Elena Zarino Web Developer

I integrated Zernio's API and MCP into my Claude Copilot and Claude Code setup, and it filled a gap I'd been working around for a while.
Leon Founder, Moving Monkey

We're integrating Zernio into our coaching app's WhatsApp inbox and love how clean the SDK is. Thank you for that.
Justin Founder, StandoutResults

We'd been using the HighLevel API for social posting, every post stuck in draft, a lot of hassle. Zernio has been a breeze to work with.

FAQ

Frequently asked questions

What does it cost to get started?

Nothing. The first 2 accounts are free, every billing period, with no credit card to sign up, no setup fee and no contract. You only start paying when you connect a 3rd account.

How does pricing scale?

Graduated, per connected account. The first 2 accounts are free. Accounts 3 to 10 cost $6/each. Accounts 11 to 100 cost $3/each. Accounts 101 and up cost $1/each, with no cap, fully self-service at any scale. Volume discounts apply automatically as each tier's rate applies only to the accounts inside that range, so your effective rate drops as you scale.

What counts as an account?

One social media profile on one platform equals one connected account. For example: one Instagram account, one TikTok account, and one LinkedIn page = 3 accounts.

What's included with every account?

Every paid account includes scheduling and publishing, analytics, DMs, comments and reviews, ads management, and webhooks across the platforms that support each capability. No add-ons and no upsells, so nothing is gated behind a plan. Two things are metered on usage rather than bundled: managed ads (your first 500 active ads are free, then $0.01 per active ad per month) and X/Twitter API calls, passed through at X's exact rates.

What about X/Twitter API costs?

X/Twitter charges per API call (reads, writes, DM sends). We pass those costs through at exact X rates with zero markup. Every other platform (Instagram, TikTok, YouTube, LinkedIn, Facebook, and so on) is fully included in your per-account price.

What if I have more than 2,000 accounts?

Nothing changes unless you want it to. Self-serve keeps the $1/account rate at any scale, with no cap and no forced sales call. Past 2,000 accounts an enterprise contract is optional: it adds volume discounts, SAML SSO, SCIM, audit logs, a dedicated Slack channel with engineering, and net-30/60 invoicing.

Can I cancel anytime, and do you offer refunds?

Cancel at any time with no fees or penalties; service continues to the end of your current billing period. Billing is metered daily and disconnects are prorated, so you stop paying for an account the day you disconnect it. There are no refunds on usage already billed, but a billing error or an outage on our side is credited back.

Do I need to be a developer to use Zernio?

Zernio is built for developers and teams with technical resources. If you can make API calls, you can use Zernio. We also integrate with no-code tools like n8n, Make, and Zapier.
