# Which API Should I use? 

GWI offers three ways to work with our data, depending on your workflow.

* **Platform API** exposes structured variables and tables for BI and modeling.
* **Spark API** returns concise, narrative insights from natural-language or structured queries.
* **Spark MCP** (via Spark) brings those insights directly into AI assistants and agent workflows.

  The table below outlines purpose, interaction style, output format, typical users, setup effort, and best-fit scenarios for each option.

| **Feature** | **Platform API** | **Spark API** | **MCP (via Spark)** |
| :- | :- | :- | :- |
| **Purpose** | Extract structured data for custom analysis and dashboards | Retrieve summarized, ready-to-use insights via queries | Integrate GWI insights  directly into AI assistants and workflows |
| **Interaction mode** | Structured API requests (parameter-based) | Natural language prompt or structured request | Natural language, machine-readable query translation |
| **Insight format** | Raw variables and tables | Summarized insights (e.g. X%s of Gen Z prefers Y) | Textualized outputs designed for LLMs/Copilots |
| **Use case examples** | Feed GWI data into BI dashboards, tools, or models | Ask questions and get insights about your specific audience to help with content planning or persona building | Enable copilots to answer audience questions and use these results to shape AI model outputs - whether generating text, creating imager, or guiding the actions of agents and other MCPs |
| **End user** | Data analysts, data engineers | PMMs, researchers, content strategists | Product, AI, innovation teams using assistants or LLM tools |
| **Setup effort** | High (requires integration and data handling) | Low (requires some understanding of query structure) | Low (using natural language) |
| **Best for** | Bulk analysis, exploration, custom visualizations | Self-serve insight discovery without logging into the platform | Real-time, context aware audience intelligence inside other tools, agentic platforms and workflows. |
| **Common tools integrated with** | Tableau, PowerBI | Internal tools, campaign planning | Chatbots, copilots, AI agents, Claude |
