It is part of the lowpaymentfee.com platform, which offers a variety of pay-per-call APIs spanning finance, AI/ML, data analytics, and infrastructure utilities — all settled on the Base network using USDC.\n\nThe endpoint accepts POST requests and returns JSON. Each call costs $0.02 (20,000 base units of USDC on Base, which uses 6 decimals). Payment is handled inline via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The x402 challenge was confirmed live, returning a 402 with a well-formed payment challenge advertising the USDC asset contract `0x8335…2913` on Base.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact request body format and the shape of the historical data response are unknown and must be discovered experimentally.","tags":[],"capabilities":["stock-history","historical-price-data","x402-payment","usdc-base","per-request-billing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["JNJ stock history","Johnson & Johnson historical prices","stock price API","equity historical data","x402 stock data","micropayment stock API"],"warnings":["No OpenAPI or schema documentation available — request body format and response structure are unknown","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no technical content","The specific stock ticker (JNJ) is hardcoded in the URL path; it is unclear whether other tickers are supported at similar paths","No information on data source, update frequency, or historical date range coverage"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/JNJ/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/JNJ/history","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live via a valid 402 x402 challenge with clear pricing ($0.02 USDC on Base).
