Pay-per-call earnings data for XOM (ExxonMobil) via x402 on Base, settled in USDC.
What it does
This endpoint at lowpaymentfee.com provides earnings data for the stock ticker XOM (ExxonMobil) through the x402 payment protocol. It is part of a broader suite of finance and data APIs offered by the same provider, all priced at $0.02 per request and settled in USDC on the Base network. No API keys or accounts are required — callers simply attach an x402 payment header to a POST request and receive a JSON response.
The x402 challenge confirms the endpoint is live and accepts exact-scheme payments of up to 20,000 base units of USDC (0x8335…on Base), which equals $0.02 given USDC's 6 decimals. The payment is directed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The response MIME type is application/json.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no sample request/response, and no description of the earnings data schema returned. The specific fields, coverage period, and data source for the XOM earnings endpoint are unknown from the available material.
