Gateway & dashboard

Ax402 is an end-to-end x402 platform. Sellers configure APIs in the control plane; buyers pay through the gateway using SDKs, the React paywall, CLI, MCP tools, or e-commerce plugins — all settled by the same facilitator.

Stack layers

  • Facilitator — verifies payment authorizations and settles on-chain (guide)
  • Control plane + gateway — multi-tenant API registry, route pricing, verify/settle middleware, reverse proxy to upstream (API reference)
  • Seller dashboard — this web app: APIs, endpoints, domains, analytics, API keys
  • SDKs — TypeScript, Go, Python control-plane clients plus buyer modules
  • Tools — ax402 CLI and MCP server for agents and CI
  • React paywall — wallet-connect overlay for SPAs
  • E-commerce plugins — WordPress, WooCommerce, Shopify starters

Traffic flow

Buyer (SDK / paywall / plugin / CLI) → gateway hostname → control plane config + facilitator verify/settle → upstream API. Unpaid requests receive HTTP 402 with payment requirements.
