Pay-per-call stock price lookup for GE via x402 on Base (USDC).
What it does
This x402 endpoint at lowpaymentfee.com returns the current stock price for General Electric (GE) in response to a POST request. It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning finance, AI/ML, data analytics, and utility categories. Payment is settled on the Base network using USDC (contract 0x8335…2913) at $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an x402 payment header to each request.
The endpoint was confirmed live via a 402 challenge response. The x402 challenge specifies scheme "exact", meaning the caller pays a fixed amount per call. The output MIME type is application/json. Beyond this specific /stocks/GE/price path, the provider advertises similar endpoints for other financial data (price feeds, exchange rates, crypto quotes, gas estimates) as well as AI inference and utility services, all at the same $0.02 price point.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The actual data source for stock prices is unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI spec, no documentation, no example request/response payloads, and no information about the data source or response schema. The docs pages are all blank beyond a wallet-connect prompt.
