Why Use Both Platforms
Overflow Capacity
Hit your Runway credit limit? CreativeAPI picks up the overflow with Kling/Veo. Never wait for credits to reset.
Multi-Model Testing
Not sure which model fits your content? A/B test Kling, Seedance, Veo in parallel. Find what works for your use case.
No Single Point of Failure
Runway outage? CreativeAPI fails over automatically. Your demo pipeline stays live.
Same Async Architecture
Webhook completion, job tracking, status polling — identical to Runway. Minimal code changes.
Supersonik — Perfect Technical Fit
AI sales demo agent using Runway for personalized video. They need exactly what we provide: multi-model failover + webhook completion + batch overflow capacity.
Pitch: "Runway for Gen-4 specific demos. CreativeAPI for Kling/Veo batch overflow. Multi-model failover means your demo pipeline never goes down."
Same Architecture, Different Models
// Your existing Runway flow (keep it)
const runwayVideo = await runway.generate({
model: 'gen-4',
prompt: scenePrompt,
webhook_url: WEBHOOK_URL
});
// Add CreativeAPI overflow (new)
if (runwayCredits < THRESHOLD) {
const overflowVideo = await creativeAPI.videos.generate({
model: 'auto', // Multi-model failover
prompt: scenePrompt,
duration: 5,
webhook_url: WEBHOOK_URL // Same webhook architecture
});
}
// Identical webhook handler for both
app.post('/webhook/video-complete', (req, res) => {
const { id, output_url, model_used } = req.body;
// Works for Runway OR CreativeAPI
updateScene(id, output_url, model_used);
