The best social media APIs for AI agents in 2026: 8 compared by price and limits

Disclosure: Enjoy is our product, and it isn’t an API, so it isn’t one of the eight. We checked every option below against its maker’s own pages on November 3, 2026, and if you’re building posting into a product or running it unattended, one of the eight is the better pick.

The best social media APIs, compared

A social media API lets your code or your agent publish to many networks through one connection, so you don’t build and maintain each platform’s integration yourself. All eight here have an MCP server, which is how an agent like Claude Code or Codex reaches them. They differ most in how they charge and in what you still have to do yourself.

Prices are per month as each maker lists them, before tax. A network count is the maker’s own and doesn’t mean every feature works on every network, so check the three or four you need.

Which to pick

• Posting inside a product, for your customers: Ayrshare, Upload-Post from its Professional plan, or Outstand’s Business plan, which says “Reselling explicitly permitted.”
• No budget yet: Zernio for two accounts, Buffer for three, or Upload-Post for 10 uploads a month, without TikTok.
• Many accounts, few posts: Post for Me.
• Many posts, few accounts: Outstand, down to $0.005 a post, or Upload-Post’s unlimited uploads.
• Your tokens on your own server: Postiz, self-hosted.
• DMs, ads and calls beside the posts: Zernio.
• AI-made videos in the same subscription: Blotato.
• Only your own YouTube videos: YouTube’s free API, or Enjoy.

Ayrshare

Best for: products that post on behalf of many customers.

Ayrshare’s plans are sized by social profile, and from Launch up they “Automate posting for many users.” “Every plan includes unlimited API calls and unlimited posts,” and its MCP server has 33 tools for posts, analytics, comments and DMs. On tokens, it says “All social networks keys are stored in a secure secret manager vault.”

Price: Premium is $149 a month for 1 profile, Launch is $299 for up to 10, and Business is $599 for 30, with tiered pricing above that.

Watch for: it’s the most expensive place to start here, and “Premium, Business, and Enterprise are billed at signup (no free trial)”; only Launch has a trial, for 28 days. Its MCP docs say “Working with profiles and sub-profiles requires a Business plan (or Enterprise).” And personal connectors in Claude’s apps can’t reach that server, because it needs a header they can’t send. Claude Code can.

Upload-Post

Best for: wide reach at a low price.

Upload-Post has “unlimited uploads to all 22 networks” on every paid plan, a built-in FFmpeg API for video edits, and an MCP server with 50 tools, open source under MIT, that “works with any Upload-Post plan, including the free tier.” Each profile holds one account per network, and white label starts at Professional.

Price: Free gives “10 uploads a month, 2 profiles and full API access.” Basic is $24 a month, or $16 billed yearly, for 5 profiles; Professional is $50, or $33, for 25; Advanced is $147, or $118, for 75; and Business is $438, or $350, for 225.

Watch for: “TikTok is not included on Free.” Daily caps are per social account: 50 Instagram posts, 15 TikTok and 30 YouTube in a rolling 24 hours. Links in X posts are an add-on, at $19 a month. And “Upload-Post handles the OAuth exchange and token storage,” without saying on that page how the tokens are stored.

Blotato

Best for: creators and agencies who want AI-made videos and images, and DM automations, beside the API.

Blotato publishes to nine platforms, and “Every paid plan includes the API and MCP, with no separate API tier.” It’s built for no-code tools as well as code, with n8n and Make nodes. “You log in once per network and Blotato holds the authentication.”

Price: Starter is $29 a month for 20 accounts and 1,250 AI credits, Creator is $97 for 40 accounts and 5,000 credits, and Agency is $499 for 100 accounts and 28,000 credits.

Watch for: there’s no free way to try the API: “API and MCP access is not included in the free trial,” and “Generating a key during a trial ends the trial and starts billing.” New accounts must wait: “Your TikTok account must be warmed up for at least 4 weeks before connecting it,” and “Starter permits 3 distinct TikTok posting destinations per rolling 24 hours.”

Buffer

Best for: a few accounts, with a scheduling app your team can also use.

Buffer’s API is “available on every Buffer plan, including the Free plan,” and creates posts on 11 networks, TikTok, Instagram and YouTube among them. It’s a scheduling app first, with the API beside it, which suits teams that also want a calendar.

Price: Free connects up to 3 channels, with “10 scheduled posts per channel - refill anytime.” Essentials is $5 a channel a month and Team is $10.

Watch for: “the Buffer API doesn’t accept a file upload - there’s no upload endpoint,” so you host every video at a public URL, and its request limits on Free are 150 in 15 minutes and 600 in 24 hours. The help center adds: “You can’t supply your own thumbnail image for a video post.”

Postiz

Best for: running it on your own server, with your tokens and data there too.

Postiz is open source under AGPL-3.0, publishes to “34 social platforms from one calendar,” and has an API, a command line and an MCP server. Its README says the two versions “provide the same core Postiz product and features,” and that on your own server “data never leaves your environment.”

Price: Self-hosting is “Free forever (AGPL-3.0); you pay only for your own infra.” The cloud is $29 a month, or $23 billed yearly, for 5 channels; $39, or $31, for 10; $49, or $39, for 30; and $99, or $79, for 100.

Watch for: “You create your own developer apps on each platform and go through their approval (Meta, YouTube, TikTok can take weeks).” You run “the app plus Postgres, Redis and Temporal,” and “Self-hosting is a secondary option; the hosted platform is where the agent features ship first.”

Zernio

Best for: paying per account, and products that also need DMs, ads or messaging.

Zernio, formerly Late, lists 12 platforms under Social Posting, among 38 across messaging, phone, ads and more, with “Every feature included, no plans, no seats.” Its MCP server is hosted, “so there is nothing to install.” Its privacy policy says “OAuth tokens and stored messages are encrypted at rest.”

Price: “2 accounts free to start, no credit card.” Accounts 3 to 10 cost $6 each a month, 11 to 100 cost $3 and 101 up cost $1, so 10 accounts cost $48 and 100 cost $318.

Watch for: through the MCP server, “An AI client cannot read files on your computer, so media reaches the server through a browser upload,” a step a person has to do, and “The link expires 30 minutes after it is generated.” Other metered services bill on top of accounts, including messaging past its free allowance.

Outstand

Best for: high post volumes and products that resell posting.

Outstand calls itself “The unified social media API for AI agents and the products around them.” It reaches 12 networks, with an MCP server and 28 tools. “Token refreshes? Our problem now.”

Price: Pay as you go is $19 a month with 3,000 posts, then $0.007 a post up to 10,000 and $0.005 after that. Business is $129 with 50,000 posts.

Watch for: “Managed Keys cover 8 of the 12 networks,” so X, Google Business Profile, Vimeo and Reddit need an app of your own. “The furthest you can schedule is 30 days into the future,” and “Uploaded files live in storage for 60 days.”

Post for Me

Best for: low volumes across many accounts, inside your own product.

Post for Me is a posting API for nine platforms. “We handle OAuth, token refresh, media processing, and platform-specific quirks,” and you can use its developer credentials, or your own so your users see your app’s name. It says “Every commit, every pull request, every roadmap decision is public on GitHub.”

Price: $10 a month for “Up to 1,000 successful posts per month,” with unlimited social accounts and team members.

Watch for: “you must run the MCP server locally,” and its code runs in a sandbox “restricted from web or filesystem access.” That suits building an integration more than asking an agent to post a file from your disk.

The platforms’ own APIs

Best for: one or two networks, with no third party holding your tokens. They’re free, and an agent can write the script.

• YouTube said on November 2, 2026 that uploads from unverified API projects “are no longer restricted to private viewing mode.” Uploads have a quota of “100 calls per day.”
• TikTok requires an audit: “All content posted by unaudited clients will be restricted to private viewing mode.”
• Instagram works with professional accounts, and unless you open a resumable upload session for a video, “the media must be hosted on a publicly accessible server at the time of the attempt.”

Watch for: the rest is what these eight companies sell: token refreshes, media rules and each platform’s changes, one integration at a time.

Enjoy, which isn’t an API

Best for: people whose only reason to want an API was to have their own agent post their own videos.

Enjoy is a desktop app for Mac, Windows and Linux that runs Claude Code, Codex, Grok Build, Antigravity, Muse Code, and local models through OpenCode, on the plans you already have. Connect your YouTube channel, and an agent drafts a post of a video in your project. “Nothing goes to YouTube until you check the draft and select Post. Enjoy then uploads the video from your computer.” The login is “saved only on this computer,” and it doesn’t reach Enjoy’s servers.

Price: Enjoy is one monthly subscription, and the first seven days are free, with a card to start. It includes your phone and any browser and your other computers, and each teammate you invite needs a subscription of their own. See pricing.

Watch for: there’s no API to build on, and “Agents can’t post on their own. Every post waits on its card for you,” so it can’t run unattended or post for your customers. The released app posts only to YouTube: we’ve built TikTok and Instagram Reels, and they aren’t in it yet. When they arrive, their sign-ins, and TikTok’s daily token renewals, will pass through Enjoy’s server, because TikTok and Meta keep an app’s secret off the desktop. The server is built not to store or log them, and the login stays on your computer. It isn’t open source, and it’s a monthly subscription on top of your AI plans once the free week ends.

Why who holds the tokens matters

The roundups we read skip this, and it’s worth a look before you connect a brand’s accounts. A hosted API holds the access tokens that let it post for you, so a breach there can reach your accounts. In October 2013, attackers got into Buffer’s database through its hosting provider and were able to “steal some of our Facebook and Twitter access tokens from our users,” then sent spam from those accounts. They didn’t get passwords, and Buffer then “added encryption of OAuth access tokens.”

That was 13 years ago, and holding the tokens is also what lets these services post while your computer is off, which is why you’d pay for one. Self-hosting or using a platform’s own API keeps them with you, and leaves you responsible for keeping them safe. Ask a vendor how it stores tokens, how fast you can revoke them, and whether it publishes a security report.

When to stay with what you have

If your current API does what you need, none of this is a reason to move. An integration that already handles each platform’s errors is worth more than a lower price. If you chose Buffer for the team tools around the API, compare those before you compare prices.

Move when your bill grows faster than your use, when you need a network or a TikTok cap your plan doesn’t cover, or when a client asks who holds their tokens and you don’t like the answer.

How we compared

We read each maker’s pricing, docs and MCP pages on November 3, 2026, and every one is linked below. We quote their own words for the limits, and where a page doesn’t say how a service stores tokens, we say only who holds them. Network counts are the makers’ own: Ayrshare’s pricing page says 14 and its docs compare 13. We didn’t publish test posts through these APIs, so we say nothing about how reliable they are, and reliability should weigh as much as anything here. What we say about Enjoy comes from its help pages and code. Most comparison pages in this category are written by a vendor, as this one is. Prices change often, so we recheck this guide against its sources at least once a month, and the date at the foot of the page says when we last did.
