n8n Astrology Chat Agent: Google Gemini + RoxyAPI Natal Chart

Get a live natal chart, daily horoscope, and tarot card—inside an n8n hosted chat

This n8n Astrology Chat Agent uses Google Gemini and RoxyAPI to help users generate a birth-location-aware natal chart, receive a daily horoscope, and draw a daily tarot card—all through a public hosted chat experience.

What this workflow does

• Hosts a public chat in n8n: The workflow receives messages via an n8n hosted chat trigger and routes them to an astrology-focused AI agent.
• Maintains chat context: It uses 10-message conversation memory so the agent can follow along during the session.
• Resolves birth city and timezone with RoxyAPI: When a user provides a birth city, the workflow calls RoxyAPI to search matching cities and retrieve latitude, longitude, and the IANA timezone.
• Generates a natal chart: With birth date/time plus the resolved location, it generates a natal chart using RoxyAPI.
• Fetches a daily horoscope: It retrieves daily horoscope content for a requested zodiac sign—or, if none is provided, it can use the user’s Sun sign derived from the natal chart.
• Draws a daily tarot card: It generates a daily tarot card via RoxyAPI, using the user’s first name as a seed, and returns a short reading grounded in the tool results.

Use cases

• Launch a chat-based astrology assistant for your website or SaaS without building custom astrology tooling.
• Create an automation workflow that turns user-provided birth details into consistent daily insights (horoscope + tarot).
• Use Gemini + RoxyAPI to prototype an AI-driven personalization experience in n8n.
