Top Free Crypto APIs for Notion

In this guide, I’m sharing a curated list of the most-used crypto APIs by Note API Connector users. These APIs let you import live crypto data like prices, market caps, or volume directly into your Notion workspace, without writing a single line of code.

Many of them offer free access to public market data, and I’ve noted which require authentication and which can be used instantly without an API key. Where possible, you’ll also find sample endpoints so you can explore the data in your browser or connect it straight into Notion.

This list focuses on public crypto data, ideal for building dashboards, tracking your favorite coins, or analyzing trends. For private account-level data like portfolio balances or transaction history, authentication is always required.
