MassivePix

Industry-standard OCR API to convert PDFs and images into clean Markdown — with full support for math equations, tables, and structured formatting.

Features

• Convert PDF files to well-formatted Markdown
• Preserves LaTeX math notation ($\delta(x)$, integrals, etc.)
• Handles tables, lists, headings, and complex layouts
• Simple REST API via Bibcit
• Chain with the MassiveMark API to further convert Markdown to HTML, DOCX, or RAG-optimized PDF

Quick Start

Prerequisites

• A Bibcit API key — get one at bibcit.com

Python

pip install requests

import requests

pdf_file_path = "input.pdf"

with open(pdf_file_path, "rb") as f:
    files = {"file": (pdf_file_path, f)}
    headers = {
        "Bibcit-Key": "YOUR_API_KEY",
    }
    response = requests.post(
        "https://api.bibcit.com/api/massivepix/ftom",
        headers=headers,
        files=files,
    )

with open("output.md", "w", encoding="utf-8") as f:
    f.write(response.text)

JavaScript (Node.js)

import fs from 'fs';

const formdata = new FormData();
const pdfFilePath = 'input.pdf';
const pdfContent = new Blob([fs.readFileSync(pdfFilePath)]);
formdata.append("file", pdfContent, pdfFilePath);

const response = await fetch('https://api.bibcit.com/api/massivepix/ftom', {
    method: "POST",
    headers: {
        'Bibcit-Key': 'YOUR_API_KEY',
    },
    body: formdata,
