Historical stock data for MSFT via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides historical stock price data for Microsoft (MSFT) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all gated behind per-request micropayments settled in USDC on the Base network.
The specific endpoint `/api/v1/stocks/MSFT/history` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (contract 0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are advertised; access is granted instantly upon payment. The payment timeout is 300 seconds.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical stock data includes (e.g., OHLCV, date ranges, granularity). The endpoint is confirmed live via a valid 402 challenge, but the actual data format and query parameters are unknown.
