The provisioning of the key is identical for all users, enterprise or non.
However, based on usage, there are limits.
Taking Google maps as an example (from GCP)
Users of the standard API [are allowed] 2,500 free requests per day, calculated as the sum of client-side and server-side queries. … Premium Plan customers: [receive a] shared daily free quota of 100,000 requests per 24 hours; additional requests applied against the annual purchase of Maps APIs Credits. 50* server-side requests per second. … These limits are enforced to prevent abuse and/or repurposing of the Google Maps Geocoding API, and may be changed in the future without notice. Additionally, we enforce a request rate limit to prevent abuse of the service. If you exceed the per-day limit or otherwise abuse the service, the Google Maps Geocoding API may stop working for you temporarily.
