Other

Generate and edit images with Flux Kontext through RunAPI. Use when the user asks an agent to create, edit, or transform images with Flux Kontext. Default to the RunAPI CLI for one-off generation; use SDKs only when the user is integrating RunAPI into an app or backend.

Flux Kontext on RunAPI

Generate and edit images with Flux Kontext through RunAPI. The default path for one-off agent tasks is the runapi CLI; SDKs are for application integration.

Routing decision

  • One-off generation, editing, or transformation for the user → use the CLI path with the runapi binary.
  • Building an app, backend, worker, library, or production codebase → use the SDK integration path.

CLI path

The runapi binary is the runtime dependency. Authenticate with runapi login (browser) or set RUNAPI_API_KEY; a saved CLI config also works — no required environment variable.

Inspect the available actions and request fields with CLI help:

runapi flux-kontext --help
runapi flux-kontext text-to-image --help

Run a one-off task (synchronous — polls until the task completes):

runapi flux-kontext text-to-image --input-file request.json

Submit asynchronously and poll separately:

runapi flux-kontext text-to-image --async --input-file request.json
runapi wait <task-id> --service flux-kontext --action text-to-image

Available actions: text-to-image.

SDK integration path

When integrating Flux Kontext into an app, backend, worker, or library — not for one-off tasks — use a RunAPI SDK package:

  • JavaScript / TypeScript: @runapi.ai/flux-kontext
  • Ruby: runapi-flux_kontext
  • Go: github.com/runapi-ai/flux-kontext-sdk/go
