What problem does it solve?

This Skill helps developers validate and create x402 payment configurations and endpoints, ensuring compliant and predictable payment prompts for protected resources.

Core Features & Use Cases

  • Validation: Verify v1 or v2 x402 configurations against the protocol rules and return actionable errors.
  • Creation & Normalization: Generate v2 configurations from inputs and normalize legacy v1 data to v2.
  • Debugging & Conversion: Diagnose invalid configs and convert between v1 and v2 formats for compatibility across CAIP-2 networks.
  • Use Case: Build an HTTP endpoint that returns a 402 payment requirement for a given resource and network, guiding clients to complete payment.

Quick Start

Validate a sample x402 config using the x402check SDK: pass a config object or HTTP 402 response to check() and review the result.
