New REST APIs for Developers & Creators: Image Translation, Embeddings, Text, Watermark & Background Removal

We’ve shipped four highly requested computer-vision endpoints and wired them into the PixLab API, the prompt-based AI Photo Editor and the Vision Workspace (OCR). This post gives you a developer-first tour with direct docs links and working JavaScript examples you can paste into your app today.

Quick links (docs)

You’ll need an API key from the PixLab Console: https://console.pixlab.io

Also available for content creatros in the popular apps suite namely:

1) Image Text Translation API (imgtranslate)

Translate text inside the image, preserve layout, and output the same image with replaced text. Supports English ↔ 10 languages and English/Chinese ↔ other languages; auto-detect is available when you’re unsure of the source. Endpoint: https://api.pixlab.io/imgtranslate.

JS example (POST upload)

<input type="file" id="imgFile" />
<script>
const API_KEY = 'PIXLAB_API_KEY';
const API_URL = 'https://api.pixlab.io/imgtranslate';

async function translateImage(target = 'en', source = 'auto') {
  const file = document.getElementById('imgFile').files?.[0];
  if (!file) return alert('Select an image first');

  const form = new FormData();
  form.append('file', file);
  form.append('key', API_KEY);
  form.append('target', target);
  form.append('source', source);

  const res = await fetch(API_URL, { method: 'POST', body: form });
  const out = await res.json();

  if (out.status !== 200) {
    console.error(out.error);
    return;
  }

  const bytes = atob(out.imgData);
  const buf = new Uint8Array([...bytes].map(c => c.charCodeAt(0)));
  const blob = new Blob([buf], { type: out.mimeType });
  const a = Object.assign(document.createElement('a'), {
    href: URL.createObjectURL(blob),
    download: `translated.${out.extension}`
  });
  document.body.appendChild(a); a.click(); a.remove();
}
</script>

2) Image Embedding API (imgembed)

Generate high-dimensional vectors (CLIP, etc.) for similarity search, clustering, or retrieval. Simple GET with image, model, key or POST with file. Endpoint: https://api.pixlab.io/imgembed.

JS example (GET by URL)

const API_KEY = 'PIXLAB_API_KEY';
const imageUrl = 'https://i.imgur.com/0Qe9rWZ.jpg';
const model = 'clip';

const url = new URL('https://api.pixlab.io/imgembed');
url.searchParams.set('image', imageUrl);
url.searchParams.set('model', model);
url.searchParams.set('key', API_KEY);

const res = await fetch(url);
const out = await res.json();

if (out.status !== 200) {
  console.error(out.error);
} else {
  console.log('dim:', out.vector.length, 'sample:', out.vector.slice(0, 8));
}

3) Text & Watermark Removal API (txtremove)

Programmatically remove overlaid text/watermarks while preserving content. POST with file or GET with img. Endpoint: https://api.pixlab.io/txtremove.

Important use policy: do not use this endpoint to remove watermarks or branding from copyrighted material you don’t own or have rights to; doing so violates the Terms and may result in account suspension. You’re responsible for legal compliance.

JS example (POST upload)

<input type="file" id="wmFile" />
<button id="removeTextButton">Remove</button>
<script>
const API_KEY = 'PIXLAB_API_KEY';
const API_URL = 'https://api.pixlab.io/txtremove';

async function removeText() {
  const file = document.getElementById('wmFile').files?.[0];
  if (!file) return alert('Select an image first');

  const form = new FormData();
  form.append('file', file);
  form.append('key', API_KEY);

  const res = await fetch(API_URL, { method: 'POST', body: form });
  const out = await res.json();

  if (out.status !== 200) return console.error(out.error);

  const bytes = atob(out.imgData);
  const buf = new Uint8Array([...bytes].map(c => c.charCodeAt(0)));
  const blob = new Blob([buf], { type: out.mimeType });
  const a = Object.assign(document.createElement('a'), {
    href: URL.createObjectURL(blob),
    download: `clean.${out.extension}`
  });
  document.body.appendChild(a); a.click(); a.remove();
}
document.getElementById('removeTextButton')?.addEventListener('click', removeText);
</script>

4) Background Removal API (bgremove)

Isolate the subject and drop the background—great for product images, creative apps, and bulk pipelines. POST with file or GET with image. Endpoint: https://api.pixlab.io/bgremove.

JS example (GET by URL)

const API_KEY = 'PIXLAB_API_KEY';
const url = new URL('https://api.pixlab.io/bgremove');
url.searchParams.set('image', 'https://i.imgur.com/0Qe9rWZ.jpg');
url.searchParams.set('key', API_KEY);

const res = await fetch(url);
const out = await res.json();

if (out.status !== 200) {
  console.error(out.error);
} else {
  console.log('result:', out.link ?? out.imgData.slice(0, 64) + '...');
}

Works out-of-the-box in PixLab apps

Production tips

  • Pass key as query param or header.
  • Use multipart/form-data for uploads.
  • blob=true for binary output.
  • Integrate with S3 from Console for permanent storage.
  • Handle status & error fields in JSON responses.

Next steps

  1. Get your API key → https://console.pixlab.io
  2. Read the docs:
  3. Try no-code:

Happy Integration!
