To visualize Ethereum's story through data. Making data on the Ethereum ecosystem easily accessible to all ecosystem participants and help tell the story.

## Key Facts

* growthepie exposes public JSON at `https://api.growthepie.com/`
* growthepie tracks chains, projects, metrics, and data availability metadata
* `master.json` is the canonical metadata entry point
* Flat exports use `metric_key`, `origin_key`, `date`, and `value`
* Data is only available for chains that work with growthepie
* Chain-level data belongs to the Basic package and application-level data belongs to the Advanced package. More info: [growthepie data tiers](https://www.growthepie.com/sales#data-tiers)
