post/ebay/v1/sold_search2 credits

⭐SOLD/completed search by `query` (LH_Sold=1&LH_Complete=1, bare, NOT login-gated) -> results[]{...,sold_price{value,currency},sold_date} + price_stats{count,min,max,avg,median,stdDev,p10/p25/p75/p90,recommendedPrice(IQR-trimmed),outliers_removed,per_condition{bucket:{count,median,avg,min,max}},velocity{sales_per_day,days_to_sell,recent_sales_per_day,sales_last_7d/30d,span_days},trend{direction,slope_per_day,pct_change}} — ALL derived from the sold-array+sold_date, NO extra fetch (AI-free comps math). Same filters as search. The price-research moat.

Working example
Parameters

eBay category ID to narrow results — the number in an eBay category URL (e.g. 9355 = Cell Phones & Smartphones). Leave empty for all categories.

Which eBay site to query (sets currency and local listings). Dropdown = the 13 live-verified sites; other eBay country sites (e.g. com.sg, com.hk) are also accepted.

Page number (easy paging: 1, 2, 3…). (1–)

How many results to return (1–240 per page; larger values are capped at 240). (1–240)
