Historical stock price data for MCD (McDonald's) via pay-per-request x402 on Base.
What it does
This endpoint provides historical stock price data for McDonald's (ticker: MCD) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all priced at $0.02 per request with no API keys, no rate limits, and no commitments.
The specific endpoint at `/api/v1/stocks/MCD/history` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical stock data includes or what parameters the POST body accepts. Consumers should expect to experiment with the endpoint to discover its input and output format.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request parameters, no response examples, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The listing is essentially a stub with confirmed liveness.
