Markdown Converter

Build an API for converting any document to markdown

Build a production API that accepts any document format and returns clean, structured markdown. An agent handles format detection, conversion strategy, and quality assurance — while the API manages file handling, queuing, and delivery.

Implementation

  1. 1

    Design the API

    Define endpoints for synchronous conversion (small files) and async conversion (large files). Support file upload and URL input.

  2. 2

    Build the format router

    Create an agent that detects input format and routes to the optimal conversion pipeline — PDF, DOCX, HTML, images, spreadsheets, etc.

  3. 3

    Implement conversion pipelines

    Build specialized conversion agents for each format. Each agent handles the unique challenges of its format while producing consistent markdown output.

  4. 4

    Add quality scoring

    Every conversion response includes a confidence score. Flag low-confidence conversions for review and provide detailed quality metrics.

  5. 5

    Deploy with rate limiting

    Set up file size limits, rate limiting, concurrent processing limits, and webhook notifications for async jobs. Monitor conversion quality metrics.

What You Get

  • One API endpoint for any document format to markdown
  • Quality scoring on every conversion
  • Async processing for large files with webhook notifications
  • Production-ready with rate limiting and monitoring
