]Name
This attribute shows a human-friendly label. Only by reading the Json above you now that, for example, this is a classified category that doesn’t allow to include shipping options, there are 1332 items listed under it, and you can include the price on ARS or USD.
Mandatory attributes
Mandatory attributes are set as “required” under the category detail. On the example above you can see that price and stock are required, coverage areas are not allowed and seller_contact is optional. Also specific category attributes like attributes like “Antigüedad” and “Estado” that has the tag “required”: true, need to be sent with the possible values detailed on the Json.
Category Dump
The category tree does not change very often. If you prefer, you can request a dump of the whole category tree for a given country site for offline processing. This API returns the category tree in JSON format within a gzip-encoded response.
To get the categories for Brazil, use this URL:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLB/categories/allTo get the categories for Argentina, use this URL:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/categories/allThis URL contains 2 headers that can be used to check when the last dump was generated.
- X-Content-Created: contains the date of the last generation.
- X-Content-MD5: contains the MD5 checksum of the last generation.
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/categories/allHTTP/1.1 200 OK

Choose category for your property
Choosing the right category for your real estate property will determine how quickly buyers will find your item and will improve your chances of selling it. For this reason, we highly recommend to use our Category predictor tool before listing an item.
Search by category
The search operation returns items which belong to a MercadoLibre item category, there can be tons of items under certains categories but don’t worry, you can paginate results, read about paging search results. To get every item under a given category, do as it follows:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/search?category=MLA5726The search response has a lot of parameters. Use OPTIONS http method to get a JSON encoded response that will describe the API, with all the allowed methods and connections between another part of the API.
Paging & sizing results
This tutorial will come handy for you from now on because it will help you to work with specific set of results each time you make an API call. Most resources have common url parameters to paginate and size results, which are: Limit and Offset.
Default values
Default values are offset=0 and limit=50.
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/search?q=ipod nanoIn the paging section of the JSON response, you can see the total number of items that match the search and the offset value with the default limit applied.
"paging": {
"total": 285,
"offset": 0,
"limit": 50,
}
...Limit
To reduce the page size you can change the limit parameter. For example, if you are interested in retrieving just the first 3 items:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/search?q=ipod nano&limit=3This action retrieves a JSON data with an array of 3 items as shown:
{
"site_id": "MLA",
"query": "ipod nano",
"paging": {
"total": 284,
"offset": 0,
"limit": 3,
},
"results": [
{...},
{...},
{...},
],
"sort": {...},
"available_sorts": [...],
"filters": [...],
"available_filters": [...],
}
Offset
By using the offset attribute, you can move the lower limit of the result block. For example, if you are interested in retrieving the 50 items that follow the default response.
Example:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/search?q=ipod nano&offset=50Response:
{
"site_id": "MLA",
"query": "ipod nano",
"paging": {
"total": 285,
"offset": 50,
"limit": 50,
},
"results": [...],
"sort": {...},
"available_sorts": [...],
"filters": [...],
"available_filters": [...],
}This response retrieves 50 items starting from the first fifty items.
Define a range of results
It is possible to combine both parameters. You can retrieve items from the third to the sixth item in the original search result:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/sites/MLA/search?q=ipod nano&offset=3&limit=3This action retrieves a JSON data with an array of 5 items as shown:
{
"site_id": "MLA",
"query": "ipod nano",
"paging": {
"total": 285,
"offset": 3,
"limit": 3,
},
"results": [
{...},
{...},
{...},
],
"sort": {...},
"available_sorts": [...],
"filters": [...],
"available_filters": [...],
}
