It is part of a broader suite of Finance & Web3 APIs offered by the provider, which includes price feeds, exchange rates, token quotes, and gas estimates, all accessible via the x402 payment protocol on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach a USDC payment on Base in the X-PAYMENT header. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. There are no API keys, no rate limits, and no subscription commitments — each request is independently paid for at the time of the call.\n\nThe provider's landing page lists numerous API categories (data & analytics, AI/ML, finance, infrastructure) all at the same $0.02/request price point. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show \"Connect wallet\"), so the exact request parameters and response schema for this specific quote endpoint are unknown. The endpoint is confirmed live via a valid 402 challenge, but the lack of documentation means callers will need to experiment or contact the provider to understand the expected POST body and response format.","tags":[],"capabilities":["stock-market-quote","x402-payment","usdc-micropayment","base-network","json-api","per-request-pricing"],"categories":["finance","market-data"],"synonyms":["stock quote API","ADI quote","Analog Devices stock price","market data API","equity quote endpoint","x402 finance API","micropayment stock data"],"warnings":["No documentation available — all doc pages return only 'Connect wallet' with no content","Request body schema and response schema are completely unknown","The specific data returned for a market quote (price, volume, timestamp, etc.) is not documented","Provider offers many endpoint categories but none appear documented beyond the landing page listing"],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/ADI","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/market/quote/ADI","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 USDC on Base).
