Which social media API should you choose?

One honest verdict per tool, with the pros and cons that actually matter to buyers.

1. Upload-Post

Most developers, indie SaaS and agencies

Free plan · paid from $24/mo ($16/mo annual)

Upload-Post is our own product, so read this with that in mind. The numbers are public, though. It's a posting-first REST API: one multipart POST publishes a video, photo set or text post to TikTok, Instagram, YouTube, LinkedIn, Facebook, X, Threads, Pinterest, Reddit, Bluesky, Discord and Telegram, with scheduling, analytics, an FFmpeg processing API and whitelabel account-linking for SaaS. The free tier is a real plan (10 uploads/month forever), and every paid plan has unlimited posts.

Pros
  • Unlimited posts on every paid plan ($24/mo)
  • Real free tier with full API access
  • Whitelabel from $50/mo (vs $149/mo at Ayrshare)
  • Official n8n node, Make module, MCP server
Cons
  • No self-hosted option
  • Younger product than Ayrshare or Buffer
  • TikTok posting requires a paid plan

2. Ayrshare

Funded startups and enterprises that want the most mature API

From $149/mo (Premium) · $299/mo Launch · $599/mo Business

Ayrshare is the most established social media API and it deserves credit for that: excellent documentation, SDKs, webhooks, and enterprise features like SSO and dedicated support. The trade-offs are price and quotas. The cheapest plan is $149/month for a single user profile, and maximum posting limits require a $300/month Max Pack add-on. If budget isn't a constraint and you want the longest track record, Ayrshare is a safe choice.

Pros
  • Most mature docs and SDK ecosystem
  • Enterprise features (SSO, DAM integrations)
  • Unlimited team members on all plans
Cons
  • Cheapest plan is $149/mo
  • Max posting limits cost +$300/mo (Max Pack)
  • No free tier; trial requires the $299/mo plan

3. Blotato

AI-content creators who want generation + posting in one tool

$29/mo Starter · $97/mo Creator · $499/mo Agency

Blotato bundles AI content creation (images, videos, carousels from templates) with posting, and its MCP server is genuinely good: 14 tools that work from Claude, Cursor or Replit without code. The catch for API buyers is that the API is excluded from the 7-day trial, so you can't test it before paying. Usage is also metered through AI credits, which makes cost prediction harder than a flat unlimited plan.

Pros
  • Strong AI generation built in (faceless video, carousels)
  • Polished MCP server for AI agents
  • Good remix/repurposing workflows
Cons
  • API not available during the trial
  • AI-credit metering complicates budgeting
  • No whitelabel, account caps per tier (20/40)

4. Post Bridge

Indie hackers on the smallest possible budget

From $9/mo Starter · $29/mo Creator · $49/mo Pro (API add-on +$5/mo)

Post Bridge is the budget pick: a lean scheduler by an indie developer with a REST API sold as a $5/month add-on on top of plans that start around $9/month. Honestly, for a solo builder posting to a handful of accounts it's hard to beat on price. It's a smaller operation than the rest of this list, though, so expect a leaner feature set (no whitelabel, no analytics API depth) and plan limits on connected accounts below the Pro tier.

Pros
  • Cheapest API entry point (~$14/mo all-in)
  • MCP/AI-agent access on the base plan
  • Simple, no-frills product
Cons
  • Small team / less enterprise assurance
  • No whitelabel or team features
  • Account caps below the Pro plan

5. Mixpost

Teams that want full data ownership and no subscription

Lite: free OSS · Pro: $299 one-time · Enterprise: $1,199 one-time

Mixpost is the best self-hosted option: pay $299 once (Pro) and run it on your own server with unlimited accounts and users, API, MCP and even multi-tenant workspaces. The honest caveat every self-hosted buyer should know: you must create and maintain your own developer apps with each social network (Meta, TikTok, Google...), pass their app reviews, and handle token expiry yourself. That's exactly the work hosted APIs like Upload-Post or Ayrshare do for you.

Pros
  • One-time payment, no monthly fees
  • Unlimited accounts and team members
  • Full data ownership; open-source Lite edition
Cons
  • You must register and maintain your own platform apps + reviews
  • You operate the server, updates and uptime
  • Updates free for 1 year, then renewal for new versions

Full comparison: Upload-Post vs Mixpost

6. Buffer

Humans scheduling manually, not API automation

Free (3 channels) · Essentials $6/channel/mo ($5 annual)

Buffer is a great scheduler for people and a poor choice for programmatic posting: its public developer API has been closed to new applications for years, so you can't build on it today. We include it because many "social media API" searches end up at Buffer. If you want Buffer's simplicity with an actual API, look at Upload-Post, Late/Zernio or Post Bridge instead.

Pros
  • Polished UI, generous free plan for manual use
  • Cheap per-channel pricing at small scale
  • Long, trusted track record
Cons
  • No self-serve public API for new developers
  • Per-channel pricing balloons with many accounts
  • No MCP/AI-agent surface

7. SocialPilot

Small agencies that mostly work in the dashboard

$20/mo Essentials · $40 Standard · $100 Premium · $200 Ultimate

SocialPilot is an agency dashboard first: affordable seats, client approval flows and white-label reports from the $100/month Premium tier. As an API play it falls short: API access is restricted to the custom-priced Enterprise plan, so developers can't self-serve. Choose it if your team lives in a UI and only might need an API later.

Pros
  • Good value dashboard ($20-40/mo tiers)
  • White-label portal for agencies from Premium
  • Bulk scheduling (500 posts) and approval workflows
Cons
  • API only on custom Enterprise plans
  • No free plan
  • Not built for developer automation

8. Late (now Zernio)

Usage-based billing fans scaling account counts

First 2 accounts free · then $6/account/mo (3-10), $3 (11-100), $1 (101+)

Late rebranded to Zernio in 2026 and moved to pure usage-based pricing: every connected account is the billing unit, with graduated rates and all features included. That's elegant for apps whose account counts vary, and genuinely cheap at both the very small end (2 accounts free) and the very large end ($1/account beyond 100). Between those extremes a flat unlimited plan like Upload-Post's $24/month is usually cheaper, and the recent rebrand means docs and links are still settling.

Pros
  • Simple per-account pricing, all features included
  • 2 accounts free with no time limit
  • Messaging (WhatsApp/Telegram/Discord) and ads endpoints too
Cons
  • Per-account cost adds up mid-scale (10 accounts ≈ $48/mo)
  • X/Twitter API costs passed through per request
  • Fresh rebrand, so docs and naming are still moving targets

How did we rank these APIs?

Four criteria, in order: price for equivalent capability, platform coverage, developer experience (docs, SDKs, MCP), and business features (whitelabel, teams).

  • Price: we compared the cheapest plan that includes API access and multi-platform posting, and noted quota add-ons (like Ayrshare's $300/mo Max Pack) that change the real cost.
  • Platforms: counted only officially supported publishing targets, not read-only or analytics-only integrations.
  • Developer experience: REST docs quality, SDKs, no-code modules (n8n, Make, Zapier) and MCP servers for AI agents (a 2026 requirement we weighed heavily).
  • Honesty check: where a competitor wins a use case (Ayrshare for enterprise, Mixpost for self-hosting, Post Bridge on raw price), we say so above.

Frequently asked questions

The questions developers actually ask before picking a social media API.

What is the best social media API in 2026?

For most developers the best social media API in 2026 is Upload-Post: a real free tier, unlimited posts from $24/month, 22 platforms, and whitelabel from $50/month. Ayrshare ($149+/month) is the best pick for enterprises wanting the most mature vendor, and Mixpost ($299 one-time) is the best self-hosted option. This comparison is published by Upload-Post, and every competitor price was verified on public pricing pages in July 2026.

What is the cheapest social media API?

Post Bridge is the cheapest hosted API at roughly $14/month all-in (a ~$9/month Starter plan plus a $5/month API add-on). Late/Zernio is free for up to 2 connected accounts. Upload-Post is the cheapest with unlimited posts: $24/month monthly or $16/month billed annually. Self-hosted Mixpost Pro is $299 one-time but you run the infrastructure and platform app reviews yourself.

Is there a free social media API?

Yes. Upload-Post has a permanent free plan (10 uploads/month, 2 profiles, no credit card) with full REST API access to 9 platforms. Late/Zernio is free for 2 connected accounts. Mixpost Lite is free open-source software, but you must self-host it and register your own developer apps with each social network.

Which social media APIs support MCP and AI agents?

As of July 2026, Upload-Post, Ayrshare, Blotato, Post Bridge, Mixpost (Pro) and Late/Zernio all offer MCP servers so AI agents like Claude can post directly. Blotato ships 14 MCP tools, and Upload-Post additionally publishes Claude Code skills per platform. Buffer and SocialPilot have no MCP or self-serve API surface.

Should I use a unified API or integrate each platform directly?

Direct integration means building and maintaining a separate developer app, OAuth flow and app review with Meta, TikTok, Google, LinkedIn, X and every other network. That's typically weeks of work each, plus ongoing token maintenance. A unified API costs $9-149/month and reduces that to one REST call. Direct integration only wins if you need platform features no aggregator exposes, or at a very large scale where per-seat pricing matters.

Ayrshare vs Upload-Post: which should I pick?

Pick Ayrshare if you're an enterprise that values the longest track record, SSO and dedicated support, and a $149-599/month budget is fine. Pick Upload-Post if you want the same core capability (multi-platform posting, scheduling, analytics, whitelabel) with unlimited posts from $24/month and a free tier to test with.
