What is the Ghost API?

The Ghost API is a public REST interface to campaigns, contacts, segments, and automation workflows. Auth is handled with an API key in a header. Official SDKs cover node, which keeps boilerplate to a minimum.

Typical builds: scripts that sync subscribers from your product database, engagement dashboards that combine open rate with revenue attribution, and cron jobs that pause underperforming campaigns automatically.

For agent workflows specifically, the community MCP server is usually less code than the REST API. The API still wins for scheduled jobs, dashboards, and anything outside an LLM-driven flow.

How much does the Ghost API actually cost?

Verify on docs

Ghost 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.

Ghost also has an MCP server

If you're wiring Ghost into Claude / Cursor / Codex, the MCP server is usually less code than the REST API.

What you can build with the Ghost API

Three personas, three different shapes of build. Pick the row that matches how you actually ship.

SOLO DEV / FOUNDER

Glue Ghost into your daily workflow

  • Pull a digest of campaign performance into your morning Slack
  • Trigger a one-off backfill when something looks off
  • Pipe data into your own SQLite for ad-hoc queries
Effort: A weekend, one Node or Python script
AGENCY / CONSULTANT

Sell Ghost reporting at scale

  • White-label Ghost data into client-branded dashboards
  • Run scheduled multi-account reports without logging into the Ghost UI
  • Cross-reference with the rest of the client's stack (CRM, analytics, ad spend)
Effort: 1-2 weeks, hits multi-tenant auth quickly
IN-HOUSE ENGINEER

Production pipelines for Ghost

  • Real-time sync into your warehouse on a cron
  • Custom alerts the dashboard's built-in alerting can't express
  • Backfill + idempotency handling for Ghost data older than the dashboard exposes
Effort: Multi-week project, expect rate-limit tuning

Quickstart template

# Starter template — endpoint paths and SDK package names come from
# the Ghost API docs: https://docs.ghost.org/content-api/

curl -X GET "https://api.ghost.org/<your-endpoint>" \
  -H "Authorization: Bearer $YOUR_API_KEY" \
  -H "Accept: application/json" | jq .

Template only. Endpoint paths, exact base URL, and auth header format come from docs.ghost.org/content-api.

Limits and gotchas

  • No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
  • Official SDKs: node. Use them to skip auth boilerplate and get type safety.
  • Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
  • No-code fallback: Zapier and Make.com cover the common triggers if you want to skip writing API code for simple flows.

Agent-readiness verdict

Moderate agent-fit with community support but limited automation depth. Ghost has a documented API with Node.js SDK and an active community MCP server, giving agents read/write access to content and members. The absence of webhooks, structured outputs, and an official OpenAPI spec means agents can't react to platform events or reliably parse complex responses, limiting real-time automation workflows.

Ghost API FAQ

Does Ghost have a public API?+
Yes — REST API at docs.ghost.org/content-api, auth via api-key.
What auth does the Ghost API use?+
API key in a header — simplest to integrate, no OAuth dance.
Does Ghost have official SDKs?+
Yes — official SDKs for node.
Should I use the API or the MCP server for Claude / Cursor / Codex?+
Prefer the MCP server for agent workflows — it's less code and pre-handles auth flows. Use the REST API for scheduled jobs, dashboards, and anything outside an LLM-driven flow.
