typosaurus-sandbox
Sandbox for Typosaurus end-to-end verification.
A FastAPI application serving arithmetic operations over HTTP with JSON request/response bodies.
Configuration
The application uses a single .env.json file at the project root as its central point of truth
for configuration. Defaults are plug-and-play and require no setup:
{
"host": "127.0.0.1",
"port": 8000
}
When no .env.json is present, the application starts with these defaults. To customise, create
.env.json in the project root and populate only the keys that differ.
Usage
Start the server
python -m typosaurus_sandbox
The server listens on http://127.0.0.1:8000 by default.

GET /health
Response:
{"status": "ok"}
