This project powers the EuroPython 2025 website, Discord bot, and internal bot 🦜 by downloading, transforming, and serving clean, structured JSON files for sessions, speakers, and the schedule, all pulled from Pretalx.

Built for transparency. Designed for reuse. Optimized for EuroPython.

1. Downloads submission and speaker data from Pretalx.
2. Transforms raw data:
   • Removes private/irrelevant fields
   • Normalizes formats
   • Adds computed fields (e.g. URLs, delivery mode)
3. Serves the transformed JSON files via a static API.

1. Clone the repo

   git clone https://github.com/EuroPython/programapi.git
   cd programapi

2. Install uv (fast Python package manager)

3. Create a Python 3.13 virtual environment

   uv venv -p 3.13

4. Install dev dependencies

   make dev

5. Enable pre-commit hooks

   make pre-commit

You can update the event year or shortname in src/config.py.

Also, create a .env file in the project root and set:

PRETALX_TOKEN=your_api_token_here

(Yes, Pretalx has rate limits. Please be nice. 🤪)

• Run the entire pipeline:

  make all

• Run only the download step:

  make download

• Run only the transformation step:

  make transform

• (Optional) Exclude components:

  make all EXCLUDE="schedule youtube"
