Imagen 4 API Python SDK for RunAPI

The Imagen 4 Python SDK is the language-specific package for Imagen 4 on RunAPI. Use this package for image generation, image editing, and creative production workflows when your application needs request bodies, task status lookup, and consistent RunAPI errors in Python.

This README is the Python package guide inside the public imagen-4-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/imagen-4; for API reference, use https://runapi.ai/docs/api/imagen-4/text-to-image; for SDK docs, use https://runapi.ai/docs/resources/sdks.

Install

pip install runapi-imagen-4

Quick start

from runapi.imagen_4 import Imagen4Client

client = Imagen4Client()  # reads RUNAPI_API_KEY, or pass api_key="sk-..."

task = client.text_to_image.create(
    model="imagen-4",
    prompt="A neon city street after rain, cinematic",
    aspect_ratio="16:9",
)
status = client.text_to_image.get(task.id)

remix = client.remix_image.create(
    model="imagen-4-pro-remix-image",
    prompt="Make it golden hour",
    source_image_urls=["https://cdn.runapi.ai/public/samples/image.jpg"],
)

Use create to submit a task and return quickly, get to fetch the latest task state, and run to create and poll until completion:

result = client.text_to_image.run(
    model="imagen-4",
    prompt="A serene mountain lake at dawn",
)
print(result.images[0].url)

In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

RunAPI-generated file URLs are temporary. Download and store generated images, videos, audio, or other files in your own durable storage within 7 days; do not treat returned URLs as long-term assets.

Language notes

Pass parameters as keyword arguments and catch the runapi.imagen_4 error classes when building image jobs or scripts. The available resources are text_to_image and remix_image. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
