Pay-per-call agent tools over x402 (USDC on Base) — no signup or API key.
Call this server's tools from your browser. Nothing to install.
x402 payment authorization. No account is required: call a paid tool, receive an HTTP 402 challenge naming the price and network, settle it, then retry the same request. `initialize`, `tools/list`, and `list_premium_tools` are free. Cheapest end-to-end wiring check is the `ping` SKU at $0.001.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
