QPX Express API Alternative

Google QPX Express is not available anymore. Google shut down QPX Express on April 10, 2018 and ended new registrations before the shutdown. If you found old QPX code or blog posts, there is no public QPX Express key to revive.

There was no one-for-one public Google replacement. Teams moved to enterprise travel contracts, affiliate programs, ticketing platforms, or scraping. Ignav fits the simpler use case: search live fares and send users to booking pages.

What QPX Express users were building

The common QPX shape was straightforward: origin, destination, travel date, passengers, cabin, and filters in; priced flight options out. That maps to products like flight search pages, fare comparison tools, price alerts, internal travel tools, and route research scripts.

Replacing the fare-search flow

With Ignav, one-way and round-trip searches are normal POST requests. Results are structured itineraries with prices, legs, segments, baggage fields, and an opaque ignav_id. When a user chooses an itinerary, send that ID to POST /api/fares/booking-links to fetch airline and OTA booking URLs.

Pricing is also intentionally plain: 1,000 free requests, then $2.00 per 1,000 successful requests. Failed requests are never billed. There are no monthly minimums and no per-account rate limits for authenticated API use.

What Ignav does not replace

Ignav is not QPX Enterprise, a GDS contract, or a booking platform. It does not issue tickets, collect traveler payments, manage PNRs, handle cancellations, or sell ancillaries. If you need the full booking and servicing lifecycle, look at ticketing/order-management APIs instead.
