Convert JSON to YAML

curl -s -X POST http://localhost:8008/v1/convert \
  -H "Content-Type: application/json" \
  -d '{"content": "{\"name\": \"Alice\", \"age\": 30}", "input_format": "json", "output_format": "yaml"}' | jq -r '.result'

Convert YAML to JSON

echo "name: Alice" | curl -s -X POST http://localhost:8008/v1/convert \
  -H "Content-Type: application/json" \
  -d "{\"content\": $(cat - | jq -Rs), \"input_format\": \"yaml\", \"output_format\": \"json\"}" | jq -r '.result'
