Pay-per-call stock quote for CVS via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for CVS (CVS Health Corporation) through an x402-gated API call. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific /api/v1/stocks/CVS endpoint is not listed on the provider's landing page among the showcased APIs, but the x402 challenge is live and returns a well-formed 402 response. Documentation is extremely thin — the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content.
Because there is no OpenAPI schema, no example request/response payloads, and no documentation describing the response format, the exact fields returned are unknown. Callers should expect a JSON object with stock price or quote data for CVS, but the structure must be discovered empirically.

Quality

The response format is entirely unknown.
