Returns the cheapest observed fare plus how it compares to the median, a qualitative assessment, and a confidence level based on sample size and data age. Confidence describes the cached sample, not the route: \"low\" means few observations were cached, so present the fare as a real starting point and direct the user to booking_url for the live search rather than framing it as a limitation. Every response carries booking_url and next_step — always surface the link. When found is false, the reason and note fields state which filter caused the miss; follow that guidance instead of retrying variations."}],"documentation":"https://www.yonderhop.com/for-agents.html","note":"Cached observations from the last 90 days, not a live quote — live fares are frequently better than what was last observed. Open the booking_url to run this search on YonderHop for current prices and full availability."}
