Setup steps
Step 1
Buy before the demo window
Complete checkout before the client call because setup is manually delivered and usually takes 10 minutes to 5 hours.
Step 2
Prepare the smallest useful demo
Build a narrow workflow with sample data, one clear success path, and a fallback state if endpoint or auth checks fail.
Step 3
Verify endpoints before presenting
Run /v1/models, one tiny chat/completions request, and any image or embedding check the demo depends on.
Step 4
Move recurring work to Monthly
If the client continues after the demo week and 4 concurrent connections remain enough, switch planning to Monthly.
