Get the current stock price for Boeing (BA) via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current stock price for Boeing (ticker: BA) as a JSON response, gated behind an x402 micropayment of $0.02 per request settled in USDC on the Base network. It is part of a broader suite of APIs offered by lowpaymentfee.com spanning finance, AI/ML, data analytics, and utility services—all priced at $0.02 per call with no API keys, no rate limits, and no commitments required.
The x402 challenge was successfully captured, confirming the endpoint is live. The payment scheme is "exact" with a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Callers must include an X-PAYMENT header conforming to x402 version 1. The endpoint accepts HTTP POST requests and returns application/json.
Documentation beyond the landing page is extremely sparse—the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The exact data source for stock prices and update frequency are unknown.
