Project ID 0 is the default project that loads automatically when no project ID is passed in the unlayer.init() function. This fallback project is intended mainly for testing, quick demos, or basic editor usage without a full project setup.
For users operating under Project ID 0, the usage limit is:
10,000 views or
1 GB of bandwidth
within a rolling 24-hour period.
If this limit is reached, requests may be temporarily restricted until the usage resets. For production environments or higher traffic, it’s recommended to specify your own project ID to avoid these constraints.
