Connect your FairValid workspace to verify email addresses you are authorized to process. Submit one address or batches of up to 5,000, follow asynchronous jobs, read paginated results, cancel remaining work, and check available and held credits. Sign in through FairValid OAuth and select a live API key with the required permissions and spending cap. Live submissions may reserve credits. Completed Valid and Invalid checks use one credit each; genuine Unknown and unresolved catch-all outcomes have no net verification charge. A Valid result is not a guarantee of inbox delivery. The integration does not send email or buy credits. Direct Test-key fixtures are a separate sandbox mode; OAuth uses live keys.
