Create an OpenSink account

OpenSink uses magic links — no passwords required.
  1. Sign up at https://opensink.com
  2. Create your first workspace
  3. You’ll land directly in your dashboard
That’s it.
When you sign up, OpenSink automatically creates a default Sink for you.You can start sending data immediately.

Copy the example command from your dashboard

Your dashboard shows a ready-to-run example command.It already includes:
  • your API token
  • your default Sink ID
  • a valid payload
It looks like this:
curl -X POST 'https://api.opensink.com/api/v1/sink-items'   -H 'Content-Type: application/json'   -H 'Authorization: Bearer YOUR_API_TOKEN'   -d '{
    "sink_id": "YOUR_SINK_ID",
    "title": "My first item",
    "body": "This is the item body",
    "type": "event",
    "url": "https://example.com",
    "fields": {
      "foo": "bar"
    }
  }'
Just copy it and run it.
This command sends a single Item to OpenSink.OpenSink:
  • authenticates the request
  • writes the Item to your Sink
  • indexes it for search
  • makes it visible in the UI

See the result instantly

Go back to the OpenSink UI.You’ll see:
  • your Item listed immediately
  • timestamps and metadata
  • searchable content
You’ve just completed the core OpenSink loop:
Code → OpenSink → UI

​
That’s already enough to be useful

At this point, you have:
  • a workspace
  • a Sink
  • a secure API token
  • a place to store and inspect information
This works with:
  • AI agents
  • automation scripts
  • background jobs
  • any system that can make an HTTP request
