Pay-per-call stock price lookup for META via x402 on Base (USDC).
What it does
This endpoint returns the current stock price for META (Facebook/Meta Platforms) via a simple POST request, settled through the x402 payment protocol on the Base network using USDC. Each call costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — payment is handled inline via the X-PAYMENT header.
The endpoint is part of a broader suite of APIs offered at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services — all priced uniformly at $0.02 per request. The stock price endpoint specifically lives under the finance category and returns JSON. The x402 challenge confirms the endpoint is live, discoverable, and accepts POST requests.
Documentation beyond the landing page is extremely thin — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The actual data source for stock prices is not disclosed.

Quality
The x402 challenge confirms the endpoint is live and pricing is clear ($0.02/call in USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages beyond the landing page are empty. The actual data source and response format are unknown.
