Introduction

Welcome to soft.house - the developer portal for building AI-native commerce applications.

What is soft.house?

soft.house is the developer portal for the Pragma.Vision ecosystem. We provide APIs, SDKs, and tools to help you build AI-native commerce applications that work with Google, OpenAI, and other AI assistants.

Our platform enables agents to discover products, negotiate prices, authorize payments, and fulfill orders — all through standardized protocols.

Multi-Protocol Support

Our unified API supports multiple protocols, giving you flexibility in how you integrate AI commerce:

Key Features

  • Protocol Auto-Detection — We automatically select the best protocol for each request
  • 69% Code Sharing — Our unified architecture means consistent behavior across protocols
  • Type-Safe SDKs — Full TypeScript definitions with autocomplete support
  • Real-time Updates — Webhook support for wish status changes
  • Secure by Default — ECDSA signatures, nonce validation, rate limiting

Architecture Overview

soft.house is built on a three-layer protocol architecture:

  1. Identity Layer (TAP) — Verifies that agents are legitimate
  2. Authorization Layer (AP2) — Proves user consent for spending
  3. Execution Layer (ACP + x402) — Processes the actual payment

This separation ensures each layer can be independently verified and upgraded.
