The ApiTwitter Alternative
That Doesn't Need Your Browser Cookies
ApiTwitter requires your browser cookies for every write operation. They expire randomly, break when X pushes updates, and violate X's ToS. Zernio uses official OAuth. Connect once, post forever.
No credit card required • Official OAuth • 15 platforms, not just X
// ApiTwitter: paste browser cookies that expire randomly
// { "ct0": "abc123...", "auth_token": "def456..." }
// Hope X doesn't invalidate them today.
// Zernio: Official OAuth. Connect once. Done.
const response = await fetch(
"https://zernio.com/api/v1/posts",
{
method: "POST",
headers: {
Authorization: "Bearer YOUR_API_KEY",
"Content-Type": "application/json",
},
body: JSON.stringify({
text: "Posted via official OAuth, not scraped cookies.",
platforms: ["twitter", "linkedin", "instagram"],
// One call. 15 platforms. No cookies.
}),
}
);The Fatal Flaw: Cookie-Based Auth
Posting a tweet via ApiTwitter requires your ct0 and auth_token browser cookies. Change your password? Dead. X security update? Dead. Unusual activity detected? Dead. SocialData.tools, a similar scraping service, was already shut down by X.
“"We don't currently have published rate limits" — ApiTwitter. No rate limits, no SLA, no ToS, no team info. A black box.”
Zernio: Official OAuth. Connect once, post forever.

Cookie Auth = A Ticking Time Bomb
Change your X password? Cookies die. X security update? Cookies die. Unusual activity? Cookies die. Your integration breaks at 3 AM and you won't know until users complain.
SocialData.tools was shut down by X. The creator's personal account was deleted. This isn't hypothetical.
Key Difference
Official OAuth vs Cookie Scraping
Cookies expire. OAuth doesn't.
ApiTwitter: Cookies
- ✗Extract ct0 + auth_token from browser
- ✗Cookies expire unpredictably
- ✗Manual re-extraction each time
- ✗X can invalidate any time
- ✗Violates X's ToS
- ✗Similar services shut down by X
Zernio: OAuth 2.0
- ✓User authorizes once
- ✓Tokens auto-refresh
- ✓Zero manual intervention
- ✓X-approved auth method
- ✓Fully ToS compliant
- ✓Built on official APIs
Real-World Scenarios
SaaS scheduling product
You're building a tool where users connect their X accounts to schedule posts.
Winner: Zernio
Can't ask end users to paste browser cookies. OAuth is the only viable path.
Read-only analytics dashboard
You need to pull public tweet data and follower counts.
Either works
ApiTwitter's read-only endpoints don't need cookies. Both are viable here.
Bot that auto-replies to mentions
A support bot that reads mentions and posts replies.
Winner: Zernio
Write operations on ApiTwitter need cookies. One expiry = bot goes silent.
Cross-platform posting
Post to X, Instagram, and LinkedIn simultaneously.
Winner: Zernio
ApiTwitter is X-only. You'd need 3 vendors vs. one Zernio API call.

Common Questions
- What is ApiTwitter?
- └An unofficial X/Twitter API proxy with 56 endpoints. Reads use an API key; writes require browser cookies (ct0 + auth_token). X/Twitter only.
- Why are browser cookies a problem?
- └They expire unpredictably. Password changes, security updates, or X detecting automation all kill them instantly. No programmatic refresh. For multi-user production apps, this is untenable.
- Can X shut down ApiTwitter?
- └Yes. It scrapes X's internal APIs, violating their ToS. SocialData.tools was already shut down this way, and the creator's X account was deleted.
- How does pricing compare?
- └ApiTwitter: $0.14/1K calls (X only). Zernio: flat monthly from $0 (free tier) with 15 platforms. Predictable at any volume.
- Why not use the official X API directly?
- └Official X API: $100/mo (Basic) to $5,000/mo (Pro), very limited. Zernio handles OAuth, rate limits, retries, and token refresh for you, plus 14 more platforms.
- Does ApiTwitter support other platforms?
- └No. X only. Need Instagram, TikTok, LinkedIn? More vendors. Zernio: 15 platforms, one key, one bill.
