Pay-per-call earnings data for Regeneron (REGN) via x402 on Base network.
What it does
This endpoint provides financial earnings data for Regeneron Pharmaceuticals (ticker: REGN) through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering various pay-per-request APIs across finance, AI, analytics, and infrastructure categories. Payment is settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live and charges 20,000 base units of USDC (which, at 6 decimals, equals $0.02 per request). The platform advertises no API keys, no rate limits, and instant access — you simply attach an x402 payment header to each call.
Note that documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show "Connect wallet"), so the exact request body schema and response format for this earnings endpoint are not documented. The endpoint is part of a broader finance category on the platform that also includes price feeds, exchange rates, token quotes, and gas estimates.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base), but there is no documented request schema, no response example, and all documentation pages are empty beyond the landing page. Effectively a stub listing.
