Automate stock research and insights with financial APIs

This intelligent automation system leverages cutting-edge financial APIs from Danelfin, TwelveData, and Alpha Vantage to perform automated stock market analysis and generate predictive insights within a centralized workflow.

The system is triggered by chat messages received via popular messaging platforms like Slack, Telegram, WhatsApp, or Gmail, and it then fetches price history, technical indicators, and news data to provide comprehensive stock research reports. The analysis is powered by AI models from OpenAI and Cohere, delivering professional-grade investment insights to users for informed decision-making.

How Latenode estimates time and cost

Latenode bills workflow runs in credits: 1 credit = 30 seconds of processing. Minimum charge per run depends on your plan. 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.
