Short verdict

Developers and agencies who want to build posting to many social channels into their own app or AI agent.
Less suited to
Anyone who wants everything in the EU: the main database is in London and some sub-processors are outside the EU.
Key facts
- Two accounts free, then from $6 per account
- Main database in London (UK), not in the EU
- Data processing agreement is in the terms
What is Zernio?
Zernio is an API from Zernio Software SL in Palamós (Spain). You schedule and publish posts, reply to comments and messages and retrieve statistics for social channels such as Instagram, TikTok, LinkedIn and YouTube, and you manage ads. There is a hosted MCP server, so an AI agent can post directly.
According to the list of sub-processors, the main database is in London (AWS eu-west-2); the UK is not part of the EU. Media files are in Western Europe and some services, such as logging, run in the US; Zernio names the Data Privacy Framework or standard contractual clauses per service. The data processing agreement is part of the terms and applies without a signature.
Good: the first two accounts are free, and you pay per connected account instead of per plan. All features are in every account.
Less good: prices are in dollars and the main data is outside the EU. There is no trial of the paid part, only the free start.

Data in the EU: No
An API you build into your product often processes your customers' data. If that data is outside the EU, you have to explain that in your own privacy statement and data processing agreement.
More about data in the EU →Data processing agreement: Yes
If you build an API into your product, the vendor becomes a sub-processor for your customers. Without a data processing agreement you cannot cover that chain.
