GPT Image API for AI Image Generation

What this page helps you do

GPT Image API for AI Image Generation explains how to use APIsRouter as one OpenAI-compatible API gateway instead of wiring every model provider separately. It focuses on Base URL setup, model IDs, billing behavior, and where to inspect request logs.

• Keep your OpenAI SDK or compatible client structure.
• Switch models through the model field instead of changing application code.
• Use one account balance and one console to inspect usage and errors.

OpenAI SDK example

Most SDKs and agent tools only need the Base URL, API key, and model ID.

from openai import OpenAI

client = OpenAI(
    api_key="sk-...",
    base_url="https://api.apisrouter.com/v1",
)

response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[{"role": "user", "content": "Reply with one sentence if the connection works."}],
)

print(response.choices[0].message.content)

When to use it

Use this route when you want a lower-friction model API setup for coding agents, chat products, internal tools, or scripts that need multiple model families behind one compatible API.
