Get the current stock price for NOC (Northrop Grumman) via x402 micropayment on Base.
What it does
This endpoint returns the current stock price for Northrop Grumman (ticker: NOC) as a pay-per-request API using the x402 protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com, which covers data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge confirms the endpoint is live, accepting POST requests with an exact payment scheme. The maximum amount required is 20,000 base units of USDC (6 decimals), which equals $0.02 per call. No API keys or rate limits are advertised; access is gated solely by the x402 payment header.
The endpoint path follows the pattern `/api/v1/stocks/{ticker}/price`, suggesting it may support other stock tickers beyond NOC, though only the NOC path was probed. Documentation on the site is minimal — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. No OpenAPI schema or response examples are provided by the site.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented response format, no example responses, and the site's docs/pricing/README pages are all empty beyond a wallet-connect prompt. The actual data source for stock prices is unknown.
Warnings
- —No response schema or example response is documented; the shape of the returned stock price data is unknown.
- —Documentation pages (/docs, /pricing, /README, /api) contain no useful content — only a 'Connect wallet' prompt.
- —The data source for stock prices is not disclosed; accuracy and freshness cannot be verified.
- —Only the NOC ticker path was probed; support for other tickers is inferred from the URL pattern but unconfirmed.
