What problem does it solve?
This Skill enables AI agents to pay for services directly over HTTP using stablecoins, eliminating the need for traditional API keys, accounts, or complex payment integrations.
Core Features & Use Cases
- Gasless Payments: Utilizes EIP-3009
transferWithAuthorizationfor USDC payments, where the client signs an off-chain authorization and a facilitator handles on-chain settlement, absorbing gas costs. - Agent-to-Agent Commerce: Facilitates autonomous workflows where agents discover, negotiate, and pay for services from other agents without human intervention.
- Use Case: An AI agent needs to summarize a document. It discovers a summarization service, checks its price ($0.01 USDC), automatically signs an authorization, and the service is delivered, with the payment settled on the Base network.
Quick Start
Use the x402 skill to call the protected API endpoint 'https://api.example.com/data' with your private key.
