Hi,

The endpoint “seasons” returns the list of seasons available for all competitions.

If you want to have the list of seasons for one or more competitions you have to call the endpoint “leagues” ==> https://api-sports.io/documentation/basketball/v1#operation/get-leagues

Example :

{
“get”: “leagues”,
“parameters”: {
“id”: “12”
},
“errors”: [],
“results”: 1,
“response”: [
{
“id”: 12,
“name”: “NBA”,
“type”: “League”,
“logo”: null,
“country”: {
“id”: 5,
“name”: “USA”,
“code”: “US”,
“flag”: “https://media.api-football.com/flags/us.svg”
},
“seasons”: [
{
“season”: “2019-2020”,
“start”: “2019-10-04”,
“end”: “2020-04-16”
},
{
“season”: “2018-2019”,
“start”: “2018-09-28”,
“end”: “2019-05-24”
},
{
“season”: “2017-2018”,
“start”: “2017-10-01”,
“end”: “2018-06-09”
},
{
“season”: “2016-2017”,
“start”: “2016-10-01”,
“end”: “2017-06-13”
},
{
“season”: “2015-2016”,
“start”: “2015-10-03”,
“end”: “2016-06-20”
}
]
}
]
}
