ChatGPT Ads API: Run ChatGPT Ads From Claude or Your Own Code

ChatGPT now shows ads, and advertisers manage them in ChatGPT Ads Manager. If you’d rather run them from an API, or ask Claude to “launch a $20/day ChatGPT ad for my pricing page”, Creator OS supports ChatGPT ads in its Ads add-on, next to Meta, Google, TikTok, LinkedIn and X. This post covers how to connect, what an ad needs, and the current limits of the network.

ChatGPT ads through Creator OS

Connecting

ChatGPT ads don’t use a sign-in page. You create an API key in ChatGPT Ads Manager and give it to Creator OS once (on the Ads page, or POST /v1/connect/openai/ads). One key is one ad account. At the time of writing, ChatGPT ads are open to US-based businesses only.

What a ChatGPT ad needs

Headline: 3 to 50 characters.
Body: up to 100 characters.
Image: a static image (an image card ad).
Link: where clicks go.

Goals: traffic, awareness and conversions. Targeting is by country. The Conversions API is supported, so you can send conversion events back.

From Claude

With the Creator OS MCP server connected and the add-on on:

“Create a ChatGPT traffic ad for creatoros.ca/claude: 3 headline options under 50 characters, pick the best, $20 a day for a week in the US. Create it paused and show me.”
“How did my ChatGPT ads do this week compared with Meta?”
“Pause every ChatGPT ad with a CTR under 0.3%.”

Every create is dry-run first, budgets are confirmed with you, and ads are created paused.

Current limits to plan around

Metrics refresh once a day and include impressions, clicks and spend only.
No creative edits after launch. To change an ad, create a new one (pause the old).
No boosting: there are no organic ChatGPT posts to boost.
No audiences beyond country targeting for now.
Who sees them: ChatGPT Free and Go users in the US, Canada, Australia and New Zealand.

Why it’s worth testing

People ask ChatGPT for recommendations while they’re deciding. Ads there sit next to high-intent questions, and early networks are usually cheaper before everyone piles in. Start small, measure clicks to signups with a trackable link, and compare against your Meta and Google numbers in the same report.

Also in the add-on

Meta Ads MCP, Google Ads MCP, TikTok Spark Ads, LinkedIn and X ads. One add-on at $19.99/month, no percentage of spend. Full details in the Ads guide.
