Pricing
**$0.01 per call.** No signup, no API keys, no monthly fees.
Payment happens automatically via x402 — an open micropayment protocol. Your MCP client signs a USDC transfer on Base mainnet for each call. You need:
1. An EVM wallet private key (set as EVM_PRIVATE_KEY)
2. A small USDC balance on Base mainnet (~$1 covers 100 calls)
That's it. No accounts, no rate limits, no billing pages.

How It Works
The pip install package is a thin MCP stdio server. It proxies your tool calls to a hosted backend, automatically handling x402 payment signing. Data comes from Yahoo Finance, FRED, SEC EDGAR, and CoinGecko.
