Zernio vs Upload-Post
Zernio is an API for 16 social platforms plus ads, an inbox, SMS and WhatsApp. Upload-Post is a posting API for 22 platforms, built around video uploads, with a hosted MCP server. We make a third option, yeetpost, so we list it in the last column and say where it is narrower.

| Brand voice | Not mentioned on the pages we read. | Not mentioned on the pages we read. | Saved on each connection with set_voice. The agent reads it with get_brand before it writes, so posts come out on brand without a new brief. |
| Image cards | Not mentioned on the pages we read. | A video editor API (FFmpeg, 3,000 minutes a month on the $118 plan) and an AI Shorts Uploader that writes titles and hashtags per platform. Rendering HTML into an image card in a saved brand look is not mentioned. | draw_card writes an image card for a post itself, in the connection's saved look: your colors, fonts and logo, with the post's own numbers on it (POST /posts/{postId}/card). render_image is the path where the agent writes the HTML. |
#Which one to pick
Zernio suits you if you need a platform we do not have, or ads, an inbox, SMS or WhatsApp in the same API.
Upload-Post suits you if you publish video to TikTok, Instagram and YouTube from n8n, Make or your own code, and you want one API for 22 networks.
yeetpost suits you if an agent runs a brand on LinkedIn, X, Bluesky, Discord, Telegram or Mastodon and you want a saved voice, image cards drawn from a saved look and queues behind a hosted MCP server. It is narrower than both of the others on platforms, and we say so in the table.
