}Frequently Asked Questions
Is the free plan actually free — no hidden charges?
Yes. The Starter plan is completely free with no credit card required, no trial period, and no auto-upgrade. You get 200 validations per month indefinitely until you choose to upgrade.
What happens when I exceed 200 validations on the free plan?
API calls beyond your monthly quota will return a 429 Too Many Requests response with a quota exceeded message. You can upgrade to the Growth plan at any time to unlock 100,000 validations per month.
Does the free plan include SMTP verification?
Yes. All ValidoAPI features including SMTP verification, disposable detection, catch-all checking, and deliverability scoring are included in the free Starter plan.
Can I use the free plan in a production application?
Yes. The free plan is fully production-ready. The only limitation is the 200 monthly quota and 10 requests/second rate limit. If your production volume exceeds this, upgrade to Growth.
Does ValidoAPI have a free trial for paid plans?
Yes. The Growth plan comes with a 7-day free trial in addition to the permanent free Starter plan. This lets you test higher volume before committing to a paid subscription.
