Pay-per-call stock data endpoint for ticker SO, settled in USDC on Base via x402.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides stock data for the ticker symbol SO (Southern Company) via a simple POST request. Payment is handled inline using the x402 protocol: each call costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services — all at a flat $0.02 per request. The specific endpoint `/api/v1/stocks/SO` appears to be a stock-specific route, likely returning price or quote data for the SO ticker. However, no detailed documentation, request/response schema, or example payloads are available from the crawled material; the docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.
Because the endpoint returned a well-formed 402 challenge with x402 version 1, it is confirmed live. The payment is settled to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maximum amount required is 20,000 base units, which at 6 decimals equals $0.02 — consistent with the site's advertised flat pricing. No OpenAPI spec, AI plugin manifest, or agents.txt was found.
