Usage

All media models use the async job queue. Submit a job, then poll for the result.

Step 1: Submit Job

Image-to-Video

Pass a starting image via imageData to animate it. This model is image-to-video only, so imageData is required.

const res = await fetch('https://api.yepapi.com/v1/media/queue', {
  method: 'POST',
  headers: {
    'x-api-key': 'YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'kwaivgi/kling-v2.5-turbo-std',
    prompt: 'Animate this scene — clouds drifting, light changing',
    options: {
      duration: '5',
      params: {
        negative_prompt: 'blurry, low quality, distorted faces',
      },
    },
    imageData: {
      mimeType: 'image/jpeg',
      base64: '...', // Base64-encoded image
    },
  }),
});
const { data } = await res.json();
// data.jobId — use this to poll for results

curl -X POST https://api.yepapi.com/v1/media/queue \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "kwaivgi/kling-v2.5-turbo-std", "prompt": "Animate this scene — clouds drifting, light changing", "options": {"duration": "5", "params": {"negative_prompt": "blurry, low quality, distorted faces"}}, "imageData": {"mimeType": "image/jpeg", "base64": "..."}}'

Step 2: Poll for Result

const status = await fetch(`https://api.yepapi.com/v1/media/status/${data.jobId}`, {
  headers: { 'x-api-key': 'YOUR_API_KEY' },
});
const { data: job } = await status.json();
// job.status — "pending" | "processing" | "completed" | "failed"
// job.result.video — { mimeType, base64 } when completed

curl https://api.yepapi.com/v1/media/status/JOB_ID \
  -H "x-api-key: YOUR_API_KEY"

Pricing

Tier	≈ Cost/sec	5-second video
All requests	$0.072	$0.36

Prices shown are for a 5-second clip at the default settings; longer clips cost proportionally more. Each job is priced when it's queued — the exact quote for your duration, resolution and options — and charged only if it succeeds. Failed or moderated jobs are free.

Info

Video jobs can take several minutes to complete. When capacity is busy, jobs wait in the queue (status stays pending or processing) — no action needed. Results retained for 1 hour.
