Historical stock price data for CVS via x402 micropayment on Base network.
What it does
This endpoint provides historical stock price data for CVS Health Corporation (ticker: CVS) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-request APIs offered by the provider, spanning finance, AI, data analytics, and utility categories. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request.
The endpoint is live and returns a standard x402 402 challenge when called without payment. It accepts POST requests and returns JSON. The specific URL pattern (`/api/v1/stocks/CVS/history`) suggests the provider may offer similar endpoints for other stock tickers, though only CVS is confirmed here. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content.
Pricing is straightforward: $0.02 per request (20,000 base units of USDC, which has 6 decimals = $0.02). The provider advertises no API keys, no rate limits, and instant access. There is no information about the data source, historical date range coverage, response fields, or update frequency, so the actual quality and depth of the stock history data cannot be verified from available materials.
