Messari Typescript SDK

For the best developer experience, it is recommended that TS / JS users use the official Messari Typescript SDK . See the detailed examples for reference.

API Key

For both the Typescript SDK and the REST APIs, you'll need a Messari API Key. See Authentication

🚧

Authorization

If you are receiving an Unauthorized error when calling an endpoint, it is likely that your API key is not provisioned to access that service. Contact [email protected] to inquire about access or if you believe you should have access they can quickly update your permissions.
