For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

High-CTR thumbnails and vertical covers, in a few options to choose from.

Recommended route

• Start with: varg AI (varg-ai) — On varg, one key: gpt_image_2_5 or nano_banana_2_1 for the image, ideogram_v4_5 when the text must be exact — a few credits per option.
• Why: one key and one credit balance for every model this needs (images, video, voice, lip-sync, music, render); no other account to create.
• Alternative: Higgsfield YouTube Thumbnail (higgsfield-youtube-thumbnail) — Truthful, high-CTR thumbnails and covers with consistent faces · Needs: Higgsfield account, Higgsfield CLI (higgsfield auth login)
