Kiln Publish Page Takedown

Use this endpoint when you need to programmatically remove or unpublish a specific ephemeral page previously created via Kiln Publish on Fluidrack, especially in automated agent workflows where content has a defined lifecycle. Prefer this over manual deletion when integrating takedown into pipelines that handle content expiry, error recovery, or post-task cleanup.

• Page ID not found — returns error if the ID does not correspond to an existing page
• Reason string too short — returns validation error if reason is under 10 characters
• Page already taken down — may return an error or idempotent success if the page was previously removed
• Unauthorized — if the caller does not have permission to take down the specified page
• Payment failure — x402 payment of $0.01 USDC not completed, request rejected
