Z-Image Python SDK for RunAPI

The Z-Image Python SDK is the language-specific package for Z-Image on RunAPI. Use it for text-to-image flows when your application needs JSON request bodies, task status lookup, and consistent RunAPI errors in Python.

For model details, use https://runapi.ai/models/z-image; for API reference, use https://runapi.ai/docs#z-image; for SDK docs, use https://runapi.ai/docs#sdk-z-image.

Install

pip install runapi-z-image

Quick start

from runapi.z_image import ZImageClient

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

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

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="z-image",
    prompt="A serene mountain lake at dawn",
    aspect_ratio="1:1",
)
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 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.z_image error classes when building image jobs or scripts. The available resource is text_to_image. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
