Pay-per-call stock quote for QCOM via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com returns stock data for Qualcomm (QCOM) via an x402-gated HTTP POST call. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or accounts are required — callers attach an X-PAYMENT header containing a valid x402 payment proof and receive JSON data in response.
The endpoint is part of a broader platform offering dozens of pay-per-call APIs across categories including 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/QCOM route serves stock information for the QCOM ticker, though the exact response schema (fields, depth of data, real-time vs. delayed) is not documented in the available materials.
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 spec, no example request/response payloads, and no description of what fields the stock endpoint returns. The x402 challenge is live and well-formed, confirming the endpoint is operational, but consumers should be prepared to experiment to understand the response format.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation: no OpenAPI spec, no example responses, no description of what stock data fields are returned. The docs/pricing/README pages are all empty wallet-connect stubs. This is effectively a stub listing.
