It is part of a broader suite of finance, analytics, AI, and utility APIs all priced at $0.02 per request, settled via x402 using USDC on the Base network. No API keys or accounts are required — callers simply attach an x402 payment header to a POST request.\n\nThe x402 challenge confirms the endpoint is live and accepts USDC (contract 0x8335…2913 on Base) with a maxAmountRequired of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The response MIME type is application/json.\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the quote response contains. The endpoint path suggests it returns a financial quote for the GS ticker, but the exact response schema is unknown.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-settlement","base-network","per-request-pricing","no-api-key"],"categories":["finance","market-data"],"synonyms":["Goldman Sachs quote","GS stock price","equity quote API","stock market data","financial quote","ticker quote","x402 finance API"],"warnings":["No OpenAPI or JSON schema available for request or response payloads","Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no usable content","Exact fields returned in the market quote response are unknown","Data source and freshness of the GS quote are undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/GS","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/GS","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, and all documentation pages render only a wallet-connect prompt.
