{"name":"social-image-pack","description":"Build a social-ready creative package, image, caption, and keyword ideas, in one paid call instead of three. Composite: one call runs image-generate + rewrite-tone + keyword-suggest in parallel, sizing the image to the target platform and writing a caption and discovery keywords to match. Send a prompt plus platform, audience, and tone; get back a hosted image URL, a short caption, keyword suggestions, and per-component timing so you can tell if any leg degraded. Use it as a social creative bundle, campaign image generator, or post image plus caption API.","price":"$0.04","method":"POST","input_schema":{"properties":{"prompt":{"type":"string","description":"Visual concept or campaign idea.
