id (request identifier), took_ms (processing time), and request (normalized parameters and defaults).
The account endpoint returns fields directly. Errors use an error object.
Start at
page=1, preserve your parameters, and follow next_page until it is null. Each page costs one request. Page sizes are fixed; limit, page_size, and offset are unsupported. See each endpoint for page limits.
Flights, return options, and product search always have next_page: null and reject page. Other non-list endpoints are unpaginated. Positions start at 1 per page; deduplicate items when combining changing live results.
Only rely on required fields in the API reference. Optional data and result IDs can be absent. Empty results is successful and consumes quota.
Pass opaque result IDs unchanged to matching follow-up endpoints, only when present. Flight follow-ups also require the original route and dates.
