Post to X without thedeveloper account or OAuth setup
The official X API still means a developer application, an OAuth app you set up yourself, and either $200/mo Basic or metered pay-per-use billing. OpenTweet lets you post, schedule, and automate X from one API key or an MCP server, for $19.99/month.
7-day free trial. No X developer account needed.

One call instead of an OAuth project
Posting a tweet through OpenTweet is a single authenticated request. No signing, no token refresh, no developer portal.

Which one is right for you
Use the raw X API if
- You need to read the firehose or large volumes of other users tweets
- You are building a full Twitter client or analytics product
- You want direct, low-level control and can maintain it
Use OpenTweet if
- You want to post, schedule, and automate from your own account
- You are wiring an AI agent or app to X and want it live today
- You would rather pay a flat fee than manage X API billing and tokens
Flat $19.99/month
No per-call billing to track, no surprise overages.

Frequently asked questions
Do I need an X developer account to use OpenTweet?
No. You connect your X account once with a normal login, then OpenTweet gives you an API key. There is no developer application, no approval wait, and no OAuth code to write.
How much does the X API cost compared to OpenTweet?
The official X API offers a $200/month Basic tier or metered pay-per-use billing, with higher tiers running into thousands per month, and it still requires a developer account and your own OAuth app. OpenTweet starts at $19.99/month flat, needs no developer account, and has no per-post fees. Pro includes 1 link post a day, with more on Advanced ($29/month, 10 a day) and Agency ($49/month, 20 a day).
Can my AI agent or bot post through OpenTweet?
Yes. That is the main use case. Your agent calls one REST endpoint or uses the OpenTweet MCP server (works with Claude, Cursor, OpenClaw, and any framework). Posting a tweet is a single API call.
When should I use the raw X API instead?
Use the raw X API if you need to read the firehose, pull large volumes of other users tweets, or build a full Twitter client. OpenTweet is built for posting, scheduling, threads, media, and automation from your own account.
What can I do through the OpenTweet API?
Create tweets and threads, schedule and publish, upload or AI-generate media, run an evergreen queue, manage multiple X accounts, and read your own analytics. All without touching the X API directly.
