It uses the x402 payment protocol, settling in USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per request. The stock price endpoint specifically lives under the finance category and is accessed via HTTP POST. The response MIME type is application/json.\n\nDocumentation on the site is minimal — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema beyond the MIME type. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the exact shape of the returned stock price data is unknown.","tags":[],"capabilities":["stock-price","real-time-data","x402-payment","usdc-settlement","base-network","no-api-key","pay-per-request"],"categories":["finance","data"],"synonyms":["stock quote","equity price","NKE price","Nike stock","stock market data","real-time stock price","ticker price API"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","Docs, pricing, and API pages on the site render only 'Connect wallet' with no technical content","No example request or response payloads could be found","The specific data source for stock prices is not disclosed — accuracy and freshness are unverifiable"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/NKE/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/NKE/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base).
