Mountsea AI API Introduction

Discover all you can do with our Mountsea AI API! Our comprehensive AI platform empowers developers to integrate advanced AI capabilities into their applications — including video generation, image creation, music production, and multi-model LLM chat.

Overview

Mountsea AI provides a unified API gateway to access the world’s leading AI models across video, image, music, and language domains. We offer six core services:

Google (Gemini)

Video & image generation powered by Veo 2 / Veo 3 / Veo 3.1 and Nano Banana models

Sora2

OpenAI’s Sora-2 / Sora-2-Pro text-to-video generation with character roles

XAI (Grok)

Image & video generation powered by xAI’s Grok models

Suno

Full-suite AI music generation, voice persona, custom model training, and audio processing via Suno AI

ElevenLabs

AI music generation with composition plans, video scoring, and stem separation via ElevenLabs

Producer

AI music generation powered by Google DeepMind’s Lyria 3 Pro model

Chat

Multi-protocol AI chat gateway supporting OpenAI, Claude, and Gemini APIs

Why Mountsea AI Stands Out

All-in-One API Platform

A single API key gives you access to multiple AI services across different domains — no need to manage separate accounts and credentials for each AI provider.

Multi-Protocol LLM Gateway

Our Chat service supports OpenAI Compatible API, Anthropic (Claude) API, OpenAI Responses API, and Google Gemini Native API. Use official SDKs directly — just change the base_url.
