# List comparable deployments

`GET` `/comparables`

- `category` (string, required)
- `integration_count` (number, float, optional) - Reference size; matches are searched within a ±20 percent corridor.
- `period_months` (integer, optional)

        Every call carries an API key in the `apikey` header. You generate the
        key in the Nexora AI portal under "My Apps"; it's shown exactly once.

        Each key has the scopes it's allowed to use attached to it. If one is
        missing, the API responds with `403` and `code: "scope_missing"`; the
        missing scope is in `details[].field`.
