Historical stock data for JNJ via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides historical stock price data for Johnson & Johnson (JNJ) through the x402 payment protocol. It is part of the lowpaymentfee.com platform, which offers a variety of pay-per-call APIs spanning finance, AI/ML, data analytics, and infrastructure utilities — all settled on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Each call costs $0.02 (20,000 base units of USDC on Base, which uses 6 decimals). Payment is handled inline via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The x402 challenge was confirmed live, returning a 402 with a well-formed payment challenge advertising the USDC asset contract `0x8335…2913` on Base.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact request body format and the shape of the historical data response are unknown and must be discovered experimentally.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation of request parameters or response schema, and no example payloads. The docs pages are empty beyond a wallet-connect prompt. Listing is functional but essentially a stub in terms of developer guidance.
