Our search endpoint offers a flexible and powerful way to find specific companies. This guide explains the various filtering options available.

​
Basic Structure

The core of the filtering mechanism is the filters array in the request body. Each object in this array represents a single filter condition and must contain a field and a corresponding value using one of the available filter types. 
{
  "filters": [
    {
      "field": "status",
      "value": "active"
    }
  ]
}

​
Free-Text Search Query

Besides structured filters, you can also perform a free-text search using the query field. This is useful for finding companies by name or previous names. 
{
  "query": {
    "value": "Descartes"
  },
  "filters": [
    {
      "field": "city",
      "value": "Berlin"
    }
  ]
}
This will search for companies with “Descartes” in their name or previous names and are located in Berlin.

​

Filter Types

There are several ways to specify the filter value, depending on the desired comparison.

​
Exact Match: value

For a simple exact match, use the value property. 
{
  "field": "legal_form",
  "value": "gmbh"
}

​
Multiple Values: values

To match against a list of possible values, use the values array. This is useful for “OR” conditions. 
{
  "field": "city",
  "values": ["Berlin", "Hamburg", "München"]
}

​
Keyword Matching: keywords

For text fields, keywords allows you to find records containing any of the specified words. 
{
  "field": "zip",
  "keywords": ["10117", "10119"]
}

​
Range Filtering: min and max

For numerical and date fields, you can specify a range using min and max. 
{
  "field": "employees",
  "min": "10",
  "max": "100"
}
You can also specify just a minimum or a maximum. 
{
  "field": "revenue",
  "min": "1000000"
}

​
Date Formatting

When filtering by date, use the DD-MM-YYYY format. 
{
  "field": "incorporated_at",
  "min": "01-01-2020",
  "max": "31-12-2021"
}

​
Location Filtering

You can also filter companies based on their geographical location by providing a location object in the request body. This allows you to find companies within a certain radius of a given point. The location object requires latitude and longitude, and optionally accepts a radius in kilometers. 
{
  "location": {
    "latitude": 52.5200,
    "longitude": 13.4050,
    "radius": 10
  }
}

​
Combining Filters

You can combine multiple filter objects in the filters array. These conditions are joined with an “AND” operator, meaning a company must satisfy all of them to be included in the results. 
{
  "filters": [
    {
      "field": "legal_form",
      "value": "gmbh"
    },
    {
      "field": "employees",
      "min": "50"
    }
  ]
}
