Historical stock price data for Goldman Sachs (GS) via x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for Goldman Sachs (ticker: GS) through the lowpaymentfee.com platform. It is part of a broader suite of finance, analytics, AI, and utility APIs all accessible via the x402 payment protocol on the Base network. Each request costs $0.02 in USDC, paid per-call with no API keys, subscriptions, or rate limits required.
The endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, settling payments in USDC (contract 0x8335…2913) on Base. The platform advertises a uniform $0.02 per request pricing model across all its endpoints. Beyond this specific stocks/history endpoint, lowpaymentfee.com offers endpoints for analytics metrics, AI inference (sentiment, summarization, classification, embeddings), crypto quotes, gas estimates, exchange rates, geocoding, and more.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical stock data includes or what parameters the POST body accepts. The endpoint appears functional based on the 402 challenge, but without documentation it is difficult to know the exact request format or response structure.
