# 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:

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

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

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

Submit asynchronously and poll separately:

```shell
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`
