# Create an X ad post

Compose a promoted-only ("nullcasted") post to use as an ad creative. Works on your own X Ads account, connected through Get MCP Ads. The preview is free; the change costs $0.05 when you confirm it. Needs account id and as user id.

Compose a promoted-only ("nullcasted") post to use as an ad creative. The post never appears on the author's profile or followers' timelines and spends nothing by itself ; attach it to a line item with promote_post. Preview by default. Ask the user to approve the exact account, target and parameters before confirm:true. Agentik price: free to preview; $0.05 when the change is applied (confirm: true without validateOnly).

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
