#### Check the `openapi.json` { #check-the-openapi-json }

If you are curious about how the raw OpenAPI schema looks like, FastAPI automatically generates a JSON (schema) with the descriptions of all your API.

You can see it directly at: <a href="http://127.0.0.1:8000/openapi.json" class="external-link" target="_blank">http://127.0.0.1:8000/openapi.json</a>.

It will show a JSON starting with something like:

```JSON
{
    "openapi": "3.1.0",

func (db *DB) Save(value interface{}) (tx *DB) {
	tx = db.getInstance()
	tx.Statement.Dest = value

	reflectValue := reflect.Indirect(reflect.ValueOf(value))
	for reflectValue.Kind() == reflect.Ptr || reflectValue.Kind() == reflect.Interface {
		reflectValue = reflect.Indirect(reflectValue)
	}

	switch reflectValue.Kind() {
	case reflect.Slice, reflect.Array:
		if _, ok := tx.Statement.Clauses["ON CONFLICT"]; !ok {
