It is part of a broader suite of APIs hosted at lowpaymentfee.com that cover data analytics, AI/ML inference, finance, crypto, and utility services.\n\nThe endpoint accepts POST requests and charges $0.02 per call, settled in USDC on the Base network. No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The x402 challenge was captured live, confirming the endpoint is operational and returning a well-formed 402 response with version 1 of the protocol.\n\nThe provider advertises uniform $0.02 pricing across all endpoints, no rate limits, and no minimum commitments. However, documentation beyond the landing page is extremely thin — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for this stock-price endpoint. The actual data source for stock prices is not disclosed.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-settlement","base-network","per-call-pricing","no-api-key"],"categories":["finance","data"],"synonyms":["stock price API","GS stock price","Goldman Sachs price","equity price feed","real-time stock data","x402 finance API","pay-per-call stock API"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","Documentation pages (/docs, /pricing, /README) are effectively empty","Data source for stock prices is not disclosed; accuracy and freshness are unverifiable","Only the GS ticker is in this endpoint path; breadth of ticker coverage is unclear"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/GS/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/GS/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base).
