Why people use Polygon.io
Polygon.io Stock Market Data for Faster Financial Research
This Connector changes that by bringing the data to you. Instead of you going to the data, the data comes to your chat. You can ask for a company's entire dividend history or a specific day's aggregate bars, and your agent just hands it over. You get to spend your time on the analysis instead of the data entry.
What Vinkius changes
You get live financial data inside your chat window without the manual copy-pasting.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.
