`get_credits`Returns the number of verification credits left on the MailProbe account that owns the API key. Reading the balance uses no credit.	Returns the number of verification credits left on the MailProbe account that owns the API key. Reading the balance uses no credit.	Not declared	Yes	Not declared	No
`verify_emails`Checks whether email addresses exist and can receive mail, in real time and without sending anything. Returns one result per address, in input order. Act on `status`: `valid` is safe to send, `invalid` must not be used, `risky` is accepted but uncertain (catch-all domain, role or disposable address, provider that blocks probing) and `unknown` could not be determined. `score` is a 0-100 confidence value, `reason` explains a verdict that is not plainly deliverable and `did_you_mean` suggests a fix for a likely typo. One credit per address actually probed: duplicates and malformed addresses are free. At most 20 addresses per call: split a longer list into several calls.
