What it does

This endpoint returns the current stock price for Coinbase (ticker: CB) through the lowpaymentfee.com platform. It uses the x402 payment protocol, settling in USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.

The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint at `/api/v1/stocks/CB/price` is a POST endpoint that returns JSON. 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.

Because there is no OpenAPI schema, no example responses, and no documentation describing the response format, callers should expect a JSON object containing price information for the CB stock ticker but will need to discover the exact shape empirically.
