GET|POST /v1/ebay/search
```

**Price** $0.001 per call. [List price](https://apinoa.com/en/pricing); the rate steps down above 1,000 calls a day.

| Parameter | Type | Required | Notes |
|---|---|---|---|
| `query` | string | yes | Keywords to search for. Required here: eBay's keyword search cannot be asked anything without words — to list a category with no keyword, use `browse`. |
| `brands` | string list |  | Brand names as the marketplace spells them, e.g. brands=Nike,Adidas. |
| `categoryId` | string |  | Narrow to one category, by the marketplace's own id. Opaque and per-marketplace; take it from Product.category[].id or from a result's `facets`. |
| `condition` | enum |  | Item condition. `new` `used` `refurbished` |
| `facets` | string \| object list |  | Narrowings taken from a result's `facets`, e.g. facets=Color:Black. The escape hatch for filters the typed vocabulary has no word for; prefer a typed parameter where one exists. |
| `freeShipping` | boolean \| enum |  | Only listings the marketplace itself advertises as shipping free. |
| `page` | integer |  | 1-based page number. eBay pages by number, so there is no `cursor`; each page is charged separately. |
| `pageSize` | integer |  | Results per page: 60, 120 or 240 only, the three page sizes eBay offers. Larger pages take longer to return (about 5 s for 240 items), but a page of any size costs one call. |
| `priceMax` | number ≥ 0 |  | Highest price to return, in decimal major units. |
| `priceMin` | number ≥ 0 |  | Lowest price to return, in decimal major units. |
| `region` | string |  | Buyer country as ISO 3166-1 alpha-2; sets availability, shipping and price. |
| `sort` | enum |  | Result ordering. `price_asc`/`price_desc` are eBay's price-plus-shipping sorts rather than its bare-price ones, and `ending_soonest` orders by auction close. `best_match` `ending_soonest` `newly_listed` `price_asc` `price_desc` |

```bash
curl "https://gateway.apinoa.com/v1/ebay/search?query=running+shoes&brands=Nike&condition=new&freeShipping=true&sort=price_asc" \
  -H "x-api-key: YOUR_API_KEY"
```

**`pageSize` 会在服务端归入三档**（25/50/60 → 60，100/120 → 120，200/240 → 240），因此只接受这三个值；
接受其他值就等于收下它再忽略它。

更大的页数耗时更长（240 条约 5 秒），但仍只计一次调用。

**没有 `cursor`**——翻页按页码进行。**没有 `ratingMin`**——eBay 的结果不提供评分筛选。**没有 `inStock`**
——买不到的商品本来就不会被列出。

**没有 `currency`。** 币种随 `region` 而定。接受一个我们无法兑现的币种，比直接拒绝更糟。
