Create Table

Create a new Dune table with the specified name and namespace.

The resulting table will be empty, and can be inserted into with the /insert endpoint.

• If a table already exists with the same name, the request will fail.
• Column names in the table can’t start with a special character or a digit.
• Each successful table creation consumes 100 credits.
• To delete a table, you can go to user settings (dune.com) -> data -> delete or use the /delete endpoint.

Schema

You need to define the schema of your data by providing schema array of columns in the request. Each column has three parameters:

name: the name of the field

type: the data type of the field

Dune supports ISO 8601 timestamp format

nullable: if the column is nullable (true/false, true by default)
