Pay-per-call stock quote API for VZ (Verizon) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker VZ (Verizon Communications) through an x402-gated API. Each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required — you simply attach an x402 payment header to a POST request and receive a JSON response.
The provider operates a broader platform offering dozens of pay-per-call endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. The specific /api/v1/stocks/VZ endpoint is not explicitly listed on the homepage catalog (which focuses on analytics, AI, finance, and utility categories), but the x402 challenge is live and returns a valid 402 response with payment terms.
Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of the stock data fields returned. The endpoint is confirmed live via the 402 challenge, but the actual response format after payment is unknown.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or what stock data fields are returned. The /stocks/VZ path is not listed on the provider's own homepage catalog, and all doc pages are empty. This is effectively a stub listing.
