Pay-per-call stock quote for CSCO (Cisco) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com returns stock data for Cisco Systems (ticker: CSCO) as a JSON response, gated behind the x402 payment protocol. Each call costs $0.02 in USDC on the Base network — the on-chain challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys or accounts are needed; callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. This specific endpoint sits in the finance category and serves stock price data for CSCO. The HTTP method is POST. The response MIME type is application/json, but the exact response schema is not documented — no OpenAPI spec, examples, or detailed field descriptions were found in the crawl.
Because documentation is extremely thin (the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content), the actual fields returned in the stock data response are unknown. Callers should expect typical stock-quote fields (price, volume, change, etc.) but this is inference, not confirmed. The endpoint is live and returning a well-formed x402 challenge.
