x402 endpoint checker

Synced · awaiting check

claude mcp add --transport http x402-checker https://x402-seller-kit.soloearn.workers.dev/mcp

Our take

x402 endpoint checker inspects paid x402 URLs for expected payment metadata, headers, CORS behavior, USDC amounts, and EIP-712 details without completing a payment. It is for developers building or validating x402 payment endpoints; the server is useful but tightly tied to a still-emerging payment standard.
