How pricing works for Veo 3.1 Lite (1080p)

Veo 3.1 Lite (1080p) is billed per second of generated video — $0.0800 per second of video, charged when the render is submitted. There is no monthly fee; the clip's `duration` is the billed quantity, so a 5-second clip costs five times the published per-second rate.

Calling Veo 3.1 Lite (1080p) on KeepRouter

Point a compatible client at the supported KeepRouter endpoint and set the model to veo-3.1-lite-1080p. KeepRouter preserves the client-facing request shape while handling upstream routing or translation. Submit the render to POST /v1/video/generations, then poll GET /v1/videos/{id} until status is completed and read url.

cURL

# 1. Submit the render and keep the task id
TASK=$(curl -s https://keeprouter.com/v1/video/generations \
  -H "Authorization: Bearer $KEEPROUTER_KEY" -H "Content-Type: application/json" \
  -d '{"model":"veo-3.1-lite-1080p","prompt":"a paper plane gliding over a sunlit desk","duration":4}' \
  | python3 -c 'import json,sys; print(json.load(sys.stdin)["id"])')
# 2. Poll until the clip is ready
curl -s https://keeprouter.com/v1/videos/$TASK -H "Authorization: Bearer $KEEPROUTER_KEY"

Python

import os, time, requests
headers = {"Authorization": "Bearer " + os.environ["KEEPROUTER_KEY"]}
task = requests.post("https://keeprouter.com/v1/video/generations", headers=headers, json={
    "model": "veo-3.1-lite-1080p", "prompt": "a paper plane gliding over a sunlit desk", "duration": 4,
}).json()
while True:
    state = requests.get(f"https://keeprouter.com/v1/videos/{task['id']}", headers=headers).json()
    if state["status"] in ("completed", "failed", "canceled"):
        break
    time.sleep(5)
print(state["url"] or state["error"])

JavaScript

const headers = { Authorization: "Bearer " + process.env.KEEPROUTER_KEY, "Content-Type": "application/json" };
const task = await (await fetch("https://keeprouter.com/v1/video/generations", {
  method: "POST", headers,
  body: JSON.stringify({ model: "veo-3.1-lite-1080p", prompt: "a paper plane gliding over a sunlit desk", duration: 4 }),
})).json();
let state;
do {
  await new Promise((r) => setTimeout(r, 5000));
  state = await (await fetch("https://keeprouter.com/v1/videos/" + task.id, { headers })).json();
} while (state.status !== "completed" && state.status !== "failed" && state.status !== "canceled");
console.log(state.url ?? state.error);

Estimate API costs

At the current KeepRouter customer price, an example workload of 6 seconds of generated video per request costs approximately $0.4800 per request. At 100 requests per day, that is $1440.00 over 30 days. This is a usage estimate, excluding processing fees, taxes, retries and application infrastructure. Actual usage, cache hits and supported generation durations need their own checks.

How to evaluate Veo 3.1 Lite (1080p)

Veo 3.1 Lite (1080p) is listed on KeepRouter as text-to-video under the exact id veo-3.1-lite-1080p. Use POST /v1/video/generations, then GET /v1/videos/{id} for the listed route; a maker's upstream features do not automatically apply to this gateway endpoint. No context limit is asserted here because the exact upstream limit has not been verified for this catalog entry.

First workload: Render one short representative clip, then inspect motion, consistency and the billed duration. Accepted durations on this route: 4, 6, 8 seconds.

Before production: Video generation is asynchronous and billed by generated seconds. Poll the task result; keep failed or refused jobs separate in your cost accounting.

Public model usage evidence

No public, exact-variant usage figure has been verified for this KeepRouter model id. Missing data is not zero usage; family-level or maker-wide traffic is not presented as this model's traffic.

Published examples and cases

No exact-model customer case has been verified for this entry. The workload above is an evaluation recipe, not a claim of a public deployment.
