It is part of a broader suite of pay-per-call APIs covering finance, AI/ML, data analytics, and utility services, all settled via the x402 protocol on the Base network using USDC.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. Each call costs $0.02 (20,000 base units of USDC with 6 decimals) and settles on-chain to the provider's wallet. The x402 challenge was confirmed live, returning a proper 402 with payment parameters.\n\nThe specific data fields returned in the quote response are not documented; the provider's docs pages, pricing page, and README all render only a \"Connect wallet\" prompt with no further detail. Because of this, the exact schema of the response (e.g., whether it includes bid/ask, volume, last price, etc.) cannot be confirmed from available material. The broader lowpaymentfee.com site lists similar finance endpoints for price feeds, exchange rates, token quotes, and gas estimates, all at the same $0.02 price point.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key"],"categories":["finance","market-data"],"synonyms":["CVS stock quote","CVS Health stock price","equity quote API","stock market data","x402 finance API","micropayment stock API","CVS ticker"],"warnings":["No response schema documented — the fields returned in the stock quote are unknown.","Docs, pricing, and README pages all render only 'Connect wallet' with no usable documentation.","No OpenAPI or machine-readable schema available.","It is unclear whether this returns real-time, delayed, or cached stock data."],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/CVS","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/market/quote/CVS","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base).
