Real-time AAPL stock price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current stock price for AAPL (Apple Inc.) via a pay-per-call x402 protocol. It is hosted on lowpaymentfee.com, a platform offering a broad catalog of data, AI, finance, and utility APIs — all priced at $0.02 per request and settled in USDC on the Base network. No API keys, accounts, or rate limits are required; callers simply attach an x402 payment header to each POST request.
The specific endpoint at `/api/v1/stocks/AAPL/price` is part of the Finance & Web3 category on the platform. The x402 challenge confirms the endpoint is live, accepting payments of up to 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. The payment timeout is 300 seconds. The response MIME type is `application/json`.
Note that the crawled documentation pages (docs, pricing, API, README) all returned only a "Connect wallet" prompt with no substantive content, so the exact response schema for this stock price endpoint is unknown. The platform's landing page lists many endpoints but provides no detailed field-level documentation for any of them. Treat the response format as undocumented.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented response format, and all documentation pages returned only a wallet-connect stub. The actual data quality and response structure must be inferred.
Warnings
- —No response schema documented — the exact JSON fields returned are unknown.
- —All documentation pages (/docs, /pricing, /api, /README) returned only 'Connect wallet' with no content.
- —The endpoint path is ticker-specific (/stocks/AAPL/price); it is unclear whether other tickers are supported or how to discover them.
