Zernio review
Low-cost access to publishing, analytics, engagement, and account management across 16 platforms.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Zernio provides a REST API for developers adding social media functionality to applications. Its scope covers publishing and scheduling posts across 16 social platforms, OAuth-based account connections, post and aggregated performance analytics, webhooks for publishing and account events, comments, direct messages, inbox conversations, and profiles for organizing connected accounts. It is suited to teams building multi-network workflows through web or API access, especially when low-cost account-based pricing matters.
The pricing structure is graduated by connected account and billed monthly. The 1 to 2 connected accounts tier is free, includes all API features and unlimited posts, and requires no credit card. From 3 to 10 accounts, pricing is $6 per connected account per month; 11 to 100 accounts cost $3 per account per month; 101 to 2,000 accounts cost $1 per account per month; and 2,001+ accounts also cost $1 per account per month with no cap on connected accounts. Paid tiers include all API features, unlimited posts, and all 16 platforms. The published limits show 60 requests per minute for 0–2 connected accounts and 600 requests per minute for the 3–10 account tier, with separate per-second limits for analytics endpoints.
Zernio’s ecosystem fit is a central strength for developers that want several implementation paths. It offers API documentation, official SDK support, integrations with n8n, Make, Zapier, OpenClaw, and Vercel Chat SDK, plus AI features. Account management, webhooks, analytics, and inbox capabilities extend the product beyond basic post publishing. Choose Zernio for a consolidated API and graduated pricing across many social networks. Consider an alternative if a longer operating history, conventional named plans, or a different request-limit model is more important than broad API coverage.
