Onepostly is a social media API for developers, product teams, and AI agents. One integration publishes, schedules, and measures content across nine platforms.
What it does
Send one request with text, media URLs, and destination account IDs. Onepostly handles each platform's OAuth, app registration, token refresh, and rate limits, then fans the post out to the official APIs.
Key features
- Publishing — text, media URLs, images, video, carousels, and first comments in a single call
- Scheduling —
scheduledForwith timezone support, cancellable before publish - Analytics — likes, comments, and shares from every platform in one normalized JSON shape
- Engagement — comments, DMs, and like/repost actions on the same accounts and API key
- Webhooks — publish, fail, comment, and DM events delivered as they happen
- SDKs — official TypeScript and Python clients, plus plain REST and cURL
- MCP server — lets Claude Code, Cursor, and other MCP clients create posts, schedule content, and read metrics
- White-label OAuth — consent screens use neutral product names instead of the Onepostly brand
