The Best Social Media APIs for Developers in 2026

Updated September 2026 · bundle.social, Buffer API, Postiz and Unipile added · MCP, SDK and engagement columns

Short answer: for most developers we recommend Upload-Post: 22 platforms, a free plan with API access, unlimited uploads from $24/month, and comments, DMs and analytics on the same key. Ayrshare fits teams that want the longest-running vendor, Zernio fits per-account billing, and Postiz or Mixpost fit teams that must self-host.

Disclosure: Upload-Post publishes this comparison. Every competitor value was read on the vendor’s own pricing page, homepage or docs on 29 September 2026, and each entry says where a competitor is the better choice.

What we compared

Six things developers check before they wire the first endpoint.

Platforms

Networks the API can publish to, as the vendor lists them. Read-only or messaging-only integrations are noted separately.

MCP / agent-ready

Whether an MCP server lets Claude, ChatGPT, Cursor or your own agent call the API without glue code.

SDKs

Official client libraries named on the vendor’s site or docs. An OpenAPI spec alone is listed as such.

Comments, DMs, analytics

Whether the API goes beyond posting. A dash means the vendor does not list it, not that it is impossible.

Entry price

The cheapest plan that includes API access, at list price, monthly billing unless stated.

Free tier

A plan you can keep using without paying. Time-limited trials are listed as trials.

Which social media API should you choose?

One verdict per API, with the pros and cons that matter when you integrate it.

1. Upload-Post

Developers, SaaS products and agencies

$24/mo ($16/mo annual), unlimited uploads · 22 platforms · MCP: Yes, hosted remote server

Upload-Post is our own product, so weigh this entry accordingly. It is a hosted REST API that publishes video, photos, documents and text to 22 platforms with one request, and the same API key covers scheduling, comments on eight networks, Instagram DMs and comment-to-DM automations, and analytics on eleven networks. A hosted MCP server exposes the same tools to Claude, ChatGPT and Cursor, and there are official Python and Node SDKs plus n8n and Make nodes. Pricing is flat per plan, with unlimited uploads on every paid plan and whitelabel account linking from the $50/month Professional plan.

Pros
  • Flat pricing with unlimited uploads from $24/mo
  • Free plan with full API access, no card
  • Comments, DMs and analytics on the same API key
  • Hosted MCP server, Python and Node SDKs, n8n and Make
Keep in mind
  • Publishing and engagement API, not an AI content generator
  • Hosted service: teams that must run everything on their own servers should look at Postiz or Mixpost

2. Ayrshare

Funded teams that want the longest-running vendor

$149/mo (Premium, 1 profile) · 14 platforms · MCP: Yes

Ayrshare is the most established social media API and it shows: thorough documentation, Python and Node packages, webhooks, and a messaging API that covers Instagram, Facebook, WhatsApp and X. Analytics and comment moderation are included on every plan. The trade-off is the entry price. Premium is $149/month for a single profile, Launch is $299/month and Business starts at $599/month, so it suits companies where the vendor track record matters more than the bill.

Pros
  • Mature docs, SDKs and webhooks
  • Comments, DMs (including WhatsApp) and analytics
  • Unlimited team members from Launch up
Cons
  • Entry plan is $149/mo for one profile
  • No free plan; the trial is on the $299/mo Launch plan

3. Zernio

Products that bill per connected account, or need messaging and ads too

$6 per account/mo (accounts 3 to 10) · 16 social and messaging networks, plus ad networks platforms · MCP: Yes (mcp.zernio.com)

Zernio (formerly Late) prices by connected account with every feature included: the first two accounts are free, then $6 per account per month up to 10, $3 up to 100 and $1 beyond that. Its API is broad, covering posting, comments, DMs across several networks, analytics, webhooks and ad platforms, with an MCP server at mcp.zernio.com. The per-account model is cheap at the very small and very large end; in the middle, where most agencies sit, a flat plan often costs less.

Pros
  • Two accounts free with no time limit
  • Comments, DMs, analytics and ads endpoints
  • Simple graduated per-account pricing
Cons
  • Cost grows with every connected account
  • Ad-network features add to the surface you have to learn

4. Outstand

AI-agent products with low or spiky posting volume

$19/mo with 3,000 posts, then $0.007/post · 12 platforms · MCP: Yes, 28 tools

Outstand is usage-metered: $19/month includes 3,000 posts, then $0.007 per post up to 10,000 and $0.005 above that, with a $129/month Business plan for 50,000 posts. Its MCP server is one of the largest on this list, with 28 tools that cover posting, scheduling, replies, media and analytics. Its managed keys cover 8 of its 12 networks, so on the other four (X, Google Business Profile, Vimeo and Reddit) you register your own developer app.

Pros
  • Cheap at low volume, 3,000 posts included
  • 28-tool MCP server
  • Covers Vimeo and Google Business Profile
Cons
  • Your own developer app needed on 4 of 12 networks
  • Metered cost keeps rising with volume

5. Post for Me

Low-volume apps that want the cheapest entry and many SDKs

$10/mo for up to 1,000 posts · 9 platforms · MCP: Yes

Post for Me, by Day Moon Development, is the cheapest hosted entry point we found: $10/month for up to 1,000 successful posts, with unlimited accounts, API keys and team members, and custom plans above that. It has the widest SDK spread on this list (JavaScript/TypeScript, Python, Ruby and Go), an MCP server, feed reading and post analytics, and you can bring your own platform credentials so users see your app on the OAuth screen. Coverage is the nine largest networks.

Pros
  • $10/mo entry price
  • SDKs in four languages
  • Bring-your-own credentials for branded OAuth
  • Open source on GitHub
Cons
  • Nine networks
  • Comment and DM endpoints not listed on its site

6. bundle.social

Teams posting at high volume across many accounts

$100/mo per organization (Pro) · 15 platforms · MCP: Yes

bundle.social has a real free plan (20 posts and 50 comments a month on 3 accounts) and then jumps to $100/month per organization for 10,000 posts and unlimited accounts, or $400/month for 100,000 posts. The API covers comments and analytics, DMs are in beta, and there is an official MCP server plus a typed SDK and CLI. X is billed on top of every plan at $0.015 per post and $0.20 per post with a link.

Pros
  • Free plan with API access
  • Unlimited accounts on paid plans
  • Comments API and an MCP server
Cons
  • Big step from free to $100/mo
  • X posts billed per post on every plan
  • DMs still in beta

7. Buffer API

Buffer users who want to script their own queue

$5 per channel/mo (Essentials) · 12 platforms · MCP: Yes

Buffer now offers a public API on every plan: the free plan gets 1 API key and 3,000 requests a month, Essentials ($5 per channel) 3 keys and 7,500 requests, and Team ($10 per channel) 5 keys and 15,000 requests. It creates drafts, scheduled, image, video and threaded posts (Buffer says analytics and community endpoints are still to come), and there is an MCP integration for Claude, ChatGPT and Cursor. It is built around your own Buffer channels, so it fits automating a Buffer workspace better than powering a multi-customer product.

Pros
  • API on the free plan
  • Familiar scheduler behind it
  • MCP integration for Claude, ChatGPT and Cursor
Cons
  • Request quotas per plan
  • Per-channel pricing grows with accounts
  • Built for your own channels rather than your customers’

8. Postiz

Teams that want open source or self-hosting

$29/mo (Standard, 5 channels) · ~30 platforms · MCP: Yes, all plans

Postiz is an open-source scheduler you can self-host for free or buy as a cloud plan from $29/month for 5 channels up to $99/month for 100. It supports the widest list of networks here, around 30, and ships a public API, a Node.js SDK, an n8n node and an MCP server on every plan. The public API is rate-limited to 90 create-post requests an hour on self-hosted instances (100 on cloud), which is fine for a team calendar and tight for a product posting on behalf of many users.

Pros
  • Open source, self-host for free
  • Around 30 networks
  • MCP and API on every plan
Cons
  • Create-post endpoint limited to about 90-100 requests an hour
  • Self-hosting means registering your own platform apps

9. Blotato

Creators who want AI generation and posting in one bill

$29/mo (Starter) · 9 platforms · MCP: Yes

Blotato bundles AI writing, image, video and voice generation with posting to nine networks through an API and MCP server. Plans run $29, $97 and $499 a month and are sized by AI credits, connected accounts and "active contacts" for DMs and comment replies (1,000 a month on Starter). The API is excluded from the 7-day trial, so you pay before you can test the integration.

Pros
  • AI content generation built in
  • MCP server, n8n and Make nodes
  • Comment replies and DMs included by contact volume
Cons
  • API not available during the trial
  • Credit and contact meters make costs harder to predict

10. Post Bridge

Solo builders who want a simple scheduler with an API

$39/mo (Marketer, 15 accounts) · 10 platforms · MCP: Yes

Post Bridge is a lean scheduler from an independent developer. The Marketer plan is $39/month for 15 connected accounts with the API and MCP included, and Operator is $99/month for 99 accounts, then $1 per extra account. It covers ten networks including Google Business. It is a posting tool first, so check its docs before counting on engagement endpoints.

Pros
  • API and MCP included in the base plan
  • Low per-account cost on Operator
  • Simple product
Cons
  • No free plan
  • Engagement and analytics endpoints not listed on its pricing page

11. Mixpost

Teams that want to own the install and skip subscriptions

$299 one-time (Pro) · 11+ (Pro) platforms · MCP: Yes (Pro, Enterprise)

Mixpost is self-hosted software you buy once: Pro is $299 and Enterprise $1,199, both with unlimited accounts and team members, an API, an MCP server and a year of updates. The free Lite edition covers Facebook Pages, X and Mastodon. As with any self-hosted tool, you register and maintain your own developer apps with Meta, TikTok, Google and the rest, including their app reviews.

Pros
  • One-time payment
  • Unlimited accounts and users
  • You keep the data on your server
Cons
  • Your own developer apps and app reviews per network
  • You run the server and updates; new versions after year one need renewal

12. Unipile

Messaging and outreach products, especially on LinkedIn

€49/mo for up to 10 accounts · LinkedIn, WhatsApp, Instagram, Telegram, plus email and calendar platforms · MCP: —

Unipile is a different kind of API: it unifies messaging (LinkedIn, WhatsApp, Instagram and Telegram) with email and calendars, and adds posting and commenting on LinkedIn and Instagram. It costs €49/month for up to 10 accounts, then €5 per account down to €3 at volume, with no per-message fees. Pick it when the product is an inbox or outreach tool; for publishing video across many networks it is not the right fit.

Pros
  • Messaging across LinkedIn, WhatsApp, Instagram and Telegram
  • Email and calendar in the same API
  • No per-message fees
Cons
  • Publishing limited to LinkedIn and Instagram
  • Not built for multi-network video publishing

What about the native platform APIs?

Integrating each network directly is always an option. This is what each one asks of you before the first public post.

Instagram and Facebook (Meta Graph API)

Free to call, but you need a Meta developer app, App Review for the publishing and messaging permissions, and Business or Creator accounts. Tokens expire and have to be refreshed.

TikTok Content Posting API

Free, but posts from an unaudited app are restricted to private viewing until TikTok audits the app. Comments and analytics live behind separate scopes.

YouTube Data API

Free within daily quotas per Google Cloud project: by default 100 videos.insert calls a day and 10,000 units for everything else. More quota means filing the Quota Extension Form and passing an audit.

LinkedIn APIs

No public price list. Posting as a member is available to verified apps; company page management and analytics sit behind LinkedIn’s partner review.

X API

Pay-per-use since 2026: you buy credits and each request is deducted, $0.015 to create a post and $0.20 for a post with a URL. You also handle OAuth and media upload yourself.

Each of these is one integration. A unified social media API does the app reviews, OAuth and token refresh once for all of them.

Try Upload-Post free, no credit card

Post to 22 platforms, answer comments and DMs, and pull analytics with one API key. 10 free uploads a month, unlimited from $24/month.

Frequently asked questions

What developers ask before picking a social media API.

What is the best social media API for developers in 2026?

For most developers, Upload-Post: 22 platforms, a free plan with API access, unlimited uploads from $24 a month, and comments, DMs and analytics on the same key, with a hosted MCP server and Python and Node SDKs. Ayrshare suits teams that want the longest-running vendor and can pay $149 a month or more, Zernio suits per-account billing, and Postiz or Mixpost suit teams that must self-host. This page is published by Upload-Post; competitor facts were checked on their own sites on 29 September 2026.

How did you compare these social media APIs?

On six things a developer checks before integrating: how many platforms the API publishes to, whether it has an MCP server for AI agents, which SDKs exist, whether it covers comments, DMs and analytics as well as posting, the entry price for API access, and whether there is a free tier. Every competitor value was read on the vendor’s own pricing page, homepage or docs; where we could not verify something, the table shows a dash.

What is the cheapest social media API?

Among hosted APIs, Post for Me starts at $10 a month for up to 1,000 posts and Outstand at $19 a month with 3,000 posts included. Zernio is free for 2 connected accounts, Buffer includes 3,000 API requests a month on its free plan, and Upload-Post’s free plan has 10 uploads a month with full API access. For unlimited uploads, Upload-Post starts at $24 a month ($16 billed annually).

Which social media APIs have an MCP server?

As of September 2026: Upload-Post, Ayrshare, Zernio, Outstand, Post for Me, bundle.social, Buffer, Postiz, Blotato, Post Bridge and Mixpost Pro. They differ in scope. Some MCP servers only post, while Upload-Post’s also exposes comments, Instagram DMs, analytics and scheduling, and runs as a hosted remote server you add by URL in Claude, ChatGPT or Cursor.

Which social media APIs support comments, DMs and analytics?

Upload-Post, Ayrshare, Zernio, bundle.social (DMs in beta) and Blotato cover all three. Upload-Post’s Comments endpoints work on Instagram, Facebook, YouTube, LinkedIn, TikTok, X, Threads and Bluesky, its DM endpoints cover Instagram including comment-to-DM automations, and analytics cover eleven networks. Outstand, Post for Me, Buffer and Postiz list analytics; Unipile focuses on messaging.

Should I use a unified API or each platform’s native API?

Native APIs are free or pay-per-use to call, but each needs its own developer app, OAuth flow, token refresh and, on Meta, TikTok, YouTube and LinkedIn, an app review or audit before you can post publicly. A unified API does that work once for every network. Go native when you need a platform feature no aggregator exposes, or when you only ever post to one network.

Ayrshare vs Upload-Post: which should I pick?

Both cover posting, scheduling, comments, DMs, analytics and whitelabel. Ayrshare starts at $149 a month for one profile, has no free plan and adds WhatsApp messaging. Upload-Post starts free, charges $24 a month for unlimited uploads, covers 22 platforms and includes whitelabel from $50 a month. See the Upload-Post vs Ayrshare page for the full table.
