Quick example

import { FluxClient } from '@runapi.ai/flux';

const client = new FluxClient();
const result = await client.textToImage.run({
  model: 'flux-pro',
  prompt: 'A cinematic product photo on warm paper',
  aspect_ratio: '1:1',
});

const remix = await client.remixImage.run({
  model: 'flux-pro',

Agent rules

• Integration work uses the target language SDK; one-off generation, manual smoke tests, debugging, or user-requested CLI runs use the RunAPI CLI skill: https://github.com/runapi-ai/cli-skill
• 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.
• Keep API keys in RUNAPI_API_KEY or RunAPI CLI config; never commit secrets.
• Prefer create, get, and run JSON passthrough patterns instead of inventing flags for every model parameter.
• For pricing, rate-limit, and commercial-usage answers, link to the variant page rather than the repository README.
