Best Social Media Scheduler APIs

If you need software to post to social media, you have two routes. Integrate with each platform’s own API, or integrate once with a social media scheduling API from a tool that has already done that work. The second is cheaper than it looks and the first is far more expensive than it looks.

This page compares the tools and what they cost. Three related questions have their own pages: how to actually schedule a post with an API, queue publishing versus timestamps, and adding scheduling to your own SaaS product.

Why going direct usually goes badly

The APIs themselves are mostly free. Meta does not charge per call for the Instagram Graph API. LinkedIn’s consumer tier costs nothing. What costs you is everything around them.

Meta requires App Review and business verification before your app can touch anyone’s account but your own, and approval commonly runs past a month. YouTube has its own review. TikTok gates direct publishing behind an audit, and until you clear it your posts land as private drafts. LinkedIn is the worst of the set: the consumer tier lets you post to your own feed, and everything past that — company pages, analytics, posting on behalf of clients — sits behind a partner application with no published price and no published timeline.

Then there is the part that never ends. Meta tokens expire roughly every sixty days and need refreshing. Every network has its own media rules, its own rate limits, and its own habit of changing them. You are not building an integration once; you are adopting six of them permanently.

For a team whose product is not social media publishing, that is rarely a sensible use of engineering time. A scheduler’s API is one integration, one auth flow, one thing to keep working.

What to check before you commit

Four things, in roughly this order of how often they cause regret.

Which plan unlocks it. API access is a common upsell, and the tier it sits on moves around. Check the current pricing page rather than trusting any comparison article, this one included.

What it can actually do. Plenty of “APIs” only create drafts, or only cover a subset of networks. If you need to publish Reels, or read analytics back, confirm those specific endpoints exist.

How failures surface. A post can fail hours after you queue it, when the network rejects it. If the API has no webhook and no failure state you can poll, you will find out from a client.

Whether there is an MCP server. Increasingly the question is not whether you can write an integration but whether you need to. More on that below.

Scheduler API comparison at a glance

The short version before the detail. Prices are the entry points we found at the time of writing, so treat them as a starting point and confirm on each vendor’s site.

Tool	Starting price	How it bills	MCP server	Best for
SchedPilot	$21/mo, API included	Flat, by account bundle	Yes	Product features and AI agents
Publer	$5 first account, $4 each after	Per account	No	Small builds on a tight budget
Buffer	Free for 3 channels, then $6/channel	Per channel	No	Prototyping
SocialPilot	$34/mo (annual) for 10 accounts	Bundled accounts and seats	No	Agency-style tools
Metricool	About $20/mo for 5 brands	Per brand	No	Reading analytics back
Sendible	$299/mo for 100 profiles (white-label)	Per profile tier	No	Branded client dashboards
Hootsuite	$99 per user/mo	Per seat	No	Teams already paying for it
Sprout Social	$199 per user/mo (annual)	Per seat	No	Teams already paying for it

1. SchedPilot

SchedPilot is first for two reasons. API access is included on the entry plan at $21 a month rather than reserved for an agency tier, and it is the only tool here that also ships a native MCP server.

That second point is the one worth understanding. A REST API means you write a client, handle auth, describe the endpoints to whatever is calling them, and maintain all of it. An MCP server means an AI assistant connects and discovers the available actions itself, with no integration code at all. If the thing consuming your API is going to be an agent rather than your own backend, you have just skipped the entire build.

Both routes reach the same nine networks: Instagram, TikTok, LinkedIn, YouTube, X, Facebook, Threads, Bluesky and Pinterest. Flat pricing helps here too, since programmatic posting tends to grow account count rather than post volume. Gold covers twenty accounts for $35 and Enterprise a hundred for $79.

2. Publer

The cheapest way to get programmatic posting working, at $5 for the first account and $4 for each one after. Publer is the pick when you are building something small and the per-account cost is the constraint.

It also offers a second route that developers routinely overlook: bulk CSV import, up to 500 rows. If your system already produces a schedule, generating a file is often simpler than writing an API client, and it needs no auth flow at all. Not elegant, extremely fast to ship.

The catch is analytics. The Professional plan has none, so anything you build on it is write-only until you move to Business.

3. Buffer

Buffer has had a public API longer than most of this category has existed, and the free plan covering three channels makes it the obvious place to prototype. You can prove your integration works before paying anyone.

Buffer is also the tool that made the queue model popular, which matters if what you want is a social media queue API rather than one that fires at exact timestamps.

It stops making sense in production at scale, for the same reason it always does: $6 per channel per month means a system managing twenty accounts costs $100 before you have sent a single post. Our head-to-head on automation runs those numbers properly.

4. SocialPilot

Worth a look if what you are building is agency-shaped, because SocialPilot bundles users with accounts rather than charging separately: ten accounts and three seats for $34 a month on annual billing. Bulk scheduling takes 500 posts per CSV, which again is a legitimate integration path.

Check which tier exposes the API before buying, as this is exactly the kind of feature that sits a plan higher than you expect.

5. Metricool

Most integrations are good at pushing posts out and useless at reading results back. Metricool is the inverse, and at around $20 a month for up to five brands it is the cheapest way to pull decent cross-network reporting into your own system, competitor benchmarking included.

A pairing that works well in practice: one tool for publishing, Metricool for measurement. It bills per brand rather than per channel, which suits a single product with many accounts.

6. Sendible

If you are building something client-facing and want your own branding on it, Sendible is the one designed for that. $299 a month covers a hundred profiles with white-label dashboards, which is cheap against the enterprise options and expensive against everything else.

Be clear about what that white-label actually is, though. You get Sendible’s own app wearing your logo, colours and domain, which your clients log into. That is great for an agency reselling a service. It is not the same as scheduling appearing inside your own software, with your own UI, where your users never see a second product. People searching for a white-label solution to add scheduling to their software product usually want the second thing, which we cover in white-label scheduling for SaaS products.

Only sensible if the branded dashboard is the point. If you just need to post, you are paying a large premium for a layer you will not use.

7. Hootsuite and Sprout Social

Both have mature, well-documented APIs and neither is a sensible thing to buy in order to get one. Hootsuite is $99 per user per month and Sprout Social $199 on annual billing, and the capabilities that justify those prices are not the API.

Sprout Social in particular is built around the social inbox, listening and reporting for large teams. Seat-based pricing is the problem for programmatic use: your integration does not need a seat, but the plan is priced as if every user is a person sitting in the app. A 5-person marketing team is already near $1,000 a month before anyone writes a line of code.

If your organisation already pays for one, use what you are entitled to. Otherwise look further down this page, or at our round-ups of Hootsuite alternatives and Sprout Social alternatives, which compare both on features rather than API access. SchedPilot vs Hootsuite is the direct head-to-head.

MCP is changing the question

For a decade, “does it have an API” was the right question because the thing calling it was your own code. That assumption is weakening. Model Context Protocol is an open standard for describing a product’s capabilities to an AI assistant, so the assistant can use them without a bespoke integration. Where an API needs a developer, an MCP server needs a configuration line.

SchedPilot is currently the only tool in this directory shipping one; the others have REST APIs an agent can reach only through a wrapper somebody has to write and maintain. Expect that to change. We cover the landscape in MCP servers for social media, and which schedulers suit agent-driven work in schedulers for AI agents.

Which to pick

A side project or an internal tool

Buffer’s free plan to prototype, then Publer at $5 an account when it goes live. Total cost of finding out: nothing.

A product feature your customers will depend on

SchedPilot, for the API on the entry plan and flat pricing as account count grows. Confirm the failure-reporting behaviour during the trial, because that is what will bite you in production.

Scheduling inside your own SaaS, under your brand

A multi-tenant unified social API, so your customers connect their own accounts without ever seeing another vendor. Not Sendible, which rebrands its own app rather than disappearing into yours. The white-label guide covers all three routes.

An AI assistant doing the posting

SchedPilot’s MCP server, and skip writing an integration at all.

Reporting rather than publishing

Metricool, at about $20 a month, regardless of what you use to publish.

Frequently asked questions

Is there a free social media posting API?

The platforms’ own APIs are free to call, but reaching anyone’s account other than your own requires app review and, on LinkedIn, partner approval. Buffer’s free plan is the cheapest practical way to post programmatically to three channels without any of that.

Which scheduler includes API access on its cheapest plan?

SchedPilot, from $21 a month. Most tools reserve API access for a higher tier, so check the current pricing page before committing to any of them.

Does Sendible have an API?

Sendible’s main draw is its white-label client dashboard rather than developer tooling. If API access is the reason you are buying, confirm the current terms with Sendible directly, and compare against cheaper options above that include an API on their entry plan.

Is Sprout Social worth it just for its API?

No. At $199 per user per month on annual billing you are paying for the inbox, listening and reporting. If the API is all you need, SchedPilot, Publer or Buffer get you there for a fraction of that.

How much does the Instagram API cost?

Meta charges nothing per call. The real cost is App Review, business verification, and maintaining token refresh on a roughly sixty-day cycle. For most teams that is more expensive than paying a scheduler.

Can I schedule to TikTok through an API?

Yes, though direct publishing requires clearing TikTok’s audit first; until then posts arrive as private. You also cannot attach a sound from TikTok’s library programmatically, so audio has to be baked into the file.

Should I build on a scheduler or go direct?

Go direct only if social publishing is your product, or if you need something no scheduler exposes. For everything else, one integration against a scheduler beats six against platforms that each change independently.
