Each request costs $0.02, paid in USDC on the Base network. The endpoint accepts POST requests and returns JSON. No API keys or accounts are required — callers simply attach an x402 payment header with each request.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. This specific endpoint falls under the finance category and serves stock-level data for the ACN ticker. The x402 challenge confirms the endpoint is live, using the \"exact\" payment scheme with USDC (contract 0x8335…2913) on Base.\n\nDocumentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The actual fields returned by the stock data endpoint are unknown — callers should expect a JSON object with stock-related information for ACN but will need to experiment to discover the exact shape.","tags":[],"capabilities":["stock-data","per-call-payment","x402-protocol","usdc-settlement","base-network","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price API","ACN stock data","Accenture stock API","pay-per-call stock endpoint","x402 stock data","USDC stock API","Base network finance API"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all return only a wallet-connect prompt with no content","No OpenAPI or schema definition; request body format and response fields are unknown","The specific stock data provided (real-time quotes, historical, fundamentals, etc.) is unspecified","Cannot verify data source or accuracy of stock information returned"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/ACN","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/ACN","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 confirms pricing and payment details, but there is zero documentation, no OpenAPI spec, no request/response schema, and no examples.
