For Agents

Read posts, pages, authors, tags, tiers, and site settings from a Ghost publication across 14 endpoints with read-only API-key authentication.

Install Jentic One Beta

Connect the Ghost Content API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Ghost Content API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases

Patterns agents use Ghost Content API for, with concrete tasks.

★ Headless Front-End for a Ghost Site

Teams running Ghost as the CMS but rendering the front end in Next.js, Astro, or another framework use the Content API to fetch posts, pages, and metadata at build or request time. The list endpoints support filtering by tag and author so the front end can build category and author archives without indexing the full content set.

List the latest 10 posts including their tags and author, then render them as a homepage feed.

Mobile App Reader

Mobile apps that show a publication's articles to subscribers fetch posts and pages from the Content API, cache them locally, and render with native typography. The /tiers endpoint exposes membership levels so the app can gate premium content rendering against the user's subscription state determined elsewhere.

Fetch the 50 most recent posts and the tier list, then cache them for offline reading.

Newsletter and Aggregator Feeds

Aggregators and newsletter tools poll the Ghost Content API for new posts on a schedule and fan them out to other channels. Filter by published_at to fetch only posts since the last poll, and use the slug-lookup endpoint to deep-link back to the canonical post URL on the Ghost site.

List posts published in the last 24 hours and post their titles and links to a Slack channel.

AI Agent Content Discovery

An AI agent answering questions about a Ghost publication can search posts and pages by tag or slug, retrieve full content including author and tag metadata, and cite the canonical URL. Through Jentic the agent finds the right list or lookup endpoint by intent and the Content API key stays in the encrypted vault.

List posts tagged 'pricing' and return the title, slug, and excerpt of each.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Ghost Content API keys are stored encrypted in the Jentic vault. Agents receive a scoped invocation capability — the raw key never enters the agent's context, which is meaningful because the key rides in the URL query string and would otherwise leak to logs.

Intent-based discovery

Agents search by intent (e.g. 'list ghost posts' or 'get a ghost post by slug') and Jentic returns the matching operation with its full query-parameter schema for direct execution.

Time to first call

Direct Ghost Content API integration including key handling, caching, and slug resolution: half a day to one day. Through Jentic: under 1 hour — search, load, execute.

FAQs

Specific to using Ghost Content API through Jentic.

What authentication does the Ghost Content API use?

The Content API uses an apiKey scheme — the key is passed as a query parameter named 'key' on every request. Through Jentic the key is stored encrypted in the vault and the agent receives a scoped invocation capability, which avoids the key leaking into client-side request logs.

Can I retrieve a Ghost post by its slug?

Yes. GET /posts/slug/{slug}/ returns the post matching the slug, including title, content, tags, authors, and published_at. This is the canonical way to resolve a URL slug back to the post record without scanning the full list.

What are the rate limits for the Ghost Content API?

The spec does not declare specific rate limits. Self-hosted Ghost instances inherit limits from the deployment; Ghost(Pro) hosted publications apply per-account quotas. Production front-ends should cache responses (most posts change rarely) and implement backoff on 429 responses.

How do I list posts from a Ghost site through Jentic?

Search Jentic for 'list ghost posts'. Jentic returns the GET /posts/ operation with its query-parameter schema (filter, order, include); load it, set the filter you want, and execute. The response contains the post array along with pagination metadata.

Does the Ghost Content API allow creating or updating posts?

No. The Content API is read-only. Creating, updating, or deleting posts and pages requires the separate Ghost Admin API which uses a different authentication scheme and exposes write operations.

Can I read membership tiers from the Content API?

Yes. GET /tiers/ lists the membership tiers configured on the publication along with their pricing and benefit text, which is what front-ends use to render the subscription paywall component.
