What can you build with Cloud Natural Language API?

Cloud Natural Language API is a Analytics API. Developers commonly use analytics APIs for:

tracking product usage and user behaviour
building custom reporting and BI dashboards
measuring marketing and campaign performance
running funnel, retention, and cohort analysis
aggregating metrics from multiple data sources

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. Cloud Natural Language API is free to use, making it a low-risk choice to experiment with.
