Frequently Asked Questions
How does credit pre-settlement work?
Credits are deducted atomically per successful validation. If our system encounters a 500 error or fail-safe timeout, the credit is automatically restored.
Can I reuse requests with Idempotency-Key?
Yes! When you pass an Idempotency-Key header, duplicate validation requests within 24 hours return the cached response without debiting your balance a second time.
What payment methods are supported?
We accept all major credit cards via Stripe, including Visa, MasterCard, American Express, and corporate purchasing cards.
