  • Signed

    Forgeries bounce. Every request carries an HMAC-SHA256 signature over its timestamp and body: one check against your secret, and anything forged or replayed is gone.

  • Retried and logged

    A DM lands mid-deploy? We knock again, up to five times under one delivery ID, and keep every attempt on record so you can resend whatever you missed.

  • One envelope

    One shape to parse. A Telegram DM, an Instagram comment and a post going live all arrive as the same event and data pair, and each endpoint hears only what you pick.

Frequently asked questions.

Everything you need to know before integrating.

What platforms does SocialAPI.ai support?

SocialAPI.ai supports 13 platforms: the major social networks, the messaging apps customers write from, and Google Business Profile reviews. Every one of them is available on every plan, Free included. One call publishes to every platform that takes posts, and everything that comes back (comments, DMs, mentions, reviews) arrives in the same Interaction JSON shape, so you work with one schema regardless of source.

Is there a free tier? Do I need a credit card?

Yes. The Free plan gives you 2 social profiles, 10 posts/month, and 50 interactions/month across all platforms, including replies, DMs, and the MCP server. No credit card required. All paid plans include unlimited posts and interactions.

What is a social profile?

A social profile represents one end customer, brand, or location. Connect it to one or more social networks (Instagram, TikTok, LinkedIn, X, and more). Even when it connects multiple networks, it counts as one social profile for pricing. Each social profile can hold one account per platform.

What happens when I hit my monthly limit?

The Free plan has monthly limits (10 posts, 50 interactions). Once reached, write API calls return a 429 error until the limit resets at the start of your next billing period. All paid plans have unlimited posts and interactions, so there are no limits to hit. Read calls (get comments, get reviews, etc.) are always unaffected on all plans.

How does the MCP server work?

The MCP (Model Context Protocol) server exposes every API capability as one of 75+ typed tools your AI agent can call, including social_api_list_post_comments, social_api_send_dm, social_api_reply_to_review, and more. It is listed on every major MCP marketplace (Smithery, Composio, MCP.so, PulseMCP, and others) and works with any MCP-compatible host, including Claude, ChatGPT, Cursor and open-source orchestrators.

Can I switch plans at any time?

Yes. You can upgrade or downgrade at any time. Upgrades take effect immediately; downgrades apply at the next billing cycle.

Who built SocialAPI.ai?

SocialAPI.ai is built and run by Erwan Prost, a French software engineer. He has been writing Go since 2020 and publishes open-source infrastructure tooling on GitHub, including azuretls-client (461+ stars). From 2023 to 2025 he built and ran CapitalSync, a trade copier platform that ran on Kubernetes with a custom operator he wrote in Go. He works on SocialAPI.ai full-time.

Ready to unify your social interactions?

Free tier available. No credit card required. Ships with the MCP server.
