It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all payable per-request via the x402 protocol on the Base network using USDC.\n\nThe endpoint charges $0.02 per request (20,000 base units of USDC with 6 decimals) and requires no API keys, accounts, or rate-limit management. Callers send an X-PAYMENT header containing a signed x402 payment proof; the server validates it and returns the stock price data. The payment settles on-chain to the provider's address on Base using the \"exact\" scheme.\n\nDocumentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all resolve to a wallet-connect stub with no additional technical detail. There is no OpenAPI spec, no sample response schema, and no information about what fields the stock price response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format must be discovered by making a paid request.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-micropayment","base-network","per-request-billing","no-api-key"],"categories":["finance","data"],"synonyms":["stock price API","equity price lookup","ITW stock quote","Illinois Tool Works price","real-time stock data","x402 finance API","micropayment stock API"],"warnings":["No OpenAPI or response schema available — response format is undocumented","All documentation pages (/docs, /pricing, /README) return only a wallet-connect stub with no content","The specific stock ticker (ITW) is hardcoded in the URL; it is unclear whether other tickers are supported at similar paths","No sample response is available; the fields returned for a stock price query are unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/ITW/price","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/ITW/price","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 with a valid 402 challenge and clear pricing ($0.02 USDC on Base).
