Frequently Asked Questions

We support full transliteration for 25+ scripts including Arabic, Cyrillic, Greek, Hebrew and CJK. Need another language? Contact us.

Yes. Every request, even those resulting in errors, consumes credits. This is because your credits are strictly tied to the number of requests, regardless of success or failure. However, if the error is clearly due to a platform problem on our end, we’ll recover those credits for you.

Contact us at [email protected]. We take feedback seriously—if your bug report or feature request is meaningful, we can fix or improve the API quickly and grant you 50 free credits as a thank you.

It depends on the API and sometimes even on the endpoint. Some endpoints use data from external sources, which may have stricter limits. We also enforce limits to prevent abuse and keep our platform stable. Check the docs for the specific rate limit for each endpoint.

We operate on a credit system. Buy once—credits never expire. They’re non-refundable units for making API calls (requests). Simple, fair, and you top up only when you need more.

Every HTTP call is one request. Each request consumes a number of credits depending on the endpoint. In most cases, you can make thousands of requests with just one credit—but always check each endpoint for its cost.

Yes. Your credits never expire until you use them, but they are non-refundable.

Credits are non-refundable. Only buy what you need—you can always top-up later. If we screw up and it costs you, we’ll fix it.

Prices are set in credits, not dollars. Each endpoint lists its own cost—see the “Credits / request” badge above. You’ll always know exactly what you’re spending.
