BulkPublish API

The free social media API built for automation, AI agents, and LLMs.

Programmatically publish to 11 platforms from a single API call. Built for developers, AI agents, LLMs, and agentic workflows that need reliable social media automation without browser sessions or manual interaction.

from bulkpublish import BulkPublish

bp = BulkPublish("bp_your_key_here")
bp.posts.create(
    content="Launching our new product today!",
    channels=[{"channelId": 1, "platform": "x"}, {"channelId": 2, "platform": "linkedin"}],
    status="scheduled",
    scheduled_at="2026-04-10T09:00:00Z",
)

Why BulkPublish?

Most social media tools are built for humans clicking buttons. BulkPublish is built for code — whether that code is written by a developer, an AI agent, an LLM with tool use, or an autonomous workflow.

• Headless by design — No browser, no UI, no OAuth pop-ups at runtime. Connect accounts once in the dashboard, then automate everything via API.
• AI-native — MCP server for Claude, tool definitions for GPT and LangChain, structured JSON responses that LLMs parse reliably.
• Agentic-ready — Deterministic API with clear error codes. AI agents can create posts, check status, retry failures, and read analytics autonomously.
• 11 platforms, one endpoint — Facebook, Instagram, X/Twitter, TikTok, YouTube, Threads, Bluesky, Pinterest, Google Business Profile, LinkedIn, Mastodon.

Use Cases

• AI social media managers — Let Claude, GPT, or custom agents schedule and publish posts autonomously
• Content pipelines — RSS-to-social, blog-to-social, newsletter-to-social automation
• Bulk scheduling — Upload a CSV or feed a content calendar and schedule weeks of posts programmatically
• Cross-platform syndication — Publish once to all platforms with per-platform content optimization
• Analytics dashboards — Pull engagement data into your own tools, spreadsheets, or AI analysis
• Zapier/n8n/Make alternatives — Direct API access without middleware, lower latency, more control
• LLM-powered content creation — Generate content with AI, publish it with BulkPublish, track performance, iterate

Quick Start

1. Sign up

Create a free account at app.bulkpublish.com.

2. Get your API key

Go to Settings > Developer in the dashboard and create an API key. Keys start with bp_ and are shown only once — save it securely.

3. Connect platforms

Connect your social accounts in the dashboard under Channels. The API uses your connected channels to publish.

4. Install an SDK

Python

pip install bulkpublish

Node.js

npm install bulkpublish

Homebrew (macOS/Linux)

brew tap azeemkafridi/bulkpublish && brew install bulkpublish

Or call the REST API directly with curl, fetch, requests, or any HTTP client.

5. Make your first API call

curl -X POST https://app.bulkpublish.com/api/posts \
  -H "Authorization: Bearer bp_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "content": "Hello from the BulkPublish API!",
    "channels": [{"channelId": 1, "platform": "linkedin"}],
    "status": "draft"
  }'

AI Agent Integration

MCP Server (Claude, Cursor, Windsurf, Claude Code)

BulkPublish ships an MCP server so AI assistants can manage your social media directly:

{
  "mcpServers": {
    "bulkpublish": {
      "command": "npx",
      "args": ["-y", "@bulkpublish/mcp-server"],
      "env": {
        "BULKPUBLISH_API_KEY": "bp_your_key_here"
      }
    }
  }
}

12 tools available: create_post, list_channels, upload_media, get_analytics, and more. See mcp-server/README.md.

LLM Tool Use / Function Calling

Ready-made tool definitions for autonomous AI agents:

• Claude tool_use example — Anthropic SDK with tool definitions for scheduling posts
• OpenAI function calling example — GPT-4 with functions for post management
• LangChain tool example — LangChain agent with BulkPublish tools

All examples are complete, runnable scripts with error handling.

Code Examples

Create a Post

Python	Node.js
from bulkpublish import BulkPublish bp = BulkPublish("bp_your_key_here") post = bp.posts.create( content="Check out our latest update!", channels=[ {"channelId": 1, "platform": "facebook"}, {"channelId": 2, "platform": "x"}, {"channelId": 3, "platform": "linkedin"}, ], status="draft", )	import { BulkPublish } from 'bulkpublish'; const bp = new BulkPublish({ apiKey: 'bp_your_key_here' }); const post = await bp.posts.create({ content: 'Check out our latest update!', channels: [ { channelId: 1, platform: 'facebook' }, { channelId: 2, platform: 'x' }, { channelId: 3, platform: 'linkedin' }, ], status: 'draft', });

Schedule a Post

post = bp.posts.create(
    content="This will go out tomorrow morning.",
    channels=[{"channelId": 1, "platform": "instagram"}],
    status="scheduled",
    scheduled_at="2026-04-10T09:00:00Z",
    timezone="America/New_York",
)

Upload Media and Publish

media = bp.media.upload("./product-photo.jpg")

post = bp.posts.create(
    content="Our newest product is here.",
    channels=[{"channelId": 1, "platform": "instagram"}],
    media_files=[media["file"]["id"]],
    status="scheduled",
    scheduled_at="2026-04-10T12:00:00Z",
)

Automation Example: Bulk Schedule from CSV

import csv
from bulkpublish import BulkPublish

bp = BulkPublish("bp_your_key_here")
channels = bp.channels.list()["channels"]

with open("content-calendar.csv") as f:
    for row in csv.DictReader(f):
        bp.posts.create(
            content=row["content"],
            channels=[{"channelId": ch["id"], "platform": ch["platform"]} for ch in channels],
            status="scheduled",
            scheduled_at=row["scheduled_at"],
            timezone="America/New_York",
        )
