generate_post_cover

Active

declared in 1.0.0

Generate an AI image and attach it as a post's featuredImage. Submits a kie.ai job, polls until complete, copies the result into the canonical post-asset R2 folder, and writes the public URL onto the post. Costs credits (see list_image_models). On poll timeout, the job continues — call attach_post_cover_from_job(postId, jobId) once it finishes to attach without paying again.
