PostZen

The ApiTwitter Alternative With Official OAuth, Not Cookies

ApiTwitter publishes to X with your browser session cookies and a proxy you bring. PostZen connects X through official OAuth 2.0, refreshes tokens for you, and posts to nine other networks with the same request.

Why Switch?

Why PostZen vs ApiTwitter?

PostZen API

PostZen

  • Official OAuth 2.0 for X

    Users authorize PostZen through the X developer platform. No cookies to extract, no proxy to rent, and tokens refresh without your involvement.

  • Scheduling, drafts, and queues

    Publish now, schedule with scheduledFor, save drafts, fill recurring queue slots, or import a month of posts from CSV.

  • Ten networks from one request

    The same JSON body posts to X, Instagram, LinkedIn, Facebook, Threads, YouTube, TikTok, Pinterest, Bluesky, and Telegram.

  • Media handled for you

    Presign an upload or pass a URL. PostZen re-hosts the file and enforces each network’s size and format rules before publishing.

  • Published SLA and rate limits

    A 99.97% uptime SLA and 60 to 2,000 requests per minute by plan. Every post reports its status and platform post ID.

ApiTwitter

  • Writes need your cookies and a proxy

    Every post, like, follow, DM, and list change runs on an auth_token and ct0 pair you copy from a browser session, plus a proxy URL you supply. ApiTwitter provides neither.

  • Sessions break without warning

    A logout, password change, or X security check invalidates the cookie. Nothing refreshes it. Your publishing stops until someone logs in and copies new values.

  • Outside X’s developer platform

    X’s terms route automation through its developer platform. Cookie-driven posting sits outside it, and ApiTwitter’s own docs warn that fast posting can trip X’s automation defences.

  • X only, no scheduling

    56 endpoints all target X. There is no scheduledFor, no drafts, no queue, and no second network. Timing and retries are your code.

  • Free tier reads at one request per 5 seconds

    With a $0 balance reads are capped at 0.2 requests per second. Any top-up from $10 unlocks 3 per second, and 100 per second needs a balance above $200.

FAQ

Common questions

Still have questions?

What is ApiTwitter?

ApiTwitter is a third-party X (Twitter) REST API with 56 endpoints sold on prepaid credits. Read endpoints such as profiles, followers, timelines, and search run on a pool of X accounts ApiTwitter operates. Write endpoints such as posting, liking, following, and DMs run on session cookies and a proxy you supply.

How does ApiTwitter authenticate posts to X?

You copy the auth_token and ct0 cookies from a logged-in browser session, pass them with every write request along with a proxy URL, and ApiTwitter replays the action as that account. ApiTwitter does not provide cookies or proxies. PostZen instead sends the user through X’s official OAuth flow and stores a refreshable token.

Is ApiTwitter cheaper than PostZen for posting?

Per post, yes. ApiTwitter charges 225 credits per write, which is $2.25 per 1,000 posts, while X’s official rate that PostZen passes through is $0.015 per post, or $15 per 1,000, on top of the plan fee. The trade is that ApiTwitter’s price excludes the proxy you rent and the time spent replacing expired cookies, and PostZen’s plan includes scheduling, media handling, and nine other networks.

What happens when an ApiTwitter session cookie expires?

Writes fail until someone logs into X in a browser and copies fresh cookie values. There is no refresh token. ApiTwitter’s rate-limit docs also note that X may throttle the account behind a cookie and suggest spreading load across more accounts. On PostZen, an OAuth token that stops working shows up as a reconnect prompt for that one account, and everything else keeps publishing.

Does ApiTwitter support scheduling or other platforms?

No. All 56 endpoints target X, and posts publish when you call them. PostZen schedules posts, saves drafts, fills queue slots, imports CSV, and publishes to Instagram, LinkedIn, Facebook, Threads, YouTube, TikTok, Pinterest, Bluesky, and Telegram alongside X.

What does ApiTwitter offer that PostZen does not?

Public X data reads (search, followers, following, timelines, communities, and topics), engagement actions such as likes, follows, retweets, bookmarks, DMs, and list management, X Articles, and a Realtime Stream product that pushes tweets to Telegram, Discord, or webhooks. PostZen is a publishing and scheduling API, not a data API.

Does PostZen charge for X API usage?

PostZen passes X’s own per-request rates through with zero markup: $0.015 per post, $0.20 per post containing a URL, and $0.005 to $0.01 per read. Connecting an X account requires a card on file for that reason. Plan fees start at $0 for 2 accounts and 20 posts a month.

Can I migrate from ApiTwitter to PostZen?

For publishing, yes. Replace the cookie-and-proxy call with a hosted OAuth connect step per account, then create posts with a platforms array. Media goes through a presigned upload or a public URL. Read, search, and engagement calls have no PostZen equivalent, so keep ApiTwitter for those if you need them.
