🍕 SLOpPy - SLO demonstration on a simple Python API, that will design pizza toppings based on Wikipedia articles

🍕 What it does

This small API developed in FastAPI framework is using Spacy NLP to analyse Wikipedia articles & create pizza ideas based on the extracted words. The code is instrumented for Prometheus metrics scraping and should serve as an example of how to use Service Level Objectives to understand how well the API is performing The stack comes with Prometheus and Grafana so you can directly observe the outputs.

🍕 Why?

There's never enough pizza toppings and there's never enough of clear understanding of how SLOs work

🍕 Endpoints and params

All endpoints use GET method and simple request params.
