## Overview

Add **ZeroBounce** to any ModuleX agent or workflow. Real-time email validation and deliverability checks against the ZeroBounce v2 REST API (`api.zerobounce.net`). Flag invalid, catch-all, spamtrap, abuse, and do-not-mail addresses before outreach, and check the validation credits remaining on your account.

## Limits & Quotas

* **`/validate`**: up to 80,000 requests per 10 seconds per key
  (\~480,000/min).
* **`/getcredits`**: up to 80,000 requests per hour (100,000 for
  ZeroBounce ONE customers) before a temporary block.
* Each `verify_email` call consumes one validation credit.
* **Error model**: ZeroBounce can answer HTTP 200 with an
  `{"error": ...}` envelope (invalid key / out of credits), and
  `getcredits` signals an invalid key with `{"Credits": -1}`. Non-2xx
  responses, error envelopes, and timeouts are caught and returned as
  `success=False` + `error` rather than raising. Plan retries on the
  agent side based on the error string.
