API documentation
Reach the portal's datasets straight over HTTP, without downloading a file. No authentication is required; every endpoint offers public read access.
Base address
https://ckan.buyukverianalitigi.com/api/3/action/Every response is UTF-8 JSON and uses the same envelope:
{
"success": true,
"result": { ... }
}On failure "success" is false and an "error" object is returned. The HTTP status code may differ from 200.
Querying data - datastore_search
Used to query the rows of a dataset. Only resources loaded into the DataStore can be queried; the datasets reachable through the API are listed below.
GET https://ckan.buyukverianalitigi.com/api/3/action/datastore_search?resource_id=<kaynak-id>Parameters
| Parameter | Description |
|---|---|
resource_id | Required. Id of the resource to query. |
limit | Number of rows to return (default 100). |
offset | Number of rows to skip. Together with limit it provides pagination. |
sort | Ordering: field name and direction, e.g. yil desc. Several fields can be given, comma separated. |
filters | Per-field equality filter; a JSON object, e.g. {"yil":"2025"}. |
q | Full-text search. Either a single string or a per-field JSON object. |
fields | Returns only the listed fields (comma separated). |
distinct | When true, duplicate rows are collapsed into one. |
SQL querying (datastore_search_sql) is disabled on this deployment; filter and sort with the parameters above.
Downloading all the data
To take a whole resource without paging, use the dump endpoints:
GET https://ckan.buyukverianalitigi.com/datastore/dump/<kaynak-id>?format=csv
GET https://ckan.buyukverianalitigi.com/datastore/dump/<kaynak-id>?format=json
GET https://ckan.buyukverianalitigi.com/datastore/dump/<kaynak-id>?format=xml
GET https://ckan.buyukverianalitigi.com/datastore/dump-xlsx/<kaynak-id>The XLSX endpoint is specific to this portal; the other three are the DataStore's standard output.
Usage limits
| Authentication | Not needed. No API key or membership is required. |
|---|---|
| Permitted operations | Read only. Creating, updating and deleting data is closed from outside the portal. |
| Request limit | 60 requests per minute on the query endpoints and 6 per minute on the bulk download endpoints, per IP. There is no daily quota; the limit exists to protect system resources. |
| When the limit is exceeded | The request is answered with HTTP 429; the response's Retry-After header says how many seconds to wait. |
| Records per request | Without a limit parameter the default number of records is returned; the number of records one request can take is capped by the system. For more, page with offset or use the bulk download endpoint. |
Querying the catalogue
To search the datasets themselves (their metadata):
GET https://ckan.buyukverianalitigi.com/api/3/action/package_search?q=istasyon&rows=10
GET https://ckan.buyukverianalitigi.com/api/3/action/package_show?id=<veri-seti-adı>
GET https://ckan.buyukverianalitigi.com/api/3/action/group_list?all_fields=truepackage_search supports every filter in the interface; by category, for instance:
GET https://ckan.buyukverianalitigi.com/api/3/action/package_search?fq=groups:ulasim
