        "longDescription": "Connect your FairValid workspace to verify email addresses you are authorized to check. Submit batches of up to 5,000 addresses, track asynchronous jobs, read paginated results, cancel remaining work, and inspect available and held credits. Sign in through FairValid and select a live API key with the required permissions. OAuth connections perform live work; sandbox fixtures require a separate direct test-key connection. Before submitting or cancelling work, the plugin asks for confirmation of the action and its effect on workspace credits. It preserves idempotency keys after uncertain responses and reports pending work as pending. Unknown and unresolved catch-all results are not proof of validity. A valid result is not an inbox-delivery guarantee. The plugin does not send email or access other workspaces.",
