'Changed companies' - Access denied - Subsriber level limitation?

[smith-jordan-f]

I'm successfully using the api other than 'changed companies' (getting an access denied error). Are there any limitations on this due to subscriber level? I couldn't find any limitations in the documentation.

curl --request GET
--url 'https://backend.simfin.com/api/v3/companies/changed-companies?start=2025-09-1'
--header 'Authorization: api-key xxxxxxxxxxxxxxxxxxxxxx'
--header 'accept: application/json'

Response:
{
"timestamp": "2025-09-20T17:48:45.809857779",
"status": "401",
"error": "Access is denied",
"message": "Access is denied"
}
