# Add social media posting to your product with one API.

Schedule and publish to 15 channels through one REST API, an OpenAPI spec, SDKs and webhooks. Every plan includes the API, Free included, with no per-call fees.

## Sounds familiar?

- "Each network has its own app review, tokens and limits." Your users connect their accounts in PostBoost. You call one API.
- "A retried request posted twice." Send an Idempotency-Key and a retry never creates a second post.
- "We only find out a post failed when a customer complains." Webhooks tell your code when a post publishes or fails, or when an account needs reconnecting.

## Built for developers

- **One API, 15 channels**: One request format for every network.
- **OpenAPI spec and SDKs**: Generate a client from the spec or use one of ours.
- **Scoped keys**: Give each key only what it needs: read, write, publish, AI or webhooks.
- **Agents too**: The same actions are MCP tools, so your users' AI agents can work with the same posts.

## Features you will use first

- [API and webhooks](https://postboost.co/api-for-developers): Keys, webhooks, retries and guardrails.
- [Agents and MCP](https://postboost.co/features/agents): MCP tools on the same data.
- [Automations](https://postboost.co/features/automations): RSS feeds and recycling rules your code can create.

## Let your AI agent take the routine work

```bash
curl https://postboost.co/app/api/{workspaceUuid}/accounts \
  -H "Authorization: Bearer YOUR_API_TOKEN"
```

"List my connected accounts and draft a test post to the first one." (MCP tools: `list-accounts`, `create-post`)

Your agent works in the same calendar as your team. New posts stay drafts until you or the agent schedule them. Set up your agent: https://postboost.co/agents.md

## Which plan fits

**Free**: $0/month, 3 social accounts, 1 team member, 3 scheduled posts. No credit card required.

Build and test on Free: the API and webhooks are included. Pick a paid plan when you need more accounts or unlimited scheduled posts.
