The Blnk CLI does not use a global --format flag. Output depends on the command you run and the flags you pass.

​
Output modes

The CLI picks a format from the command you run; there is no global --format switch. Use this table to know what to expect before you pipe output elsewhere.

​
Table output

Resource list commands (without --id) render an ASCII table with column headers, then a footer with total results and page number. Tables are meant for scanning many records in the terminal, not for machine parsing.

List resources

Run any resource list command without --id:
blnk ledgers list

Summary output

After create or when you run list --id without --json, the CLI prints a short labeled block with the fields most people need day to day. This is the default human-readable detail view; switch to JSON when you need every API field.
200 Success
Ledger details:

JSON output

Pass --json on supported commands to print the raw Core API response as pretty-printed JSON. Ideal for scripts, jq, or comparing CLI behavior to your HTTP integration. 
blnk ledgers list --id ldg_46074f0e-898d-4b48-bced-d647816168c0 --json
200 Success
