What it does

This endpoint provides historical stock data for S&P Global (ticker: SPGI) 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 inference, finance, crypto, and utility services. All endpoints on the platform use the same pricing model: $0.02 per request, settled in USDC on the Base network.

The specific endpoint at `/api/v1/stocks/SPGI/history` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol — callers include an `X-PAYMENT` header with a signed payment proof for up to 20,000 base units of USDC (i.e., $0.02). No API keys, accounts, or rate limits are advertised; access is gated solely by the micropayment. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base.

Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render 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 or what query parameters are accepted. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data format and coverage are unknown.
