It is just a sample API response. Some objects will have more attributes. New arrays will also be there.
Understanding the Response
In the JSON response, you may observe that many objects include references (IDs or codes) to objects from other lists. This pattern is employed in our API to prevent redundant data and reduce the overall size by allowing multiple objects to reference the same data.
itineraries
A return trip will consist of 2 legs, while a one-way trip will consist of 1 leg. An itinerary will contain a deepLink field which takes the traveler to the booking page.
legs
Provides information about the flight leg from the destination to the origin. A leg comprises a single segment for a direct flight and may consist of multiple segments if there are several stopovers.
segments
Displays information about individual stops within a leg. For instance, if a leg includes one-stop, the segment will provide details about the stopover, including its duration and location.
places
Reveals specific stops within a leg. For instance, in the case of a leg with a single stop, the segment will present information about the stopover, including its duration and location.
carriers
Like places, the carriers section contains details about the airlines mentioned in the itineraries.
agents
Just like places, the agents section comprises details about the Online Travel Agencies (OTAs) mentioned in the itineraries.
Sometimes you might have to make more than one API call to get complete data. Since we compare a lot of airlines and vendors sometimes it becomes impossible to pull this much amount of data at once
