Verification path
Review /pricing before checkout: choose GPT-5.5 XHigh at $19/week or an eligible $59 first month followed by $69/month, or GPT-5.6 Sol at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month. Then use the setup email and authenticated GET /v1/models before a small endpoint check within the 4-connection boundary.
Decision summary
Best fit
GPT-5.5 XHigh costs $19/week or an eligible $59 first month followed by $69/month. GPT-5.6 Sol is available at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month.
Not a fit
Not ideal for workloads requiring instant key delivery, unsupported SLA promises, or high-concurrency production traffic.
Next step
Review /pricing, choose the matching package family, then use the setup email and authenticated GET /v1/models to verify the delivered model ID before validating endpoints.
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 work continues, move from $19/week to eligible first-order $59 then $69/month GPT-5.5 XHigh. Choose GPT-5.6 Sol at $69 then $89/week or $179 then $199/month. One welcome price is available per account.

FAQ
Is Weekly enough for an agency demo?
Weekly can be enough when the demo is scoped, setup is delivered before the call, and the workflow stays within 4 concurrent connections.
Can I wait until the meeting to buy?
No. Manual delivery usually takes 10 minutes to 5 hours, so purchase before the demo window starts.
What should a demo avoid?
Avoid private client secrets, regulated data, long parallel agent runs, and unsupported claims about official OpenAI affiliation.
