GlobalAI OPC: Text, Image, and Video Generation APIs

GlobalAI OPC provides video, image, and text AI generation APIs through a unified OpenAI-compatible gateway supporting Sora, VEO, Claude, GPT, and more.

GlobalAI OPC is a unified AI API gateway that lets you generate text, images, and videos through a single, consistent interface. Every endpoint is OpenAI-compatible, so you can integrate familiar tooling and SDKs while accessing a broad catalog of cutting-edge models — from OpenAI’s Sora and GPT to Google’s VEO and Gemini, Anthropic’s Claude, and a growing roster of specialized video and image generators.

Core API Categories

Text APIs

Generate and stream conversational text using GPT, Claude, and Gemini models through a single OpenAI-compatible chat completions endpoint.

Image APIs

Create high-quality images from text prompts using Nano Banana and GPT Image models, with flexible aspect ratios and resolutions up to 4K.

Video APIs

Produce AI-generated videos from text or image prompts using Sora, VEO, Seedance, Vidu, Grok, and more — with durations from 4 to 30 seconds.

Videos & SD2 Manxue

Additional specialized video generation models for diverse creative use cases.

Image Models

Model	Description
nano-banana / nano-banana-2 / nano-banana-pro	Nano Banana series — fast to professional quality, up to 4K resolution, 10 aspect ratios
gpt-image-2	GPT Image 2 — high-fidelity image generation via the GPT Image endpoint

Text Models

Model Family	Access Method	Example Models
GPT	OpenAI-compatible Chat Completions	gpt-5.4, gpt-5.5
Claude	OpenAI-compatible Chat Completions	claude-sonnet-4-5, claude-opus-4-7, claude-haiku-4-5
Gemini	OpenAI-compatible Chat Completions	gemini-2.5-pro, gemini-3-flash-preview, gemini-3.1-pro-preview

Base URLs

All GlobalAI OPC API requests go to one of two base URLs depending on the API category.

API Category	Base URL
Text (GPT, Claude, Gemini)	http://apillm.globalaiopc.com/gw_llm_power
Image & Video (Nano Banana, Sora, VEO, etc.)	https://zcbservice.aizfw.cn/kyyReactApiServer

Always use the correct base URL for the API category you are calling. Using the text base URL for an image or video endpoint — or vice versa — will result in a connection error.

Authentication

All requests to GlobalAI OPC require a Bearer token: include your API key in an Authorization: Bearer YOUR_API_KEY header on every request.

Async Task Model

Image and video generation use an asynchronous task model. When you submit a generation request, the API immediately returns a task id and a status of queued or processing. You then poll a query endpoint with the task ID until the status changes to completed (or failed), at which point the response includes the generated image URL or video URL.

Task completion time varies by model and output length. Video generation typically takes one to several minutes. Plan your integration to poll at reasonable intervals — every 30–60 seconds is a good starting point.
