Each call costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — payment is handled inline via the X-PAYMENT header.\n\nThe endpoint is live and returns a 402 challenge with an x402 Version 1 payload specifying the exact payment scheme. The response MIME type is application/json. The provider site lists a broad catalog of endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services, all at the same $0.02 per request price point. However, documentation beyond the landing page is essentially empty (all sub-pages just show \"Connect wallet\"), so there is no detailed schema for request parameters or response fields for this specific stock-price endpoint.\n\nBecause the endpoint URL embeds the ticker symbol (WM) in the path, it likely returns price data specifically for Walmart stock. The exact response schema (fields, units, timestamps) is not documented and must be discovered by making a paid request.","tags":[],"capabilities":["stock-price","real-time-data","x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key"],"categories":["finance","data"],"synonyms":["stock quote","equity price","WM stock","Walmart stock price","market data","stock ticker API","x402 finance API"],"warnings":["No documentation available — all sub-pages (docs, api, pricing, README) render only 'Connect wallet'","Response schema for the stock price endpoint is completely undocumented","No OpenAPI spec or AI plugin manifest found","Unclear whether the endpoint returns real-time, delayed, or end-of-day pricing"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/WM/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/WM/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 per request in USDC on Base).
