WHY POSTZEN?

PostZen vs. X API

X API brings its own authentication, rate limits, media rules, and maintenance. PostZen replaces it with one predictable integration.

PostZen

2.3M+ posts

2,000+ developers
  • Simple API key authentication - no OAuth complexity
  • We handle rate limits automatically with smart queuing and retries
  • Upload media directly to us - we host and optimize it for you
  • Zero maintenance - we handle all API changes behind the scenes
  • One integration for 10 social platforms with identical patterns

X native workflow

  • Threads and media notes drift across tools
  • Reviewers cannot see the campaign plan from X alone
  • Publishing status sits away from the content calendar
  • Last-minute changes are hard to coordinate
  • Separate workflows are needed for every platform

    POST to /v1/posts with X selected and your content or media. Done.

CODE EXAMPLE

Create a Post on X via API

One POST request to /v1/post — send a file or a public URL

const response = await fetch("https://api.postzen.dev/v1/posts", {
  method: "POST",
  headers: {
    "Authorization": "Bearer POSTZEN_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    platforms: [{ platform: "x", accountId: "your-x-account-id" }],
    content: "Building the future with calm campaign workflows",
    mediaItems: [{ url: "https://cdn.example.com/launch-image.jpg" }],
    scheduledFor: "2026-06-15T19:00:00Z",
    tags: ["launch", "x"]
  })
});

const result = await response.json();
console.log("Scheduled successfully:", result.post._id);

Frequently asked questions

Still have questions?

How much does the X API cost for posting?

X API pricing changes frequently and can include usage-based access, legacy paid tiers, or enterprise plans depending on your account. PostZen is free up to 2 accounts, then pay only for what you use beyond that.

Why use PostZen as an X API alternative?

X's API can require paid access, developer portal approval, media upload handling, thread chaining, and ongoing API maintenance. PostZen abstracts that complexity with one simple endpoint for scheduling posts on X and other supported platforms.

Can I post X threads via API?

Not yet. Each API call publishes a single post to X today. Thread chaining is on our roadmap.

Does PostZen support X DMs?

Not yet. PostZen focuses on publishing and scheduling today. DM support is on our roadmap.

Can I post images, videos, and GIFs?

Yes. PostZen supports all X media types: images, videos, and GIFs. We handle the multi-step media upload process that X's API requires.
