Get the current MSFT stock price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current stock price for Microsoft (MSFT) via a pay-per-call x402 protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of data, AI, finance, and utility APIs all priced at $0.02 per request, settled in USDC on the Base network. No API keys or accounts are required — callers simply attach an x402 payment header to each POST request.
The x402 challenge confirms the endpoint is live and accepts the "exact" payment scheme on Base, requiring up to 20,000 base units of USDC (0x8335…2913), which equals $0.02 given USDC's 6 decimals. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a maximum timeout of 300 seconds. The response MIME type is application/json.
The provider's landing page lists many other endpoints across categories like analytics, AI/ML (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and infrastructure (geocoding, validation, conversion, generation), all at the same $0.02 price point. Documentation pages beyond the landing page returned only a "Connect wallet" prompt with no further technical detail, so the exact response schema for this stock price endpoint is not documented.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and all docs pages beyond the landing page are empty ('Connect wallet' only). The actual response payload structure must be inferred.
Warnings
- —No documentation available — docs, API, pricing, and README pages all return only 'Connect wallet' with no technical content.
- —Response schema for the stock price endpoint is unknown; no example responses are provided.
- —It is unclear whether this endpoint returns real-time, delayed, or simulated stock data.
- —The provider hosts many diverse endpoints (AI, finance, utilities) all at the same price, which may indicate a demo or early-stage platform.
