It is part of a broader suite of APIs offered by lowpaymentfee.com covering data analytics, AI/ML inference, finance, crypto, and utility services — all following the same pay-per-request model.\n\nThe endpoint costs $0.02 per request, settled in USDC on Base (contract 0x8335…2913). Payment is handled via the x402 X-PAYMENT header; no API keys, accounts, or rate limits are required. The x402 challenge was successfully captured with version 1, confirming the endpoint is live.\n\nThe provider's landing page lists dozens of endpoints at a uniform $0.02/request price point. Documentation pages beyond the landing page returned only a \"Connect wallet\" stub, so details about the response schema, supported query parameters, or data sources for stock prices are not available from the crawled material. The specific data source powering the RTX stock price (e.g., whether it is real-time, delayed, or end-of-day) is unknown.","tags":[],"capabilities":["stock-price-lookup","x402-payment","per-request-billing","usdc-settlement","base-network"],"categories":["finance","data"],"synonyms":["RTX stock price","Raytheon Technologies stock","stock quote API","equity price feed","real-time stock data","x402 stock API","pay-per-call stock price"],"warnings":["No documentation beyond the landing page — all doc/pricing/API pages return only 'Connect wallet' stubs.","Response schema for the stock price endpoint is not documented; actual fields are unknown.","Data source and freshness of stock price data (real-time vs. delayed) are unspecified.","Only the RTX ticker is confirmed at this URL path; availability of other tickers is not verified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/RTX/price","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/RTX/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base).
