概要

What is Barcode Generator X402?

Barcode Generator X402 is an MCP server that generates barcodes in EAN-13, UPC-A, Code128, and Code39 formats, returning base64-encoded SVG images. It uses the x402 pay-per-call protocol (USDC on Base L2) with no API key, signup, or rate-limit wall. It is part of the klymax402 marketplace of micropayment APIs for AI agents.

How to use Barcode Generator X402?

Add the server URL https://barcode-generator.api.klymax402.com/mcp to your MCP client configuration (Claude Desktop, Cursor, ElizaOS, etc.). The tool utility_generate_barcode accepts data (required), and optional format, width, and height. For HTTP usage, any x402-aware client automatically handles the 402 payment challenge cycle.

No. The API is pay-per-call with no upfront registration.

What dependencies does the client need?

An x402-aware client (e.g., @x402/fetch, x402-agent-tools, or ATXP) is required for HTTP usage to automatically handle the payment challenge cycle.
