It is part of a broader suite of pay-per-request APIs hosted at lowpaymentfee.com, covering finance, analytics, AI/ML, crypto, and utility services. Payment is settled on the Base network using USDC (USD Coin) at $0.02 per call — no API keys, no rate limits, and no subscriptions required.\n\nThe endpoint accepts POST requests and returns application/json. The x402 payment challenge was successfully captured, confirming the endpoint is live. The payment is made via the \"exact\" scheme to a specified wallet address, with a maximum timeout of 300 seconds. The asset used is USDC on Base (contract 0x8335…2913).\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific input parameters (if any beyond the ticker symbol in the URL path) and the exact response shape are unknown and must be inferred from the endpoint path pattern.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-settlement","base-network","per-request-pricing","no-api-key","real-time-data"],"categories":["finance","data"],"synonyms":["CSCO stock price","Cisco share price API","stock quote API","equity price endpoint","x402 stock data","micropayment stock API","pay-per-call stock price"],"warnings":["No OpenAPI spec or schema documentation available","All documentation pages (/docs, /api, /pricing, /README) return only 'Connect wallet' with no content","Response format and fields are unknown — no example responses documented","Input parameters beyond the URL path ticker symbol are undocumented","The broader platform lists many endpoints but none have detailed docs"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/CSCO/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/CSCO/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
