How to call the Pixverse C1 API

Pixverse C1 runs through POST /v1/videos/generations. The request returns a job_id right away; poll GET /v1/jobs/{job_id} until the job completes and read the output URLs from the result. Get an API key from the EmpirioLabs dashboard.

curl https://api.empiriolabs.ai/v1/videos/generations \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "pixverse-c1",
    "prompt": "Describe what you want Pixverse C1 to generate."
  }'

curl https://api.empiriolabs.ai/v1/jobs/JOB_ID \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY"

import requests

response = requests.post(
    "https://api.empiriolabs.ai/v1/videos/generations",
    headers={"Authorization": "Bearer YOUR_EMPIRIOLABS_API_KEY"},
    json={
        "model": "pixverse-c1",
        "prompt": "Describe what you want Pixverse C1 to generate.",
    },
)
job = response.json()

# Generation runs as an async job. Poll until it completes.
import time
while True:
    status = requests.get(
        f"https://api.empiriolabs.ai/v1/jobs/{job['job_id']}",
        headers={"Authorization": "Bearer YOUR_EMPIRIOLABS_API_KEY"},
    ).json()
    if status.get("status") in ("completed", "failed"):
        print(status)
        break
    time.sleep(5)

Good to know

PixVerse C1 is the cinematic tier, tuned for physically grounded character motion, action choreography and effects work, with automatic storyboarding from the prompt.

Modes

• t2v: text to video.
• i2v: animate a single image.
• transition: interpolate between a first-frame and a last-frame image.
• reference: combine up to 7 reference images, including multi-panel storyboard frames.

Output

• 360p, 540p, 720p and 1080p, 1 to 15 seconds.
• Aspect ratios 16:9, 4:3, 1:1, 3:4, 9:16, 2:3, 3:2 and 21:9 on text-to-video and reference modes. Image-driven modes follow the source image.
• Set generate_audio_switch to true for native synchronized audio.

Billing

• Billed per second of generated video at the rate for the output resolution, with a higher rate when audio is on.

Input limits

• Images: PNG, JPEG or WebP, up to 20MB and 10000px on the long edge.

C1 does not support clip extension. Use PixVerse V6 for that.
