, file-based keypair management for development and testing purposes.
- Beautiful CLI Output: Color-coded logs and progress indicators enhance the developer experience.
- Transaction Transparency: Direct links to Solana Explorer for easy verification of payments.
- Future Enhancements: Mock API servers, agent payment workflows, and facilitator services integration are planned features.
