Stock market quote for JNJ via x402 micropayment on Base, $0.02 per request in USDC.
What it does
This endpoint provides a stock market quote for the ticker JNJ (Johnson & Johnson) through the lowpaymentfee.com platform. It is part of a broader suite of finance, analytics, AI, and utility APIs all accessible via the x402 payment protocol on the Base network. Each request costs $0.02 in USDC (20,000 base units of USDC with 6 decimals = $0.02), settled on-chain with no API keys, no rate limits, and no upfront commitments.
The endpoint accepts HTTP POST requests and returns JSON. The x402 challenge is live and correctly returns a 402 Payment Required response advertising the payment terms. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maximum timeout for payment settlement is 300 seconds.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of the response format for the quote endpoint. The specific fields returned in a JNJ quote (e.g., price, volume, change) are unknown from the available material.
