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 APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint at `/api/v1/stocks/CB/price` is a POST endpoint that returns JSON. Documentation beyond the landing page is sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no additional technical detail.\n\nBecause there is no OpenAPI schema, no example responses, and no documentation describing the response format, callers should expect a JSON object containing price information for the CB stock ticker but will need to discover the exact shape empirically.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["Coinbase stock price","CB ticker price","stock quote API","equity price endpoint","real-time stock data","x402 stock API"],"warnings":["No OpenAPI or JSON schema available for request or response bodies","Documentation pages (/docs, /pricing, /api, /README) all render only a 'Connect wallet' prompt with no technical content","Response format for the stock price endpoint is unknown — no examples provided","The broader lowpaymentfee.com platform lists many endpoints but none have detailed documentation"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/CB/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/CB/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) with clear pricing ($0.02 USDC on Base), but there is no OpenAPI schema, no example request/response, and the docs pages are empty stubs.
