Veo 3 pricing — what does it cost per clip through the API instead of a subscription?

If you search in Korean for Veo 3 pricing, you usually end up with subscription information — Google AI Pro/Ultra plans and Flow credits. That is only half the story; the other half is missing. This article puts numbers on the missing side — how much it costs to call the API on a per-clip basis — and decides which option is better with one division.

Two pricing systems

Subscription prices and credit amounts change frequently, so we do not reproduce them here. Instead, we provide only the division needed for comparison — monthly fee ÷ per-clip price = the break-even number of clips. In months when you create fewer than that, pay-as-you-go is cheaper.

Per-clip price — by tier

The rates below are read from the model catalog. If pricing changes, this table changes too.

The biggest cost reduction comes from mixing tiers. Run the pre-finalization stage several times with Veo 3.1 Lite, then run only the finalized prompt once at a higher tier. The difference between $0.18+ and $1.60+ becomes your experimentation cost.

Calling — only the asynchronous nature matters

Unlike text, video is an asynchronous task. The request first returns a task id, and you poll that id while waiting for completion.

# 클립 하나를 만들고 결과를 기다리는 최소 예제.
# 구독도, Google Cloud 프로젝트도 없이 키 하나로 호출합니다.
import os, time, requests

KEY = os.environ["KUNAVO_API_KEY"]

# 제출하면 작업 id와 status "queued"가 바로 돌아옵니다.
job = requests.post(
    "https://api.kunavo.com/v1/videos",
    headers={"Authorization": f"Bearer {KEY}"},
    json={
        "model": "veo-3",
        "prompt": "비 오는 서울 골목, 네온 간판, 카메라가 천천히 전진",
    },
).json()

# 영상 생성은 비동기입니다 — 작업 id로 폴링합니다.
while True:
    r = requests.get(
        f"https://api.kunavo.com/v1/videos/{job['id']}",
        headers={"Authorization": f"Bearer {KEY}"},
    ).json()
    if r["status"] in ("completed", "failed"):
        break
    time.sleep(5)

# 완료되면 영상 URL은 output.url에 있습니다.
print(r["output"]["url"] if r["status"] == "completed" else r["error"])

Failed requests are not billed. However, generating again because you dislike the result is a successful generation, so each one is billed.

Honestly — when this path is not the right fit

The gateway path lets you start without a Google account or Cloud project, but it uses shared capacity rather than dedicated project quota. If you need guaranteed quota or a contractual SLA at your scale, apply directly to Google. This page does not claim to replace that option.

Image pricing is covered in the Nano Banana API; detailed English documentation is available in Veo 3 API and Text-to-video API. Payment methods are covered in Claude API pricing and billing.
