Pay-per-call stock quote for CVX (Chevron) via x402 on Base, settled in USDC.
What it does
This endpoint provides stock data for CVX (Chevron Corporation) through a pay-per-request x402 protocol on the Base network. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all priced at $0.02 per request with no API keys, no rate limits, and no commitments.
The specific endpoint `/api/v1/stocks/CVX` accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment on Base (contract `0x8335…2913`). The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout window.
No OpenAPI schema or detailed documentation was found beyond the landing page. The docs, pricing, and API pages all resolve to a minimal "Connect wallet" prompt, so the exact response shape for stock data is unknown. The endpoint is confirmed live — it returns a proper 402 challenge. However, the lack of documented request/response schemas and the absence of any sample data mean integrators will need to experiment or contact the provider to understand the payload format.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request body format, no example response, and the docs/pricing/API pages are all empty stubs. The actual data returned is entirely unknown, making this effectively a stub listing.
