Frequently Asked Questions

Quick answers regarding integration requirements and API architecture.

How fast are the search responses?
Our gateway executes concurrent searches across airline feeds with asynchronous parallel dispatch, delivering unified JSON results within 1.2 to 2.5 seconds on average.
How do bookings and ticketing work?
You can place seats on hold to obtain an official airline PNR with a Ticketing Time Limit (TTL). Tickets are issued seamlessly against your pre-funded B2B agency wallet balance.
What are the rate limits?
Default tier allows up to 60 search requests per minute and 30 booking/reprice actions per minute. High-volume enterprise limits are available upon commercial review.
Is sandbox testing free?
Yes. Sandbox keys are provided with complete simulated booking and live search capabilities without deducting any real agency balance.
