PostEverywhere gives you one consistent interface for all 11, so you can [post everywhere at once](https://posteverywhere.ai/cross-posting) without wiring up the Meta Graph API, TikTok Content Posting API, and YouTube Data API separately. Full reference lives in the [developer docs](https://posteverywhere.ai/developers). A single REST endpoint. Publish to any of 11 networks through one Bearer-token API. One request shape, one set of docs, every platform covered.Official platform APIs. Every post goes out through the platform's sanctioned API, not browser automation. Compliant, reliable, and account-safe.Typed SDK and MCP server. Install @posteverywhere/sdk for full TypeScript types, or connect any AI agent through the hosted MCP server. ## More than posting Schedule, generate, and measure from one API The same API that publishes also schedules, creates content, and reports results. Generate captions with the [AI content generator](https://posteverywhere.ai/ai-content-generator), produce visuals with the [AI image generator](https://posteverywhere.ai/ai-image-generator), and pull cross-platform numbers from [analytics](https://posteverywhere.ai/social-media-analytics), all through code. Schedule and publish. Queue posts for any time or publish instantly. The API handles per-platform formatting, media upload, and optimal-time scheduling for you.Generate captions and images. Call the API to produce platform-tailored captions and on-brand images from a prompt, then publish them in the same flow.Read analytics and account health. Fetch engagement, reach, follower growth, and per-account health across every connected platform with a single request. ## Built for builders Ship in an afternoon, not a quarter Most of the work in a social integration is not posting, it is the plumbing: OAuth, token refresh, rate limits, retries, and media formatting for every network. PostEverywhere handles all of it so you can [build an agent](https://posteverywhere.ai/build-an-ai-social-media-agent-with-posteverywhere) or product feature in hours. Read the [social media scheduling API guide](https://posteverywhere.ai/blog/social-media-scheduling-api-guide) to see it end to end. No per-platform OAuth maze. Connect accounts once. The API manages tokens, refresh, and re-authentication across every platform on your behalf.Rate limits and retries handled. Built-in rate-limit handling and automatic retries mean one call reaches every network reliably, even under load.Webhooks for delivery status. Subscribe to webhooks for publish success, failures, and account events instead of polling for results. ## Full capability set What you can build on the social media API One Bearer token unlocks publishing, scheduling, media, AI generation, analytics, and webhooks across 11 platforms. Everything the dashboard does is available through the API. One-call publishing Send a single request and your post goes out to Instagram, TikTok, LinkedIn, Facebook, YouTube, X, Threads, Pinterest, Bluesky, Discord, and Telegram through their official APIs.Scheduling and queues Schedule posts for any future time, build evergreen queues, and let the API publish at optimal times per platform. No cron jobs to maintain.Media upload and resizing Upload images and video once. The API resizes and reformats each asset to meet every platform's aspect ratio and codec requirements automatically.AI caption and image generation Generate platform-tailored captions and on-brand images from a prompt, all callable from the same API you publish with.Analytics and reporting Pull engagement, reach, impressions, and follower growth across all 11 platforms, plus per-account health, in a single call.Webhooks, campaigns, and bulk Subscribe to delivery webhooks, group posts into campaigns, and create hundreds of posts in one bulk request.Why teams build on the PostEverywhere API ## One API instead of eleven, maintained for you Wiring up social platforms yourself means a different integration for [Instagram](https://posteverywhere.ai/blog/schedule-instagram-posts-api), [TikTok](https://posteverywhere.ai/blog/post-to-tiktok-api), [LinkedIn](https://posteverywhere.ai/blog/schedule-linkedin-posts-api), [YouTube](https://posteverywhere.ai/blog/post-to-youtube-api), [Facebook](https://posteverywhere.ai/blog/post-to-facebook-api), [X](https://posteverywhere.ai/blog/schedule-x-twitter-posts-api), and [Threads](https://posteverywhere.ai/blog/post-to-threads-api), each with its own auth, review process, and rate limits. PostEverywhere replaces all of it with one integration, and our roundup of the [best social media APIs](https://posteverywhere.ai/blog/best-social-media-apis) explains how the options compare. Already on another provider? Our guides on [migrating from the Buffer API](https://posteverywhere.ai/blog/migrate-from-buffer-api-to-posteverywhere) and the [PostEverywhere API vs the Hootsuite API](https://posteverywhere.ai/blog/posteverywhere-api-vs-hootsuite-api) walk through the move. For a plain-English overview, see [how to automate social media posting with an API](https://posteverywhere.ai/blog/automate-social-media-posting-api). The API is also the fastest way to give software agency over your channels. Connect an [AI agent](https://posteverywhere.ai/agents) through the MCP server, or use the REST API and SDK to [build a social media agent](https://posteverywhere.ai/blog/build-social-media-agent-api) that drafts, schedules, and publishes on its own. Schedule [Pinterest pins by API](https://posteverywhere.ai/blog/schedule-pinterest-pins-api) alongside every other network in the same queue. Because the API drives the same engine as the rest of the product, you also get [cross-posting](https://posteverywhere.ai/cross-posting), [multi-account management](https://posteverywhere.ai/multi-account-management), and [automation](https://posteverywhere.ai/social-media-automation) without extra work. When you are ready, the [developer docs](https://posteverywhere.ai/developers) have the full endpoint reference, SDK, and webhook setup.

It is a single REST API that lets your application schedule, publish, generate, and measure social media content across 11 platforms. Instead of integrating Instagram, TikTok, LinkedIn, YouTube, and the rest one at a time, you connect once and call one consistent endpoint for all of them. ### Which platforms does the social media API support? Instagram, TikTok, LinkedIn, YouTube, Facebook, X (Twitter), Threads, Pinterest, Bluesky, Discord, and Telegram. Every post is published through the platform's official API, so your accounts stay compliant and safe. ### Is there an SDK? Yes. Install @posteverywhere/sdk for a fully typed Node client with promises and inline documentation. You can also call the REST API directly with a single Bearer token from any language. ### Is there a command-line tool? Yes. Install @posteverywhere/cli with npm install -g @posteverywhere/cli to post and schedule across all 11 platforms from your terminal. Run posteverywhere login once, connect your accounts, and publish. Every command also supports --json output, so the same CLI works as a tool for AI agents like Claude and Cursor. ### Can AI agents use the API? Yes. PostEverywhere ships a hosted MCP (Model Context Protocol) server, so agents like Claude, ChatGPT, Cursor, and Codex can schedule posts, generate media, and read analytics in plain language. Drop the MCP URL in and approve, with no install required. ### How is this different from using each platform's API directly? Each platform has its own API, OAuth flow, token refresh cycle, rate limits, and media rules. Building and maintaining all of them is weeks of work that keeps breaking as platforms change. PostEverywhere gives you one integration that handles OAuth, token refresh, rate limiting, retries, and per-platform formatting behind a single consistent interface. ### What are the rate limits? Every plan includes generous limits of 60 requests per minute and 1,000 per hour per API key, with built-in retry and rate-limit handling so a single call reaches every network reliably. ### How much does the social media API cost? API access is included on every plan, starting at $29/mo on Starter. There is no separate API fee, and all plans include a 7-day free trial. See the pricing page for connected-account and AI-credit limits per plan. ### Does it use official platform APIs or browser automation? Official platform APIs only, including the Meta Graph API, TikTok Content Posting API, and YouTube Data API. There is no fragile browser automation or unofficial scraping, which means reliable delivery and accounts that stay in good standing. ## Related Features & Resources Explore related features and guides to get the most out of PostEverywhere.
