Pay-per-call stock market quote for IBM via x402 on Base (USDC), $0.02/request.
What it does
This x402 endpoint at lowpaymentfee.com provides a market quote for the ticker IBM. It is part of a broader platform offering data & analytics, AI/ML, finance, and infrastructure APIs, all priced at $0.02 per request and settled in USDC on the Base network. No API keys or rate limits are required — callers simply attach an x402 payment header with each request.
The specific endpoint `/api/v1/market/quote/IBM` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, requesting a maximum of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for market quotes. The endpoint path suggests it returns a price quote for IBM stock, but the exact fields returned are unknown.
