Pay-per-call stock quote for JNJ (Johnson & Johnson) via x402 on Base, settled in USDC.
What it does
This endpoint provides stock data for Johnson & Johnson (ticker: JNJ) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI/ML, and utilities, all accessible via the x402 payment protocol on the Base network using USDC.
The endpoint is live and returns a 402 challenge requesting a per-call payment of $0.02 (20,000 base units of USDC with 6 decimals) settled to a Base address. No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The response MIME type is application/json, and the HTTP method is POST.
Documentation beyond the landing page is essentially empty (all sub-pages just show "Connect wallet"), so the exact response schema for the JNJ stock endpoint is unknown. It is reasonable to infer it returns price or quote data for JNJ, but the specific fields, data sources, update frequency, and coverage (real-time vs. delayed) are not documented. Prospective users should test with a single paid call to inspect the response before building integrations.
