Potential JSON formatting issues in some cURL example

[schwentker]

I noticed what might be some JSON formatting issues in a few of the cURL examples that could cause problems for developers trying to use them.

Examples that might need review:

1. Create agents example - The JSON structure appears to have some formatting issues:
   {
   type:
   type: string
   description: The type of agent used to handle queries.

2. Bulk delete external users example - The JSON formatting seems inconsistent:
   {
   "external_users":
   "type": "array"
   "description": "List of external users to delete."

3. Create whitelist entry example - Contains what might be a typo:
   "direction": "inboud"
   (Should this be "inbound"?)

Impact:
These formatting issues might prevent devs from successfully copying & using the examples directly.

Suggestion:
Could these examples be reviewed for JSON syntax? I tested them with a JSON validator & they showed parsing errors, though I might be missing some context about the intended format.
