Pay-per-call stock quote API for GE via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for General Electric (GE) via a simple POST request, gated by the x402 payment protocol. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The payment is settled on-chain to a specified wallet address using the "exact" scheme with a maximum amount of 20,000 base units (0.02 USDC, since USDC uses 6 decimals).
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services — all at the same $0.02/request price point. The specific endpoint probed here (`/api/v1/stocks/GE`) appears to be a stock-specific route, likely returning quote or price data for the GE ticker symbol.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the MIME type `application/json`. The endpoint is confirmed live via a valid 402 challenge, but the actual data quality and response structure remain unknown without a paid request.
