Historical stock data for PM (Philip Morris) via x402 micropayment on Base, $0.02/request.
What it does
This endpoint provides historical stock price data for the ticker PM (Philip Morris International) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI/ML, and utilities, all settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header using the x402 exact-payment scheme. The maximum amount required per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 USD (USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each request is independently paid.
Documentation beyond the landing page is sparse: the /docs, /pricing, and /api pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response schema, and no description of what fields the historical stock data response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request parameters (e.g., date range, interval) and response shape are unknown.
