SocialAPI.ai is a social media API you can connect to ChatGPT as a Custom GPT Action. Import the OpenAPI schema, add your API key, and ChatGPT can read comments, send DMs, publish posts, and reply to reviews across Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads with no per-platform code.
A Custom GPT can only call tools you expose as an Action, which means hosting an API, writing an OpenAPI spec, and handling OAuth for every network before ChatGPT can do anything. SocialAPI.ai is one pre-built API with a published OpenAPI schema, so you import it as an Action, paste your key, and ChatGPT can act across every connected network without any backend work.
Import the OpenAPI schema once and every endpoint becomes a callable Custom GPT Action.
ChatGPT can list, reply to, hide, and like comments across all connected platforms.
Read conversations and send replies through a single messaging endpoint.
Create and schedule posts across every network from one action call.
Read and reply to reviews so ChatGPT can manage reputation in one place.

Create a GPT, open Actions, and import the SocialAPI.ai OpenAPI schema. Set authentication to API Key with a Bearer token. ChatGPT can then call any endpoint as an action.
ChatGPT Actions are defined by an OpenAPI schema. SocialAPI.ai publishes one, so you point a GPT at the schema URL, add your API key as a Bearer token, and every social capability becomes an action ChatGPT can call. There is no server to deploy and no per-platform OAuth code to write.
Because SocialAPI.ai normalizes Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads behind one API, a single imported Action lets ChatGPT read and respond across all of them. The same call shape returns the same JSON for every platform, which keeps the GPT's tool use accurate.
Custom GPTs use Actions over REST, while assistant clients that speak Model Context Protocol can use the SocialAPI.ai MCP server instead. If you are building an MCP-native agent rather than a Custom GPT, see the Social Media API for AI Agents page at https://social-api.ai/solutions/social-media-api-for-ai-agents.
Once you connect accounts, ChatGPT can publish, reply, and message within each network's rules. SocialAPI.ai enforces per-platform scopes and rate limits behind the scenes, so the GPT acts safely and you keep full control through the dashboard.
Building Actions for each social network means a separate OpenAPI spec and OAuth flow per platform. SocialAPI.ai gives ChatGPT one Action for all of them. See how it compares to other approaches.
FAQ
Create a Custom GPT, open Actions, and import the SocialAPI.ai OpenAPI schema. Set authentication to API Key with a Bearer token, then connect your Instagram account in the SocialAPI.ai dashboard. ChatGPT can then read and reply to Instagram comments and DMs through the imported action.
Yes. Once SocialAPI.ai is imported as a GPT Action and your accounts are connected, ChatGPT can publish posts, reply to comments, send DMs, and respond to reviews across Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads through one set of actions.
GPT Actions let a Custom GPT call a REST API defined by an OpenAPI schema. The MCP server exposes the same capabilities as Model Context Protocol tools for assistant clients that support MCP. SocialAPI.ai offers both, so you pick the one your assistant uses.
ChatGPT can manage Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads through SocialAPI.ai. Each platform returns the same normalized JSON, so one imported action works across all of them without platform-specific handling.
Yes. SocialAPI.ai has a free tier with no credit card required, and reads such as fetching comments and DMs are always free. You can connect ChatGPT, get an instant API key, and start calling actions on the free plan.
