FAQs • ArtenoMark Docs

What is ArtenoMark?

ArtenoMark is a flexible and powerful image watermarking API. It allows you to apply text or image watermarks to your images programmatically or through a frontend interface.

Who is ArtenoMark for?

For developers, designers, and creators who want fast, customizable watermarking – whether you're batch-processing images, protecting your work, or branding visuals.

Is ArtenoMark free?

You get 10 free watermarking requests per day via RapidAPI. Beyond that, you'll need to subscribe to a paid tier (check RapidAPI pricing for details).

What formats are supported?

Currently supports most common formats: .jpg, .jpeg, .png, and .webp.

Do I need an API key?

Yes. If you're using ArtenoMark via RapidAPI, you'll need your RapidAPI key to authenticate every request. RapidAPI manages rate limits and analytics too.

What kind of inputs can I use?

You can use image URLs, base64-encoded images or form uploads (via multipart/form-data).

What kind of watermarks can I add?

You can add:

Text watermarks (custom fonts, colors, sizes, angles)
Image watermarks (like logos or stamps)
Support for rotation, transparency, positioning, and margin tweaking

What do I get in the response?

You'll get:

A URL to the watermarked image (temporary, hosted via Vercel Blob)
Content-type metadata
Optional file download name

Getting a “400 Bad Request”?

That usually means:

A required parameter is missing
The image source is invalid
The request body isn't properly formatted

How long are the images stored?

For privacy, all images are auto-deleted after 15 minutes from upload.

Do we collect your data?

Nope. We don’t store your data permanently. We only keep the images temporarily for watermarking and delivering the output. See our Privacy Policy for more.

Is my IP exposed?

Not directly. If you're using it client-side only, your IP may be visible to RapidAPI (they manage the traffic), but ArtenoMark itself doesn't log it.

Getting a “400 Bad Request”?

That usually means:

A required parameter is missing
The image source is invalid
The request body isn't properly formatted

Can I use ArtenoMark from mobile/web apps?

Yep! Just make sure your API key is protected (e.g., through a backend proxy or serverless function), especially if you're calling the API from frontend code.

Can I integrate ArtenoMark with other services?

Totally. You can chain it into image pipelines (like upload -> watermark -> CDN), automation tools, CMS plugins, etc.

My watermark is not showing. What do I do?

Check:

The image format (must be supported)
That the watermark isn't fully transparent (or opacity is low)
Position/margins — it may be pushed outside the image bounds
