Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or accounts are required — callers attach an X-PAYMENT header containing a valid x402 payment proof and receive JSON data in response.\n\nThe endpoint is part of a broader platform offering dozens of pay-per-call APIs across categories including data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific /api/v1/stocks/QCOM route serves stock information for the QCOM ticker, though the exact response schema (fields, depth of data, real-time vs. delayed) is not documented in the available materials.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no example request/response payloads, and no description of what fields the stock endpoint returns. The x402 challenge is live and well-formed, confirming the endpoint is operational, but consumers should be prepared to experiment to understand the response format.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stock-quote","per-call-pricing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price API","QCOM stock data","Qualcomm quote","equity market data","pay-per-call stock API","x402 stock endpoint","crypto-paid finance API"],"warnings":["No OpenAPI or schema documentation available — response format for /api/v1/stocks/QCOM is unknown","All documentation pages (/docs, /pricing, /README, /api) render only 'Connect wallet' with no content","Exact data returned (real-time vs delayed, fields included) is unverified","The broader platform lists many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/QCOM","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/QCOM","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 USDC on Base), but there is zero documentation: no OpenAPI spec, no example responses, no description of what stock data fields are returned.
