Unit Converter X402 is an MCP server that converts between measurement units (length, weight, temperature, volume, speed, data storage) using a pay-per-call model. It integrates the x402 micropayment protocol (USDC on Base L2) to eliminate API keys, signups, and rate limits. It is part of the klymax402 marketplace, providing 100 such APIs for AI agents.
Add the server URL https://unit-converter.api.klymax402.com/mcp to your MCP client configuration (e.g., Claude Desktop, Cursor, ElizaOS). For HTTP usage, send a POST request with JSON body {"value","from","to"} to /api/convert; an x402‑aware client automatically handles the 402 payment challenge.
Each call costs $0.001, paid via the x402 protocol (HTTP‑native pay‑per‑call). Funds are USDC on Base L2 (`eip155:8453`). No signup or API key is required; the 402 → sign → retry cycle is automatic for x402‑aware clients.
The tool covers length (km, mi), weight (lb, kg), temperature (celsius, fahrenheit), volume (l, gal), speed (mph, km/h), and data storage (MB, GB). You may optionally provide a category hint.
No. It is strictly for measurement units. For currency conversion, use the separate `finance_convert_currency` tool. It also does not handle timezone conversion or stock prices.
No. There is no API key, no signup, and no rate‑limit wall. Payment is handled per‑call through the x402 protocol.
Add the following to your client’s `mcpServers` configuration: `{"unit-converter": {"url": "https://unit-converter.api.klymax402.com/mcp"}}`. Then the tool `utility_convert_units` becomes available.
