JSON access keys that has are inside array of objects
Question
I'm accessing an API in this link: https://covid19-brazil-api.now.sh/api/report/v1/brazil/20200425/
The last part of this link correspond to data about coronavirus in all of brazil states in a certain date (which is represented by the last part of the link, in this case 04/25/2020)
I want to see information for only one state, but the way the JSON is formatted there is a big array of objects called date, so I can't do this: https://covid19-brazil-api.now.sh/api/report/v1/brazil/20200425/?uf='PE'
This is the JSON:
// 20200428215028
// https://covid19-brazil-api.now.sh/api/report/v1/brazil/20200425/

How should the link be so that the object "data" only shows the objects within it that has "uf"="PE"?

You can't pass a query string to JSON like that. You can, however, use a filter to filter out the data based on key value. It's as simple as this one line:
api.data.filter(a=>a.uf==code);
You can store that in a variable. You can pass it to something else, etc. I made code a variable at the top so you can change it and it will still work. Try for yourself!
var code = "RJ"; const api = { "data": [ { "uid": 35, "uf": "SP", "state": "São Paulo", "cases": 20004, "deaths": 1667, "suspects": 5334, "refuses": 596, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 33, "uf": "RJ", "state": "Rio de Janeiro", "cases": 6828, "deaths": 615, "suspects": 1254, "refuses": 148, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 23, "uf": "CE", "state": "Ceará", "cases": 5421, "deaths": 310, "suspects": 493, "refuses": 89, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 26, "uf": "PE", "state": "Pernambuco", "cases": 4507, "deaths": 381, "suspects": 89, "refuses": 23, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 13, "uf": "AM", "state": "Amazonas", "cases": 3635, "deaths": 287, "suspects": 18, "refuses": 26, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 21, "uf": "MA", "state": "Maranhão", "cases": 2105, "deaths": 100, "suspects": 125, "refuses": 13, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 29, "uf": "BA", "state": "Bahia", "cases": 2081, "deaths": 70, "suspects": 573, "refuses": 36, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 32, "uf": "ES", "state": "Espírito Santo", "cases": 1595, "deaths": 47, "suspects": 71, "refuses": 21, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 15, "uf": "PA", "state": "Pará", "cases": 1579, "deaths": 86, "suspects": 43, "refuses": 23, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 31, "uf": "MG", "state": "Minas Gerais", "cases": 1481, "deaths": 58, "suspects": 925, "refuses": 104, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 42, "uf": "SC", "state": "Santa Catarina", "cases": 1209, "deaths": 42, "suspects": 346, "refuses": 47, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 41, "uf": "PR", "state": "Paraná", "cases": 1140, "deaths": 69, "suspects": 400, "refuses": 119, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 43, "uf": "RS", "state": "Rio Grande do Sul", "cases": 1096, "deaths": 34, "suspects": 416, "refuses": 330, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 53, "uf": "DF", "state": "Distrito Federal", "cases": 1013, "deaths": 26, "suspects": 327, "refuses": 107, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 24, "uf": "RN", "state": "Rio Grande do Norte", "cases": 781, "deaths": 40, "suspects": 108, "refuses": 22, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 16, "uf": "AP", "state": "Amapá", "cases": 685, "deaths": 19, "suspects": 15, "refuses": 0, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 52, "uf": "GO", "state": "Goiás", "cases": 506, "deaths": 25, "suspects": 353, "refuses": 55, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 27, "uf": "AL", "state": "Alagoas", "cases": 501, "deaths": 29, "suspects": 43, "refuses": 22, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 25, "uf": "PB", "state": "Paraíba", "cases": 447, "deaths": 46, "suspects": 85, "refuses": 11, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 14, "uf": "RR", "state": "Roraima", "cases": 345, "deaths": 3, "suspects": 9, "refuses": 0, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 11, "uf": "RO", "state": "Rondônia", "cases": 328, "deaths": 7, "suspects": 61, "refuses": 2, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 22, "uf": "PI", "state": "Piauí", "cases": 297, "deaths": 17, "suspects": 12, "refuses": 2, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 12, "uf": "AC", "state": "Acre", "cases": 258, "deaths": 11, "suspects": 12, "refuses": 0, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 51, "uf": "MT", "state": "Mato Grosso", "cases": 247, "deaths": 9, "suspects": 45, "refuses": 8, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 50, "uf": "MS", "state": "Mato Grosso do Sul", "cases": 217, "deaths": 7, "suspects": 93, "refuses": 26, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 28, "uf": "SE", "state": "Sergipe", "cases": 153, "deaths": 9, "suspects": 15, "refuses": 11, "datetime": "2020-04-25T20:34:01.065Z" }, { "uid": 17, "uf": "TO", "state": "Tocantins", "cases": 50, "deaths": 2, "suspects": 13, "refuses": 0, "datetime": "2020-04-25T20:34:01.065Z" } ] }; var filtered = api.data.filter(a=>a.uf==code); console.log(filtered);
