How much does the Postiz API actually cost?
Postiz publishes an API, but per-tier gating wasn't extracted automatically.
- Most likely scenario: API access is either included in all paid plans, or it's gated to higher tiers and we need to verify on the live docs page.
- Until verified, treat the question "which plan unlocks the API" as open. Don't budget on the assumption it's free with the cheapest paid plan.
API at a glance
Postiz also has an MCP server
If you're wiring Postiz into Claude / Cursor / Codex, the MCP server is usually less code than the REST API.

Quickstart template
# Starter template — endpoint paths and SDK package names come from # the Postiz API docs: https://docs.postiz.com/public-api/introduction curl -X GET "https://api.postiz.com/<your-endpoint>" \ -H "Authorization: Bearer $TOKEN" \ -H "Accept: application/json" | jq .
Template only. Endpoint paths, exact base URL, and auth header format come from docs.postiz.com/public-api/introduction.
Limits and gotchas
- No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
- No official SDK detected. Plan on hitting the API directly with your HTTP client of choice.
- Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
Agent-readiness verdict
Strong agent fit, and unusually open for an indie tool. Postiz ships a first-party official MCP server (api.postiz.com/mcp, OAuth2) alongside a documented public REST API with a real OpenAPI 3.1 spec, an official Node SDK, webhooks, and native Zapier, Make, and n8n. An agent can publish, schedule, and pull analytics across 27 platforms over MCP or plain REST with little glue code. Being open-source, you can also self-host the whole stack, which most rivals don't allow.
