Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

reoon
reoon_account_balance
Read remaining daily and instant Reoon credits without verifying an email.
reoon_bulk_results
Read a previously created bulk task, its progress, and a bounded page of completed email results. Does not start new verification. Wait between polls. Very large upstream exports must be downloaded in the Reoon dashboard.
reoon_create_bulk_verification
Submit 10–1,000 emails for asynchronous POWER verification. Starts a vendor job and can spend verification credits. Requires confirm:true; the job may continue if the response is lost. Check the dashboard before resubmitting. Results are later read with reoon_bulk_results.
reoon_verify_email
Check email syntax, domain/MX and disposable-address signals in QUICK mode. Does NOT verify inbox existence or guarantee delivery. Can spend Reoon credits; confirm:true is required. Do not run continuously in more than five parallel requests. Use bulk verification for lists.
