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 watermarked PDF file as a binary response, with the specified text stamp applied to the requested pages using the chosen font, size, color, opacity, angle, and position settings.

Example use cases

Confidential report watermarking

“Take this PDF at https://docs.example.com/q3-report.pdf and add a diagonal 'CONFIDENTIAL' watermark in gray at 30% opacity, centered on every page, using helvetica-bold at size 60.”

Draft document labeling

“I need to mark this base64-encoded PDF as 'DRAFT' — put the watermark in the center, at a 45-degree angle, in red (#FF0000), semi-transparent at 25% opacity, so reviewers know it's not final.”

Branding first and last pages

“Stamp 'Prepared by Acme Corp' in small courier text at the bottom-center of only pages 1 and 2 of this PDF (https://files.acme.com/proposal.pdf), in dark blue (#003366), at 50% opacity, placed underneath the existing content.”

When to prefer

Choose this endpoint when you need to add a text-based watermark to a PDF with fine-grained control over font, size, color, opacity, rotation angle, position, and which pages are affected. It supports both URL-referenced and base64-encoded PDFs and allows stamping over or under existing content. Prefer this over image watermarking tools when the target file is a PDF and the watermark is text-based.

Side effects

Watermark text contains non-Windows-1252 characters
Invalid hex color format
Invalid page range specification

Input

Schema · Request body

Field	Type	Description
url	—	Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64.
font	string	Built-in PDF font: helvetica, helvetica-bold (default), times, times-bold, courier or courier-bold.
text	string	Windows-1252 (Latin) text, drawn with a built-in PDF font.
angle	number	Counter-clockwise degrees.
color	string	Text colour as #rrggbb (default #808080, grey).
layer	string	over (default: on top of the page content) or under (behind it; hidden where the page is opaque).
pages	—	Pages to stamp (default all).
margin	number	Points from the edge for non-center positions.
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	0.05 (faint) to 1 (opaque); default 0.3.
position	string	center (default), top-left, top-center, top-right, middle-left, middle-right, bottom-left, bottom-center or bottom-right.
font_size	number	Points (6-300, default 48).
pdf_base64	—	The PDF as base64 (at most 10 MB decoded per request); or use url.
