Historical stock price data for PG (Procter & Gamble) via x402 micropayment on Base.
What it does
This endpoint at lowpaymentfee.com provides historical stock price data for the ticker PG (Procter & Gamble). It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header using the x402 exact scheme. The maximum amount required per call is 20,000 base units of USDC (0.02 USD), consistent with the platform's flat $0.02/request pricing. No API keys or account registration are needed — access is granted immediately upon valid payment. The platform advertises no rate limits.
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 from the crawl. The exact request body format and response structure for stock history data must be inferred or discovered experimentally.
