## Which one, for what

### Ghost (C)

Good for: A publication, blog or newsletter where an agent drafts posts and a person or a higher role publishes.

Ahead on:
- Payments & pricing, 50 against 20

Also in its favour:
- Open source

Watch for: No OpenAPI or other machine-readable description of the Admin API was found in the docs or the repository

### Kontent.ai (BB)

Good for: A company already on Kontent.ai, or evaluating it on a trial, that wants an agent to draft, localise, move through workflow and publish structured content with a permission-limited key and an audit trail.

Ahead on:
- Schema & documentation, 74 against 51
- Security & auth, 81 against 56

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Runs on your own machine
- Free to start without a card
- No incidents deducted, where Ghost loses 7 points for them

Watch for: No price is published. The pricing page shows sliders for seats, content types and items and a form that requests a quote

## Verdicts

**Ghost.** A create needs only a title, updates are checked against `updated_at` so a stale write is refused, and a Contributor's staff token can draft without being able to publish. The Admin API has no OpenAPI file and one fixed permission set per integration, and 20 security advisories were published between 3 September and 1 October 2026.

**Kontent.ai.** Management API keys take per-area permissions, environment limits and an expiry from one minute to two years, and changes made with a key are named in the audit log. Rate limits and Retry-After are documented. No price is published, and no OpenAPI file was found. Access starts with a 30-day trial that a person opens in a browser.

## Before you call either

### Ghost

1. Sign a fresh HS256 token for each batch of calls. Decode the hex secret to bytes, set `kid` to the key id, `aud` to `/admin/` and `exp` at most 5 minutes ahead
2. Set `status` to `draft` on every create unless told to publish, and publish later with a PUT that sets `status` to `published`
3. GET the post before each PUT and send its `updated_at` back. Tags and authors in a PUT replace the existing lists
4. Send content as a Lexical JSON string, or add `?source=html` and send `html`. The HTML conversion is lossy unless wrapped in an HTML card
5. Page through lists with `limit` up to 100 and `page`. Since Ghost 6.0 `limit=all` returns 100 items without an error

### Kontent.ai

1. Send `Authorization: Bearer <key>` to `https://manage.kontent.ai/v2/projects/{environment_id}/...`. The Management API must be switched on under Environment settings, General, Enabled APIs first
2. Ask for a Management API key with only the permissions the task needs. Read content alone gives a read-only key, and keys expire after six months by default
3. Stay under 10 requests a second and 400 a minute per environment, send requests one at a time, and wait the seconds in Retry-After on a 429
4. Page lists by passing the `continuation_token` from the response back in the `x-continuation` header
5. Create items with an `external_id` and write with the upsert PUT at `/items/external-id/{id}` so a retry after a lost response does not create a duplicate
6. With the MCP server, call `get-patch-guide` before any patch tool, and use a client that prompts on destructiveHint
