X402 Paywall Agent
Detects and pays x402 crypto paywalls automatically to give AI agents seamless access to premium content and APIs.
The X402 Paywall Agent is a specialized skill for Claude Code that enables AI agents to handle HTTP 402 'Payment Required' responses autonomously. It parses payment requirements from response headers, verifies them against user-defined spending policies, and executes USDC transactions on the Base network using EIP-3009 authorizations. This skill transforms the standard fetch process into a payment-aware utility, allowing agents to access gated data, premium APIs, and specialized services without manual user intervention while maintaining rigorous security and budget controls through per-request caps and daily spending limits.
