It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, crypto, and utility services. The endpoint accepts POST requests and returns JSON.\n\nPricing is $0.02 per request, paid in USDC on the Base network (the x402 challenge advertises a maxAmountRequired of 20000 base units, which equals $0.02 given USDC's 6 decimals). There are no API keys, no rate limits, and no subscription commitments — payment is handled entirely through the x402 protocol's X-PAYMENT header. The provider's landing page confirms a flat $0.02/request model across all endpoints.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of the expected POST body or response format. The endpoint is confirmed live (402 challenge returned), but the lack of documentation means callers will need to experiment or contact the provider to determine the correct request payload and interpret the response structure.","tags":[],"capabilities":["stock-history","financial-data","per-request-payment","x402-protocol","usdc-base-network","json-api"],"categories":["finance","data"],"synonyms":["stock price history","ADI stock data","Analog Devices historical prices","equity market data","stock ticker history","x402 stock API"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or input/output schema provided; request body format and response structure are unknown.","Endpoint is specific to ticker ADI; unclear if other tickers are available at similar paths.","Provider offers a very broad set of APIs (AI, finance, utilities) at a uniform price, which may indicate placeholder or thin-wrapper services."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/ADI/history","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/ADI/history","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/request in USDC on Base).
