You can check the syntax of your OPL (Ory Permission Language) file for Keto by using the

checkOplSyntax

API endpoint. Here's how you can do it: 1. Send a

POST

request to the

/opl/syntax/check

endpoint. The OPL file content should be included in the body of the request.

json POST /opl/syntax/check Body:  {   'content': {     'text/plain': {       'schema': {         'description': 'Your OPL content here',         'type': 'string'       }     }   },   'x-originalParamName': 'Body' }

2. The response will be a

CheckOPLSyntaxResponse

object. If there are any syntax errors in your OPL file, they will be listed in the

errors

property of the response. Please note that this operation does not require authentication. For more details, you can refer to the [Ory Keto API documentation](https://www.ory.sh/docs/keto/reference/rest-api).

Yes, you can use the Ory Keto CLI to start a server that serves the HTTP REST and gRPC APIs. You can do this using the

keto serve

command. This command opens the network ports and listens to HTTP and gRPC API requests. Here's how you can do it:

bash keto serve

Once the server is running, you can then send your

POST

request to the

/opl/syntax/check

endpoint to check the syntax of your OPL file. For more details, you can refer to the [Ory Keto CLI documentation](https://www.ory.sh/docs/keto/cli/keto-serve#keto-serve).
