How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

Output

Returns the processed image binary (or equivalent) with the text watermark applied. The output format matches the input by default, or can be overridden. For lossy formats, quality can be controlled. The watermark can appear at a specific position or tiled across the image in a staggered grid pattern.

Example use cases

“Watermark this product image at https://example.com/product.jpg with '© AcmeCorp 2025' in white at 50% opacity, placed at the bottom-right, and give me back a JPEG.”

Tiled brand stamp across marketing assets

“Apply a tiled 'CONFIDENTIAL' watermark in red (#ff0000) at 30% opacity, angled 45 degrees, across this image at https://cdn.example.com/slide.png — output as PNG.”

Diagonal draft watermark on a preview image

“Stamp the word 'DRAFT' diagonally at a 30-degree angle, centered, in gray (#888888) at 60% opacity, on this base64 image — keep the output in the original format.”

When to prefer

Choose this endpoint when you need server-side, programmatic text watermarking of images without requiring any local image processing libraries or GPU resources. It's ideal for agents that need to protect, brand, or annotate images on the fly, supporting both single-placement and tiled patterns with fine-grained control over appearance. Prefer this over client-side solutions when operating in a stateless agent pipeline.

Side effects

Image URL not publicly accessible or larger than 10 MB — returns error
Base64 payload exceeds 13 MB limit — returns error
Invalid color hex code format — validation error
Font size or angle out of allowed range — validation error
Unsupported output format requested — validation error
Watermark text empty or exceeds 200 characters — validation error
Network timeout fetching remote image URL — returns error

Input

Schema · Request body

Field	Type	Description
url	—	Public http(s) URL of the image (at most 10 MB; private, internal and IP-literal hosts are refused); or use image_base64.
text	string	1-200 printable characters.
tile	boolean	A staggered grid (at most 2,500 marks).
angle	number	Text rotation in degrees, clockwise (-180 to 180, default 0).
color	string	Text colour as #rrggbb or #rrggbbaa (default #ffffff).
format	—	Output format (default: the input's; ICO in, PNG out).
margin	—	Pixels from the edge (default half the font size, at least 4); with tile, the gap between marks.
output	string	base64 (default): the file comes back inline as base64. url: the file is stored for 24 hours and the reply carries a download link (url, expires_at, bytes, content_type, sha256) instead of the base64, which keeps the file out of your context window.
opacity	number	0 (invisible) to 1 (opaque); default 0.5.
quality	—	Encoder quality 1-100 (lossy formats).
position	string	Single mark's place: center, top, bottom, left, right, top-left, top-right, bottom-left or bottom-right (default).
font_size	—	Default: 5% of the short side.
auto_orient	boolean	Apply the EXIF orientation first.
image_base64	—	The image as standard or url-safe base64 (at most 10 MB decoded; a data:image/...;base64, prefix is fine); or use url.
