Zoosial vs Zernio: which social media API should you use?
October 28, 2026 · Zoosial team
Both Zoosial and Zernio are unified social media APIs: one integration to publish, read messages and comments, run ads and receive webhooks, with the provider handling each network's OAuth, token refresh and app review. They also both ship a remote MCP server so an AI agent can operate the API. They differ in breadth, pricing model, language and regional focus. We built Zoosial, so we have kept this to what each vendor states on its own site as of the date above. Check current prices on zoosial.com/pricing (in Spanish, MXN) and zernio.com/pricing.
At a glance
| Zoosial | Zernio | |
|---|---|---|
| Networks | Facebook, Instagram, WhatsApp, Telegram, Threads, LinkedIn, TikTok, Google (YouTube, Business Profile, Calendar) | 16 platforms, including X, Pinterest, Bluesky, Snapchat, Discord and Slack |
| Ads | Meta and Google | 8 ad networks, including Meta, Google, TikTok, LinkedIn and Pinterest |
| Inbox | Unified inbox for Facebook, Instagram, WhatsApp and Telegram, with webhooks | Unified inbox including WhatsApp, Instagram, Messenger, Telegram and X |
| MCP server | Remote, OAuth 2.1 + PKCE, 60+ tools, included in the free plan | Remote, OAuth or API key, 280+ tools according to its docs |
| Pricing unit | Per profile (a profile groups several accounts); first profile free | Per connected social account; first 2 free |
| Docs language | Spanish guides; the llms.txt contract opens with an English summary | English |
| Regional extras | Mexico: CFDI 4.0 invoicing, SAT data, Apple/Google Wallet, AI voice calls in Mexican Spanish | Not a focus |

A cost example
An agency with 10 clients and 4 social accounts per client (40 accounts in total), at the prices each vendor publishes as of the date above:
| Zoosial | Zernio | |
|---|---|---|
| What is counted | 10 profiles (a profile groups one client's accounts) | 40 connected accounts |
| Math | First profile free; 8 × $95 + 1 × $75 MXN | First 2 accounts free; 8 × $6 + 30 × $3 USD |
| Per month | $835 MXN + VAT (about $45 USD*) | $138 USD |
*At 18.5 MXN per USD as a reference. Because Zoosial charges per profile rather than per account, each extra client with several networks costs less than under a per-account model. In the opposite case, if you build a product where every end user connects a single account and you have hundreds of users, Zernio's per-account price at scale (from the 101st account, $1 USD) is currently lower than a Zoosial profile at that volume.
When to choose Zernio
You need networks Zoosial does not cover (X, Pinterest, Bluesky, Snapchat, Discord, Slack), ads on more than Meta and Google, or English documentation and SDKs for a global product.
When to choose Zoosial
Your users or customers are in Mexico or Latin America and you want Spanish documentation and support. You need an inbox, lead capture and comment-to-DM automation on Facebook, Instagram and WhatsApp. Or you need CFDI invoicing, SAT data or AI voice calls under the same account and API key.

Yes. Both publish a remote MCP server that works with Claude, ChatGPT and Codex. Zoosial's is at https://zoosial.com/mcp and is included in the free plan.
Is there a unified social media API for Latin America?
Zoosial is built in Mexico and focuses on the region: Spanish-language documentation and support, WhatsApp and Meta tooling, and local services such as CFDI invoicing.
Is Zoosial free?
You can start free without a credit card; the first profile is free. AI credits, invoicing, SAT data and voice-call minutes are billed separately.
