Historical stock data for HON (Honeywell) via x402 micropayment on Base, $0.02/request.
What it does
This endpoint provides historical stock price data for the ticker HON (Honeywell International) 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 pay-per-call APIs offered by lowpaymentfee.com spanning finance, AI/ML, data analytics, and utility services, all priced uniformly at $0.02 per request. The specific endpoint at `/api/v1/stocks/HON/history` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02.
Documentation beyond the landing page is sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of query parameters or response fields. The URL pattern suggests the API may support other stock tickers by substituting the symbol in the path, but this is unconfirmed.
