Historical stock data for ITW (Illinois Tool Works) via per-request x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for the ticker ITW (Illinois Tool Works) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI/ML, and infrastructure utilities. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.
The endpoint is live and returns a standard x402 challenge (HTTP 402) when called without payment. It accepts POST requests and returns JSON. No API keys or accounts are required — callers simply attach an x402 payment header with each request. The platform advertises no rate limits and instant access.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no description of request parameters (e.g., date ranges, intervals), and no example responses. The specific data fields returned by the /stocks/ITW/history endpoint are unknown from the available material. The endpoint path suggests it returns historical price data for the ITW stock ticker, but the exact schema, supported query parameters, and data granularity cannot be confirmed.
