Get the current stock price for JNJ (Johnson & Johnson) via x402 micropayment on Base.
What it does
This endpoint returns the current stock price for Johnson & Johnson (ticker: JNJ) as a pay-per-call API secured by the x402 protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20000 base units, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are required; access is granted instantly upon payment. The endpoint accepts POST requests and returns JSON.
The provider's landing page lists many other endpoints across categories like sentiment analysis, text summarization, exchange rates, gas estimates, and geocoding — all at the same $0.02 price point. Documentation pages beyond the landing page were largely empty (showing only a "Connect wallet" prompt), so details about request/response schemas, supported parameters, and error handling are not available from the crawl.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The actual response payload for a successful call is unknown.
