Historical stock price data for JPM via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides historical stock price data for JPMorgan Chase (JPM) through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning data analytics, AI/ML, finance, crypto, and utility services. Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address on Base. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical stock data includes (e.g., OHLCV, date ranges, granularity). The endpoint path suggests it returns historical price data for JPM, but the exact input parameters and output format are unknown.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and no documentation beyond the landing page listing. The exact input parameters and output format are entirely unknown, making this effectively a stub listing.
