Real-time stock price data for WMT (Walmart) via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the current stock price for Walmart (ticker: WMT) as a pay-per-call API secured by the x402 protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com that span data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request and settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header using the x402 "exact" scheme: the caller signs a USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the provider's address on Base. No API keys, subscriptions, or rate limits are advertised — access is gated purely by micropayment.
Documentation beyond the landing page is extremely thin. The /docs, /pricing, /api, and /README pages all resolve to a minimal "Connect wallet" prompt with no additional technical detail, example requests, or response schemas. The exact shape of the response (fields, data source, update frequency) is not documented and must be inferred from the endpoint path and the provider's "Finance & Web3 — Market data and financial calculations" category label.
