Pay-per-call stock quote for HD (Home Depot) via x402 on Base, settled in USDC.
What it does
This endpoint provides stock data for the ticker HD (Home Depot) through the lowpaymentfee.com platform, an x402-enabled API marketplace. The endpoint is live and returns an x402 payment challenge requiring 20,000 base units of USDC on the Base network, which equals $0.02 per request (USDC uses 6 decimals). Payment is handled via the x402 "exact" scheme — no API keys, subscriptions, or rate limits are needed; each call is paid individually with an on-chain USDC microtransaction.
The provider hosts a broad catalog 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 endpoint probed here (/api/v1/stocks/HD) is not explicitly listed on the landing page's catalog, but it follows the same URL pattern and returns a valid x402 challenge with the same pricing. No OpenAPI schema, response examples, or detailed documentation were found during the crawl — the docs, pricing, and README pages all rendered only a "Connect wallet" prompt with no additional content.
Because no response schema or sample output is available, the exact shape of the stock data returned after payment is unknown. Callers should expect a JSON response (the challenge declares mimeType "application/json") but should be prepared for an undocumented structure. The endpoint accepts POST requests.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no response examples, no documentation beyond a wallet-connect prompt, and the specific /stocks/HD path is not listed in the provider's own catalog. Effectively a stub with confirmed liveness.
