Stock market quote for REGN via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides a stock market quote for the ticker symbol REGN (Regeneron Pharmaceuticals) through an x402-enabled pay-per-call API hosted at lowpaymentfee.com. The endpoint accepts POST requests and returns JSON data. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider, lowpaymentfee.com, operates a broad catalog of x402 endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced uniformly at $0.02 per call. The specific endpoint `/api/v1/market/quote/REGN` falls under the Finance & Web3 category and is designed to return a market quote for the REGN equity ticker. No API keys or rate limits are advertised; access is gated solely by the x402 payment header.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data source, response schema, and data freshness are unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no example request or response, and all documentation pages are empty beyond a wallet-connect prompt. The actual data source and response format are completely unknown, making this effectively a stub listing.
