Get the current stock price for Goldman Sachs (GS) via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current stock price for Goldman Sachs (ticker: GS) as a JSON response, paid per request using the x402 protocol. 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.
The 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.
The 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.
