To keep our data accessible and sustainable, we use a simple tiered attribution system depending on your plan. All we ask is for a simple link back to our site.

Ideally, attribution should be placed right next to the data it describes. This helps users understand the source of the information instantly and keeps things contextual.
If your design is tight, we're also happy with being listed on a "Credits" or "Data Sources" page. The goal is clarity and transparency, however you choose to implement it.
Copy and paste this snippet directly into your app. This text link is our preferred way to credit the data.
