It is part of a broader suite of pay-per-request APIs covering finance, AI/ML, data analytics, and utility services. Payment is handled via the x402 protocol using USDC on the Base network, with each request costing $0.02 (20,000 base units of USDC with 6 decimals).\n\nThe endpoint accepts POST requests and returns JSON. No API keys or account registration are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The platform advertises no rate limits and instant access. The x402 challenge was successfully captured, confirming the endpoint is live.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what parameters the POST body accepts or what fields the historical stock data response contains. The endpoint path suggests it returns historical price data for the NVDA ticker, but the exact schema, date range support, and granularity are unknown.","tags":[],"capabilities":["stock-history","historical-prices","x402-payment","usdc-base-network","pay-per-request","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["NVDA stock history","NVIDIA historical prices","stock price API","equity data endpoint","stock market data","historical stock quotes","x402 finance API"],"warnings":["No documentation available — docs, API, pricing, and README pages all return only a wallet-connect prompt with no content","No OpenAPI or JSON schema provided for request or response bodies","Request body parameters (e.g., date range, granularity) are completely unknown","This endpoint is specific to NVDA; coverage of other tickers is not confirmed at this path"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/NVDA/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/NVDA/history","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge confirms the endpoint is live and pricing is clear ($0.02/request in USDC on Base).
