FastAPI Routes

Concept

FastAPI turns Python functions into HTTP endpoints. Decorate a function with @app.get("/path") or @app.post("/path") and it becomes an API route. The function's return value becomes the HTTP response.
m3shdup/app/main.py 
from fastapi import FastAPI

app = FastAPI()

@app.get("/api/health")
async def health():
    return {"status": "ok", "version": "1.0"}

# When someone visits https://commander.gritwerk.com/api/health
# they get: {"status": "ok", "version": "1.0"}

What's happening

The @app.get line is a decorator — it registers the function as a handler for GET requests to that URL path. FastAPI automatically converts the returned dict to JSON. This is exactly how your mesh health check works.

Quick Check — 3 questions

1. What does @app.get("/api/health") do?

2. What format does FastAPI use when you return a dict?

3. What's the difference between @app.get and @app.post?
