find_emails
Bulk-find business emails for a LIST of contacts (name + company domain each). Submits the list, waits for completion, and returns the found email per contact. Up to 1000 contacts. Charges 10 Fox Credits per contact. Large lists that don't finish quickly return a jobId to poll with get_job.
get_credits
Get the current Fox Credit balance for the Verifox account tied to the API key. Free — no credits charged. Use it to check remaining balance before a big verify/find run (verify = 1 credit/email, find = 10 credits/contact).
get_job
Check an async job started by verify_emails, find_email, or find_emails. Returns results if finished, otherwise the current status. Use the type shown in the submitting tool's response.
