Programmatic QR Code Generation with Developer APIs & MCP

Integrating fast QR code generation into your web apps, microservices, and AI workflows shouldn't require bloated backend libraries or vendor lock-in. The EZ QR Generator API provides a high-speed edge endpoint to generate static QR codes programmatically.

REST & Agentic Integration Architecture

  • REST Endpoints (GET & POST /a2a/generate): Simple HTTP query and JSON payloads returning raw SVGs, PNG binary data, or base64 JSON responses.
  • Model Context Protocol (POST /mcp): Native MCP tool definition (generate_qr_code) enabling autonomous AI agents (Claude, Cursor, LangChain) to call QR generation functions.
  • x402 Micropayment Protocol: Automated HTTP 402 payment negotiation ($0.001 USDC) for programmatic vector downloads and custom brand styling without monthly SaaS subscriptions.

Quick Curl Implementation Example

curl -X POST https://ez-qr-generator.com/a2a/generate \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "format": "svg", "dotStyle": "circle"}'
