It is part of a broader platform offering data & analytics, AI/ML inference, finance, crypto, and utility APIs — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. Payment is settled on the Base network using USDC (contract 0x8335…2913).\n\nThe specific endpoint `/api/v1/stocks/FDX` accepts HTTP POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a max amount of 20,000 base units of USDC (6 decimals), which equals $0.02 per call. The platform advertises itself as keyless and instant-access: callers attach an `X-PAYMENT` header containing a valid x402 payment proof and receive the response directly.\n\nDocumentation is extremely thin — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the stock data response contains. The endpoint is confirmed live via the 402 challenge, but the actual response shape must be discovered by making a paid call.","tags":[],"capabilities":["stock-quote","per-call-payment","x402","usdc-settlement","base-network","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["FedEx stock price","FDX stock data","stock market API","equity quote API","pay-per-call stock API","x402 stock endpoint"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or output schema provided; response format for stock data is entirely unknown.","The specific endpoint is /api/v1/stocks/FDX but the landing page does not list any /stocks/ endpoints, only finance/prices and finance/rates — this endpoint may be undocumented or experimental.","No example responses available; callers must discover the schema by making a paid request."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/FDX","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/FDX","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 challenge and pricing is clear ($0.02/call in USDC on Base).
