AI content engine + headless CMS

Your blog, on autopilot.

Terradium finds your keywords, plans your content calendar, and sets AI agents to research and write SEO articles every day — then publishes them to your own CMS that you pull into your site with a single API call.

  • Researches & writes daily
  • Publishes to your own CMS
  • One API call to your site

The problem

A blog that ranks is a full-time job nobody has time for.

Keeping a blog alive means keyword research, planning a calendar, briefing, drafting, editing for SEO, sourcing images, and wiring it all into a CMS — every single week. Most teams start strong and quietly stop after a month.

The tools don't talk to each other either. Your keyword research lives in one place, your calendar in another, your drafts in a doc, and your CMS somewhere else entirely.

Terradium is one system that runs the whole loop. It finds the keywords, plans the calendar, writes a publish-ready article every day, and ships it to a CMS your site reads with one API call.

How Terradium works

From keyword to live page, on its own.

Set it up once and Terradium runs the whole loop — then publishes to a CMS your site reads with a single API call.

Everything included

One system for the whole loop. One subscription.

Keyword research database

Discover the keywords your niche is searching for, or import an existing SEMrush CSV. Terradium clusters them into article-ready topics.

Self-planning calendar

Topics are laid out on an editorial calendar automatically, so there's always a queue of articles ready to be written.

Daily AI agent pipeline

Four agents — coordinator, SEO research, writer, and improver — research and draft a publish-ready article every day. Resume-aware and multi-language.

Built-in headless CMS + API

Published posts are served from an API-key-gated public content API. Pull them onto any site or framework with a single request.

AI featured images

On-brand hero images are generated per article and stored for you, or upload your own. Styled to your project's look.

Signed webhooks

Prefer to own delivery? Ship each post to your own stack as an HMAC-signed webhook payload, with automatic retries.

Plug it into your site

One API call. Always fresh.

Terradium is a headless CMS — your content lives behind a clean, key-gated API. Read it from your own domain and let your build stay up to date automatically.

fetch-posts.ts
// Pull your published posts onto any site
const res = await fetch(
  "https://api.terradium.io/api/v1/public/content/" +
    projectId + "/posts",
  { headers: { "X-API-Key": process.env.TERRADIUM_KEY } },
);
const { data, pagination } = await res.json();

Integrate via API

Pull posts into your landing page or framework from the API-key-gated public content API — list, by-slug, and categories.

Sitemap + static pages

We recommend a proper sitemap and statically-rendered pages so search engines crawl your content fast.

Scheduled revalidation

Set your site to rebuild or revalidate on a schedule (ISR, a cron rebuild, or a deploy hook) so it refreshes whenever Terradium publishes.

Stay in the loop

Know the moment a post goes live.

Terradium tells you when articles complete, publish, or fail — and when you're close to your quota — wherever you already work.

Slack

Connect with "Add to Slack" and get a ping the moment an article is published, fails, or your quota runs low.

Email

Lifecycle notifications delivered to your inbox — completed, published, and quota events.

In-app alerts

An in-app inbox tracks every content and billing event with read/unread state.

Billing via Polar

Simple subscription billing and a self-serve customer portal, handled by Polar.

Pricing

One plan. No surprises.
