Pay-per-call stock price lookup for ticker SO via x402 on Base (USDC).
What it does
This endpoint at lowpaymentfee.com returns stock price data for the ticker "SO" (Southern Company) via a simple POST request. It uses the x402 payment protocol on the Base network, accepting USDC payments at $0.02 per request. No API keys or accounts are required — callers attach an X-PAYMENT header with a valid x402 payment proof and receive a JSON response.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per call. The platform advertises no rate limits, no minimums, and instant access. Payment settles on the Base L2 network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with the "exact" payment scheme.
Documentation 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 example request/response payloads, and no description of the response schema. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the actual data source and response format are unknown.

Quality
The endpoint is confirmed live via a valid 402 x402 challenge, but there is zero documentation on request parameters, response schema, or data sources. No OpenAPI spec, no examples, and all doc pages render only a wallet-connect prompt. The listing is effectively a stub.
Warnings
- —No documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no technical content.
- —No OpenAPI or schema definition found; response format is completely unknown.
- —No example request or response payloads available; actual data quality and source are unverified.
- —The specific ticker 'SO' is hardcoded in the URL path; it is unclear whether other tickers are supported at similar paths.
