This template starts when a webhook receives a stock ticker. JavaScript fetches price history, technicals, and news from Danelfin, TwelveData, and Alpha Vantage.
ChatGPT writes a research note from that data. Supabase stores the result. Put those market-data API keys in the JavaScript node. ChatGPT is a Latenode AI node. Connect Supabase.
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.
