Configure x402

Overview

Configures the x402 HTTP-native payment protocol for agent-to-agent micropayments settled on Base. x402 uses the HTTP 402 "Payment Required" status code to enable pay-per-request billing — agents pay fractions of a cent per API call in USDC, with ~200ms settlement, no API keys, no accounts, and no subscriptions.

This skill supports two modes:

• Pay mode: Configure your agent to pay for MCP tool calls and external API access via x402
• Accept mode: Configure your agent as an x402 service provider that accepts micropayments for its services
• Both: Enable bidirectional x402 payments

x402 has processed 100M+ agent-to-agent transactions across 80+ ecosystem projects (Feb 2026). It eliminates API key onboarding friction and creates revenue streams from every agent interaction.

When to Use

Activate when the user says:

• "Set up x402 payments for my agent"
• "Enable pay-per-swap via x402"
