How they compare.
SocialAPI.ai
SocialAPI.ai is a unified REST API for reading and responding to comments, DMs, reviews, and mentions across Instagram, Facebook, Google Reviews, TikTok, Threads, and LinkedIn — plus publishing content and an MCP server with 42 tools for AI agents. One API key, one flat monthly price, no add-ons.
Zernio (Late)
Zernio is a social media API supporting 14 platforms including Reddit, Pinterest, Bluesky, Telegram, and Snapchat. Publishing is included in all plans, but inbox (comments + DMs) and analytics are paid add-ons ($10–$1,000/mo depending on plan). They offer 8 official SDK libraries and a limited MCP server for Claude Desktop. The product appears relatively new with limited third-party review coverage.
Simple by design.

SocialAPI.ai includes inbox access on every plan — even the free Hobby tier. At comparable feature sets, SocialAPI.ai is 1.3–2.4x cheaper once Zernio’s add-ons are factored in.
