Top Free Crypto APIs for Google Sheets
As of April 2022, there a huge number of crypto APIs, and virtually all of them offer data for free through their public endpoints. But they are not all equal; some offer more comprehensive data or provide unique endpoints.
This article lists the top crypto APIs accessed by users of the API Connector extension for Sheets in order of popularity (#1 is the most popular), along with some information:
- the type of authentication they require,
- the data points they provide,
- whether or not they share rate limits among users (shared rate limits make them less suitable for Google Sheets, since all requests run through Google’s servers).
Please note that the list below refers to each API’s free and public endpoints. Non-public endpoints may also be available with different offerings and requirements.
