To connect the APIs and get started playing around, you need to connect the following credentials to the corresponding nodes:

1. **OpenWeather Map** – [https://openweathermap.org/api](https://openweathermap.org/api)  
   ↳ Make sure to grab your API key and set it in the OpenWeather node.

2. **Perplexity** – [https://www.perplexity.ai/](https://www.perplexity.ai/)  
   ↳ Generate your API key and configure it under HTTP Request or a custom node.

3. **Tavily** – [https://tavily.com/](https://tavily.com/)  
   ↳ Sign up, retrieve your API key, and link it to the Tavily Search node or HTTP Request node.

Once all three are connected, you’re ready to start building and experimenting with workflows!
