SmartConvert x402

The 1st Image Optimization Engine for the Agentic Web

🌍 Official Landing Page • 📖 Swagger API Docs

Empower your AI agents with professional image conversion & programmatic M2M payments via x402.

🚀 Overview

SmartConvert x402 is a high-performance Model Context Protocol (MCP) server designed for the autonomous agent economy. It provides a plug-and-play solution for AI assistants (like Claude, Cursor, or AutoGPT) to optimize images while handling payments natively using USDC on Base.

Why it's a Game Changer:

• For AI Agents: Zero-friction image processing. No API keys to manage per user—the agent pays its own way using the x402 protocol.
• For Developers: Build apps that monetize themselves instantly. Every byte processed generates revenue directly to your wallet.
• Privacy First: High-speed processing using Sharp (Node.js) with support for WebP, AVIF, PNG, JPEG, and SVG.

🛠 MCP Capabilities

Once connected to your AI assistant, SmartConvert exposes the following tools and intelligence:

🧰 Tools

• convert_image_to_webp: High-speed conversion to WebP or AVIF. Triggers the x402 payment lifecycle automatically.

🧠 Prompts (Agentic Intelligence)

• format_advisor: An expert assistant that guides the agent on choosing between WebP (speed) or AVIF (quality) based on constraints.
• image_optimization_agent: A pre-configured system prompt to turn any LLM into an autonomous image processing master.
• x402_payment_help: Interactive guide to help users and agents understand the payment flow.

📊 Resources

• image-api://metrics: Real-time transparency on billing and usage.
• image-api://instructions: Embedded documentation for the x402 standard.
• image-api://spec: Full OpenAPI definition for deep integration.

💸 The x402 Payment Flow

SmartConvert implements the HTTP 402 Payment Required standard, specifically designed for Machine-to-Machine (M2M) communications.
