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.\n\nThe 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.\n\nDocumentation 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.","tags":[],"capabilities":["stock-history","historical-price-data","per-request-payment","x402-protocol","usdc-settlement","base-network","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price history","ITW stock data","Illinois Tool Works historical prices","equity price API","stock market data","historical stock quotes","x402 stock API"],"warnings":["No documentation available — docs, API, pricing, and README pages all render only a wallet-connect prompt with no technical content","No OpenAPI or JSON schema describing request parameters or response format","Endpoint is specific to ticker ITW; unclear if other tickers are supported at similar paths","No example responses available to verify data quality or schema"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/ITW/history","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/stocks/ITW/history","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and no information about supported parameters or response fields.
