Stock earnings data for AAPL via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides stock earnings data for AAPL (Apple Inc.) through the x402 payment protocol. It is part of a broader suite of finance, analytics, AI, and utility APIs offered by the same provider, all priced at $0.02 per request and settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). There are no API keys, no rate limits, and no signup required — access is purely pay-per-call. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using the USDC contract on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
Documentation is extremely sparse. The crawled docs, pricing, API, and README pages all returned only a "Connect wallet" prompt with no additional content. The specific request body schema and response format for the earnings endpoint are not documented anywhere in the available material. The endpoint is confirmed live (returns a proper 402 challenge), but without examples or schema details, callers will need to experiment or contact the provider to determine the expected input and output formats.
