Firebase REST API login verification format error?

I am using Firebase Email authentication REST API to login to my app.

I want to know if the email is verified or not.

I referred https://firebase.google.com/docs/reference/rest/auth#section-confirm-email-verification

I got the rest URL https://identitytoolkit.googleapis.com/v1/accounts:update?key=[API_KEY]

the given URL also take a payload as oobCode , the output of post request should be a JSON object with a field emailVerified.

now my main goal is to know emailVerified boolean field, the given REST URL does not take any other information like whose email to check if it is verified or what is his access_token, I don't want to provide addition VERIFICATION_CODE as I sent a verification link, not the code.

Is there a very to know if the given URL is verified or not with REST API??

thank you.
