Overview

GateCheck by LarryBuildsAI gives x402 and MCP sellers pre-listing readiness evidence before agents or buyers touch paid endpoints.

It checks public x402, OpenAPI, and MCP metadata; unpaid 402 challenge behavior; agent-readiness signals; launch-pack copy; and deterministic receipt evidence with explicit claim boundaries.

MCP endpoint: https://x402-resource-scanner.vercel.app/gatecheck/mcp Marketplace packet: https://x402-resource-scanner.vercel.app/gatecheck/marketplaces Product card: https://x402-resource-scanner.vercel.app/product-card.md

Claim boundary: GateCheck is a readiness and metadata preflight. It does not certify security, guarantee marketplace approval, prove settlement, or guarantee buyer adoption.
