Usage

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

Step 1: Submit Job

Text-to-Video

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: 'bytedance/seedance-2.0-mini',
    prompt: 'A cinematic drone shot over a rugged coastline at golden hour',
    options: {
      aspectRatio: '16:9',
      resolution: '720p',
      duration: '5',
      generateAudio: true,
    },
  }),
});
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": "bytedance/seedance-2.0-mini", "prompt": "A cinematic drone shot over a rugged coastline", "options": {"aspectRatio": "16:9", "resolution": "720p", "duration": "5", "generateAudio": true}}'

Image-to-Video

Pass a reference image via imageData with an imageRole (first_frame or last_frame) to generate a video from a still image.

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: 'bytedance/seedance-2.0-mini',
    prompt: 'Animate this scene — clouds drifting, light changing',
    options: {
      aspectRatio: '16:9',
      resolution: '720p',
      duration: '5',
      generateAudio: true,
      imageRole: 'first_frame',
    },
    imageData: {
      mimeType: 'image/jpeg',
      base64: '...', // Base64-encoded image
    },
  }),
});

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

Token-based billing. Cost varies by resolution and duration.

Tier	Cost/sec
480p (typical)	~$0.07

Example: 5-second 480p video ≈ 5 x $0.07 = **$0.35**. Billing is dynamic — each job is billed from the actual cost of the finished video, so shorter or lower-resolution jobs cost less.

Info

Video jobs can take several minutes to complete. Results retained for 1 hour.
