The data can be queried programmatically through our API. Feel free to experiment the current features and report your user experience through our Feedback system. The awesome Socrata API has been inspiring our design, so that there's an almost total compatibility between the two. Stay tuned - more functionality is on its way!
Format | Description |
---|---|
json | An array that contains N members according to the number of results retrieved by the query. In the response header you can find some useful information about itself, for example the number of results (X-DL-Count) and the dataset version (X-DL-datagem-version). Each member is a JSON object containing all key-values pairs corresponding to all columns present in the datagem |
api | Pretty interface for using the API, the full response, comprehensive of headers, is displayed in a dedicated styled page |
Some datagem fields contain more than one value. For example in the Places datagem the municipality field contains both the name and the acheneID of the municipality. We call these fields composites. "municipality" is the composite root, while "name" and "acheneID" are called composite fields.
You can access composite fields using dot notation: in the above example, you can filter on "municipality.name" and "municipality.acheneID" (but not on "municipality" itself).
In $select, you can get the whole composite using the composite root, or just a field using dot notation.
Code range | Description |
---|---|
200 - 299 | The request was successful |
400 - 499 | The request failed because there was something wrong with the request |
500 - 599 | The request failed because there is a problem on the server. Our fault! |
All 4xx error codes are associated with a JSON response, that contains:
Parameter | Description |
---|---|
message | a specific error message, that suggests the cause of the error |
code | the internal error code that the API return |
data | object with additional error information |
error | "true" |
The V1 API have no specified requests limit. You are nonetheless invited to throttle your requests so that the service remains responsive for everyone. Anyway there’s a limit on the number of maximum elements that an API response can return, currently set to 100000. Please use pagination if you need to retrieve more elements.
