Historical stock price data for LRCX (Lam Research) via per-request x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for the ticker LRCX (Lam Research Corporation) through the lowpaymentfee.com platform. It uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request. No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to receive data.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per call. The specific endpoint at `/api/v1/stocks/LRCX/history` accepts POST requests and returns JSON. However, the crawled documentation pages were essentially empty (showing only a "Connect wallet" prompt), so details about request parameters (e.g., date ranges, intervals) and response schema (e.g., OHLCV fields, pagination) are not documented in the available material.
The x402 challenge was successfully captured with a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base network. The endpoint is live and responding with a proper 402 challenge.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, documentation pages are effectively empty, there is no OpenAPI schema, no request/response examples, and no details on what parameters the POST body accepts or what fields the historical data response contains. The listing is functional but largely a stub.
