Output of the simplest request in your browser

To see the results of the simple request from the previous page, open follow this link. The results will look like this:

{
  "responseHeader":{
    "status":0,
    "QTime":0,
    "params":{
      "q":"*:*",
      "fl":"marker_symbol,effect_size,p_value",
      "rows":"3"}},
  "response":{"numFound":5197637,"start":0,"docs":[
      {
        "effect_size":0.0,
        "marker_symbol":"Sarnp",
        "p_value":1.0},
      {
        "marker_symbol":"Klhdc2"},
      {
        "effect_size":0.697501747030049,
        "marker_symbol":"Uap1",
        "p_value":6.96763811835258E-10}]
  }
}

The output is a JSON file. Each object in curly brackets is a key:value pair. We have two sections:

• The responseHeader section provides metadata about the query response, such as status, query time, and query parameters.
• The response section contains the data retrieved from the database, including the number of documents found.

Instead of constructing the query manually in the browser as we did here, next we will use the Python package impc_api.
