元任务 AI 网关 (Metask AI Gateway) is a unified AI API gateway that lets you access multiple large language models through a single, OpenAI-compatible API endpoint. Instead of juggling separate accounts and API keys for each AI provider, you connect once and route requests to any supported model.

Quick Start

Make your first AI API call in minutes using your gateway API key.

Authentication

Learn how to obtain and use your API key to authenticate requests.

Available Models

Browse all AI models available through the gateway.

API Reference

Full reference for the chat completions and models endpoints.

How it works

元任务 AI 网关 sits between your application and AI providers. You send requests to the gateway using the standard OpenAI API format, and the gateway routes them to the correct underlying model — handling authentication, rate limiting, and token accounting on your behalf.
1

Create an account

Register at napi.origintask.cn to get access to the gateway.
2

Get your API key

Generate an API key from your dashboard. This key authenticates all your requests to the gateway.

Key benefits

  • Single endpoint — One base URL and one API key for all models, no per-provider setup needed.
  • OpenAI-compatible — Drop-in replacement for the OpenAI API. Change the base URL and your existing code works.
  • Multiple models — Access models from multiple AI providers through the same interface.
  • Usage tracking — Monitor token consumption and costs in real time from your dashboard.
  • Flexible billing — Top up your balance, use promo codes, or subscribe to a plan.
元任务 AI 网关 uses an OpenAI-compatible API format, meaning any library or tool that supports OpenAI’s API will work with the gateway by simply changing the base_url.
