To verify if a Kratos account is valid using an API with just a login and password, without maintaining an active session, you can use the login flow API. Here's how you can do it: 1. Initiate a login flow for API clients using the

/self-service/login/api

endpoint. 2. Complete the login flow by submitting the credentials to the action URL returned in the first step. 3. Check the response for a successful login. Here's a step-by-step example using curl:

bash # Initiate a Login Flow actionUrl=$(   curl -s -X GET -H "Accept: application/json" \     "<https://playground.projects.oryapis.com/self-service/login/api>" \     | jq -r '.ui.action' )  # Complete Login Flow with password method curl -s -X POST -H "Accept: application/json" -H "Content-Type: application/json" \     -d '{"identifier": "<mailto:user@example.com|user@example.com>", "password": "yourpassword", "method": "password"}' \     "$actionUrl" | jq

If the login is successful, you'll receive a JSON response containing the session information [Ory Docs - Login API](https://www.ory.sh/docs/kratos/self-service/flows/user-login#api-clients). You can check for the presence of a

session_token

in the response to verify if the login was successful. Note that this method will create a session token, but you don't need to use or store it if you just want to verify the account. Simply checking for a successful response is enough to confirm that the credentials are valid. Remember to replace

"<mailto:user@example.com|user@example.com>"

and

"yourpassword"

with the actual credentials you want to verify. This approach allows you to verify the account without maintaining an active session, as requested.
