This API uses the combination of a namespace and a key to identify a counter. The namespace is a string that identifies the application or service that is using it. This should be something like your domain or company name. The key is a string that identifies the counter within the namespace. This should be something memorable.
API key is required to create and access counters.
Include your API key in the request headers:
X-API-Key: your_api_key_here
If you need an API key, you can create one here.
Important: Keep your API key secret and secure. Anyone with your API key can access your counters.
Namespaces created before May 6th 2025 can be accessed without authentication
