Real-time stock price data for ADI (Analog Devices) via x402 micropayment on Base.
What it does
This x402 endpoint at lowpaymentfee.com returns the current stock price for ADI (Analog Devices, Inc.) in exchange for a per-request USDC micropayment on the Base network. The endpoint accepts POST requests and responds with JSON. Payment is handled via the x402 protocol — no API keys, accounts, or rate limits are required. The caller simply includes an X-PAYMENT header with a valid payment proof.
The cost per request is $0.02 (20,000 base units of USDC, which has 6 decimals). The payment is settled on-chain to the provider's address on Base. The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced at $0.02 per call.
Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec or example request/response schema available, so the exact request body format and response shape for this stock-price endpoint must be inferred or discovered experimentally.
