It is part of a broader platform offering dozens of pay-per-call APIs spanning finance, AI/ML, data analytics, and infrastructure utilities — all settled on the Base network using USDC.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-request.\n\nThe platform lists a uniform $0.02/request price across all its endpoints. Documentation beyond the landing page is sparse; the /docs, /pricing, and /README pages all resolve to a minimal \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec or detailed schema describing the response format for stock price queries. The specific fields returned (e.g., current price, volume, timestamp) must be discovered by making a paid request.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-settlement","base-network","per-request-micropayment","json-response"],"categories":["finance","data"],"synonyms":["stock price API","ABT stock price","equity price feed","real-time stock data","micropayment stock API","x402 finance API","pay-per-call stock price"],"warnings":["No OpenAPI or response schema available — response fields must be discovered empirically","Documentation pages (/docs, /pricing, /README) are all empty beyond a wallet-connect prompt","No information on data source, update frequency, or coverage of stock tickers beyond ABT","Platform appears to be a generic multi-purpose API hub; quality and reliability of individual endpoints is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/ABT/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/ABT/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base).
