# Steply > Funnels for OpoShop stores — freeform pages published to your own storefront, order forms with order bumps, one-click offers after checkout with decline paths, split testing, and analytics taken only from real orders. This app is built on the OpoShop platform. It is agent-friendly: the full API is described in OpenAPI and wrapped by an MCP server so an LLM can drive it directly. ## Machine interfaces - API contract (OpenAPI): https://app.trysteply.com/openapi.json - API docs (Swagger): https://app.trysteply.com/docs - Fuller LLM context: https://app.trysteply.com/llms-full.txt - Release notes: https://app.trysteply.com/api/release-notes - MCP endpoint (hosted): https://app.trysteply.com/mcp — add this URL to Claude or any LLM client to drive the app in natural language. Auth with your own OpoShop store token via Authorization: Bearer . ## Auth Get an access token via POST /api/auth/login, then send it as `Authorization: Bearer ` on /api/* requests (and to the /mcp endpoint).
