Common questions.

Quick answers for developers.

Read the docs
How do API-specific SDKs work?
Each API has its own SDK package. For example, to use the Email Validator API, you install @apiverve/email-validator (npm), apiverve-emailvalidator (pip), or APIVerve.EmailValidator (NuGet). This keeps your dependencies lean and provides API-specific typing.
Can I use multiple APIs with one API key?
Yes! Your API key works across all 300+ APIs. Install the SDKs you need and use the same key for all of them — no separate credentials to manage.
What if I prefer REST over SDKs?
All APIs are available via REST with simple GET/POST requests. SDKs are optional but recommended for type safety and convenience. Check the docs for curl examples.
How do I handle rate limits?
Rate limits are based on your plan. Headers include X-RateLimit-Remaining and X-RateLimit-Reset. SDKs handle retry logic automatically with exponential backoff.
Is there a free tier?
Yes! Every account starts with free credits every month. No credit card required to sign up. You can test any API before committing to a paid plan.
How do I get support?
All plans include support. You can reach us via the contact form, join our Discord community, or open a GitHub issue. We typically respond within a few hours during business days.
