What it does

This endpoint provides historical stock price data for Qualcomm (QCOM) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML, finance, and infrastructure endpoints, all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.

The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge specifies a maxAmountRequired of 20,000 base units, which at 6 decimals for USDC equals $0.02 — consistent with the site's advertised pricing. The payment timeout is 300 seconds.

Documentation on the site 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 request/response examples, and no description of what fields the historical stock data includes or what query parameters are accepted. The endpoint URL pattern suggests it returns historical price data for the ticker symbol embedded in the path (QCOM), but the exact schema and supported parameters are unknown.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no documentation, no OpenAPI schema, no request/response examples, and no description of supported parameters or response fields. The docs pages are empty. This is effectively a stub listing.
