TwittrAPI vs OpenTweet: Posting to X from Code, Prices, Limits (2026)

OpenTweet is a posting layer for X built for AI agents: a scheduler, a REST API, an MCP server and a CLI, for a flat monthly fee. TwittrAPI is a data API that also has account actions: post, reply, like and DM from your own X account, billed per call.

We run TwittrAPI. OpenTweet details below come from its own pages, checked on 20 October 2026. Each number links to its source.

What a post costs

OpenTweet charges a flat fee, so the price of one post depends on how much of the plan you use. If you use every post the plan allows, that is $0.033 on Pro, $0.0097 on Advanced, $0.0054 on Agency per post, every daily post used^{as of Oct 2026} (30 days a month). Posts with links have their own monthly allowance, which works out at $0.67 on Pro, $0.097 on Advanced, $0.082 on Agency per post with a link, every link post used^{as of Oct 2026}. Beyond that, OpenTweet sells more link posts as an add-on (link credits)^{as of Oct 2026}.

On TwittrAPI a post is one call, with or without a link, so 1,000 posts cost $0.065 to $0.10. Uploading an image is one more call. You also pay for your own proxy.

For the official X API, the reference point both services compare against: $0.015 per post created^{as of Oct 2026} and $0.200 per post with a URL^{as of Oct 2026}. Our guide to what posting to X from code costs works through 1,000 posts a month, with and without links, for these and two other services.

Where OpenTweet is the better fit

Official API and OAuth. You connect your account once through X's own sign-in. No session cookie leaves your browser, and no proxy is needed.
Inside X's rules for automation. Posting through the official API on an account you authorized is the route X supports. Our account actions use your web session instead; X can limit or suspend accounts that post, follow or like automatically, and our session docs say so.
A scheduler you can see. Calendar, threads, evergreen queue and AI writing, so people can review what an agent queued.
Cross-posting to Bluesky and LinkedIn from the same draft.
Managed agent posting. a hosted MCP server with 43 tools, a REST API and a CLI^{as of Oct 2026}, ready to connect.

Where TwittrAPI fits better

Volume and links. Each post is one call at the same price, links included, and we set no daily post cap. X's own limits for the account still apply.
Replies, likes, follows and DMs from your own account, one call each.
Reading X: search, timelines, followers, lists, communities and trends, on the same key and balance.
Account monitoring: new posts of any public account by webhook.
Many accounts without a per-plan account limit; each call carries the session of the account it acts for.

Many setups use both: a scheduler on the official API for the brand account, and an API for reading and for actions the official route does not cover.

TwittrAPI is not affiliated with X Corp. or OpenTweet. Reading data needs no X account; account actions use your own X session cookie and proxy. Check whether that fits your compliance requirements before you build on it.

Frequently asked questions

Does OpenTweet use the official X API?

Yes. Its FAQ says it publishes through the official X API; no scraping, no logged-in browser session, no password^{as of Oct 2026}. TwittrAPI account actions do not use the official API; they act through the X session cookie of your own account and your proxy.

How many posts with links does OpenTweet allow?

30, 300, 600 posts with links per month (Pro, Advanced, Agency)^{as of Oct 2026}, and more link posts as an add-on (link credits)^{as of Oct 2026}. During the trial it is 5 link posts in total during the trial (15 for agent and automation accounts)^{as of Oct 2026}. TwittrAPI has no separate link limit: a post with a link is one call like any other.

What does a post cost on each?

On OpenTweet, at full use of a plan's daily posts, $0.033 on Pro, $0.0097 on Advanced, $0.0054 on Agency per post, every daily post used^{as of Oct 2026}. On TwittrAPI, one call: 1,000 posts cost $0.065 to $0.10, plus your proxy.

Can I read tweets or monitor accounts with OpenTweet?

OpenTweet reads your own account's analytics and can search X for posts to repurpose; not a firehose, no monitoring of other accounts^{as of Oct 2026}. TwittrAPI reads public data (search, timelines, followers, lists) and monitors public accounts by webhook.

Can an agent reply to other people's posts?

Not through OpenTweet: agents cannot reply to other people's posts, because of X's API reply rules^{as of Oct 2026}. X's changelog describes the rule: on self-serve tiers, replies through POST /2/tweets only when the original author mentioned or quoted the replying account (since February 23, 2026)^{as of Oct 2026}. TwittrAPI has a reply endpoint, which acts through your own X session rather than the official API.
