PDF Engine

The PDF
processing API.

The core PDF operations — generate, merge, split, compress, OCR, watermark, secure — as REST endpoints and MCP tools, behind one API key. The foundation the rest of the platform is built on.

And there’s more — every endpoint, as both a REST call and an MCP tool, lives in the docs.

For most APIs, the file
is the finish line.

For us, it’s the starting line. One POST /docs and the PDF you just made enters the tracking platform.

Others

A file.
Then nothing.

Generate it, reshape it, OCR it — then they hand you bytes and wave goodbye.

The same operation over plain REST, in your language, or as an MCP tool an agent calls itself.
