It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all gated behind per-request micropayments settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/stocks/MSFT/history` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (contract 0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys or rate limits are advertised; access is granted instantly upon payment. The payment timeout is 300 seconds.\n\nDocumentation is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical stock data includes (e.g., OHLCV, date ranges, granularity). The endpoint is confirmed live via a valid 402 challenge, but the actual data format and query parameters are unknown.","tags":[],"capabilities":["stock-history","financial-data","x402-payment","usdc-micropayment","base-network","per-request-billing","no-api-key"],"categories":["finance","data"],"synonyms":["MSFT stock history","Microsoft historical prices","stock price API","equity data endpoint","x402 stock data","micropayment stock API"],"warnings":["No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content","No OpenAPI or JSON schema describing request parameters or response format","Request body structure and supported query parameters are unknown","Response data fields (OHLCV, date range, granularity) are undocumented","Only the MSFT ticker path is documented in this listing; unclear if other tickers are supported at similar paths"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/MSFT/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/MSFT/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 x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base).
