Capability Shelf

Plug capabilities into your own AI assistant

We package APEX capabilities in three integration forms — SDK, MCP and SKILL — so your AI assistant (agent) can use them directly, with no data source to wire up yourself.

Go to the developer center: direct API calls & full endpoint docs

Three integration forms

Pick the one that fits how you build: install the SDK, connect over MCP, or just give your assistant a SKILL.

Coming soon

SDK

Call APEX capabilities as functions from your own code.

Coming soon

MCP

Connect APEX capabilities to any MCP-aware assistant over the MCP protocol.

Available

SKILL

Give your AI assistant a skill it can invoke in one sentence — nothing to wire up.

SKILL

Available skills

Once installed, invoke it with one natural-language sentence; under the hood it runs on APEX's capability API with your own sk- key.

Douyin data fetch

Pull or search public Douyin posts from your own AI assistant in one sentence — no data source to wire up yourself.

Agnes image & video

Wire it into your own AI assistant to give the agent image- and video-generation — describe it in a sentence and it's generated, nothing to wire up.

Use it in your assistant like this

Use Agnes to generate a Shiba Inu running through a neon city at night, 16:9 cinematic.

Under the hoodThe skill calls APEX's capability API, billed per call with your own sk- key.

The SKILL calls APEX's public capability API; billing, rate limiting and auth reuse the platform's shared wallet and sk- key system. The SDK and MCP forms are coming soon.
