Pricing model

Caroush's API/MCP entitlement requires paid Creator, Growth, or Pro access; the trial excludes it, and normal credits and feature limits still apply. Buffer publishes request quotas by plan, Publer lists API access on Business, Postiz includes API and webhooks in paid tiers, and Ayrshare and Zernio market developer-focused usage models.

Common questions.

A practical starting point before you validate your exact channels, permissions, team size, and publishing volume.

01

What should I test before choosing a scheduling API?

Test OAuth, media upload limits, supported post types, scheduling behavior, webhook reliability, error detail, retries, rate limits, and the review requirements of each social platform.

02

Does Caroush offer a public developer API?

Caroush publishes documentation for its MCP API, including tool schemas and client setup. It uses named MCP tools over HTTP with OAuth authorization. Access requires an active paid Creator, Growth, or Pro subscription, and publishing or scheduling requests require browser approval. Review the current setup guide and verify your connection before building against it.
