It is part of a broader platform offering data, analytics, AI, finance, and utility endpoints, all priced at $0.02 per call with no API keys, no rate limits, and no commitments. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).\n\nThe x402 challenge confirms the endpoint is live, accepting POST requests and requiring an X-PAYMENT header. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. The response MIME type is application/json. No OpenAPI schema or detailed documentation was found beyond the landing page; the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no additional content.\n\nBecause no response schema or example output is documented, the exact shape of the stock data returned is unknown. The endpoint path suggests it returns data for the WMT ticker specifically, but whether it provides real-time quotes, historical data, or summary financials cannot be confirmed from available materials.","tags":[],"capabilities":["stock-data","per-call-payment","x402-protocol","usdc-settlement","base-network","no-api-key","pay-per-use"],"categories":["finance","data"],"synonyms":["stock quote API","WMT stock data","Walmart stock price","x402 stock endpoint","crypto-paid stock API","USDC stock data","pay-per-call finance API"],"warnings":["No OpenAPI or response schema available — the shape of the stock data response is unknown","Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no useful content","It is unclear whether this returns real-time quotes, delayed data, or something else","The broader platform lists many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/WMT","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/WMT","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base).
