Flux Kontext API Ruby SDK for RunAPI

The flux kontext api Ruby SDK is the language-specific package for Flux Kontext on RunAPI. Use this flux kontext api package for text-to-image, image editing, and creative production flows when your application needs JSON request bodies, task status lookup, and consistent RunAPI errors in Ruby.

This flux kontext api README is the Ruby package guide inside the public flux-kontext-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/flux-kontext; for API reference, use https://runapi.ai/docs#flux-kontext; for SDK docs, use https://runapi.ai/docs#sdk-flux-kontext.

Install

gem install runapi-flux-kontext

Quick start

require "runapi-flux-kontext"

client = RunApi::FluxKontext::Client.new
task = client.generations.create(
  # Pass the Flux Kontext JSON request body from https://runapi.ai/docs#flux-kontext.
)
status = client.generations.get(task.id)

Use create when you want to submit a task and return quickly, get when you need the latest task state, and run when a script should create and poll until completion. In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

Language notes

Use Ruby keyword arguments and the RunApi::FluxKontext error classes when building image jobs, Rails workers, or scripts. The available resources include generations. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
