Testing with cURL

You can test these examples using cURL:

curl -X POST http://localhost:8080/submit \
  -H "Content-Type: application/json" \
  -d '{
    "language": "python",
    "code": "name = input(\"Enter your name: \")\nprint(f\"Hello, {name}!\")\nfor i in range(5):\n    print(f\"Count: {i}\")",
    "input": "World"
  }'

This will return a submission ID:

{
  "id": "6423259c-ee14-c5aa-1c90-d5e989f92aa1"
}

You can then check the status and result:

curl http://localhost:8080/status?id=6423259c-ee14-c5aa-1c90-d5e989f92aa1

curl http://localhost:8080/result?id=6423259c-ee14-c5aa-1c90-d5e989f92aa1
