Submit a text to video job

This program submits the job, polls every 3 seconds until it finishes and prints the video URL. Swap the prompt and settings for your own.

import os, time, requests

API = "https://cheapergen.com/api/v1"
headers = {"Authorization": f"Bearer {os.environ['CHEAPERGEN_API_KEY']}"}

# 1. Submit the job
job = requests.post(f"{API}/run/pixverse/pixverse-v6/text-to-video", headers=headers, json={
    "prompt": "A cute clay-animation fox bakes a pie in a tiny kitchen, stop-motion style, warm light",
    "aspect_ratio": "16:9",
    "resolution": "540p",
    "duration": 5
}).json()

# 2. Poll until it finishes (or pass "webhook_url" and skip polling)
while job["status"] in ("queued", "running"):
    time.sleep(3)
    job = requests.get(f"{API}/generations/{job['id']}", headers=headers).json()

print(job["status"], job["output"]["video"]["url"] if job["status"] == "succeeded" else job["error"])

Get the result

A job moves from queued to running to succeeded, failed or canceled. Poll GET /api/v1/generations/{id}, or pass webhook_url and we POST the result to you. Download the output and store it yourself.

FAQ

PixVerse V6 API questions

No. The API is plain HTTPS with JSON, so the Python (requests) and Node.js (fetch) examples on this page are complete programs. Any language that can send an HTTP request works.

Yes. Add "webhook_url" to the request body and we POST the finished generation to it, signed with a CheaperGen-Signature header (HMAC-SHA256 of the timestamp and raw body). Polling GET /api/v1/generations/{id} works too.

Pass public URLs in "image_url", "reference_image_urls". Files without a public URL can be uploaded first with POST /api/v1/uploads, which returns a URL to use in the request.

Text to Video starts at $0.0176/s; the example request on this page costs $0.13, 15% below the official price. Failed generations are refunded automatically.
