- Remote SSE MCP endpoint at currency-converter.api.klymax402.com/mcp
- x402 micropayment gate on the hosted API (pay-per-use, no local server required)
- Server schema version 1.1.0 with published GitHub source
- Agent-callable conversion without building your own rate-ingestion pipeline
- MCP server version 1.1.0
- Single remote SSE endpoint (hosted MCP, not local stdio)
- x402 micropayment on API calls
What problem does it solve?
You need trustworthy FX and crypto prices inside the agent without juggling ECB feeds, CoinGecko keys, and cron jobs.
Who is it for?
