Historical stock price data for ACN (Accenture) via per-request x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for the ticker ACN (Accenture) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs covering finance, analytics, AI/ML, crypto, and utility services. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request. No API keys, subscriptions, or rate limits are required — callers simply attach an x402 payment header to each POST request.
The specific endpoint at `/api/v1/stocks/ACN/history` returns JSON and is discoverable via the x402 challenge. The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02.
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 technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available from the crawl. The exact fields returned in the historical stock data response, supported query parameters (e.g., date ranges, intervals), and data source are unknown.
