Gemini Watermark Remover API

Clean Gemini images in your own app, script or pipeline. Send the image in one POST request and get the PNG back, with the sparkle logo removed and the original resolution kept. It uses the same engine as our free online remover.

Quickstart

1. Get a key. Request access; we reply with your key by email. Keep it secret and send it only from your server.
2. Send the image. POST the raw PNG or JPEG bytes to the endpoint with your key in the Authorization header.
3. Save the result. A 200 response body is the cleaned PNG.

Examples

cURL

curl -X POST https://the-ai-future.com/api/v1/remove-gemini-watermark \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: image/png" \
  --data-binary @gemini-image.png \
  -o gemini-image-no-watermark.png

JavaScript (Node 18+)

import { readFile, writeFile } from 'node:fs/promises';

const res = await fetch('https://the-ai-future.com/api/v1/remove-gemini-watermark', {
  method: 'POST',
  headers: { Authorization: 'Bearer ' + process.env.GWR_API_KEY, 'Content-Type': 'image/png' },
  body: await readFile('gemini-image.png'),
});
if (res.ok) await writeFile('gemini-image-no-watermark.png', Buffer.from(await res.arrayBuffer()));
else console.error(res.status, await res.json()); // e.g. 422 no_watermark_found

Python

import os, requests

with open("gemini-image.png", "rb") as f:
    r = requests.post("https://the-ai-future.com/api/v1/remove-gemini-watermark",
        headers={"Authorization": f"Bearer {os.environ['GWR_API_KEY']}", "Content-Type": "image/png"},
        data=f.read(), timeout=60)
if r.ok:
    open("gemini-image-no-watermark.png", "wb").write(r.content)
else:
    print(r.status_code, r.json())

Limits and Usage

• Daily limit: each key has a daily image limit (500 by default), reset at 00:00 UTC. Every accepted image counts, including ones where no watermark was found. Need more? Ask us.
• One image per request. For batches, send requests one after another or a few at a time.
• Privacy: images are processed in memory and never stored or logged. Only a count of requests per key is kept.
• What it removes: the visible Gemini sparkle logo only. Google’s invisible SynthID watermark stays in the image.
• Fair use: use it on images you generated with Gemini or have the right to edit. Don’t use it to pass off AI images as human-made.
