Let's automatically collect company information (XBRL data) using the EDINET API (4/10)

In the 4th post of Advent Calendar, I will programmatically collect the data described in XBRL disclosed on EDINET.

(The program in this article is provided as it is without any guarantee, and XBRL Japan takes all responsibility for any disadvantages or problems caused by using this program, regardless of the cause. I will not bear it.)

1. What is EDINET API?

The EDINET API is an API that allows you to efficiently retrieve (XBRL) data from the EDINET database via a program, not from the EDINET screen. The EDINET API enables EDINET users to efficiently acquire disclosure information. Before using the API, please check the ** Terms of Service ** on the EDINET page.

2. Collect XBRL data with EDINET API

2.1 Program Overview

This program is a Python language program that downloads the XBRL data corresponding to the securities report disclosed on EDINET during the collection period via the EDINET API. (All codes are described in "3. Source code") ** Detailed specifications of EDINET API **, please check from the EDINET site. .. Quarterly / semi-annual reports and corrected securities reports are not supported.

2.2 Preparation

Please take the following actions before executing the program. In addition, it is necessary to install other libraries (requests, datetime, etc.) in advance.

2.2.1 Endpoint settings

Endpoints are as of December 2019. Please check each time for the latest version (ex. V1). https://disclosure.edinet-fsa.go.jp/api/v1/documents.json

2.2.3 Proxy settings

Set Proxy based on the network environment. If you don't need Proxy, remove proxies = proxies. "http_proxy" : "http://username:[email protected]:8080" "https_proxy" : "https://username:[email protected]:8080"

2.2.4 Determining the output folder

Decide where to download the XBRL data. C://Users//xxx//Desktop//xbrlReport//SR//

2.3 Execution result

The day_list is created by setting the collection start date and collection end date.

Code1

start_date = datetime.date(2019, 11, 1)
end_date = datetime.date(2019, 11,30)

Result1

day_list [datetime.date(2019, 11, 1), datetime.date(2019, 11, 2), datetime.date(2019, 11, 3), datetime.date(2019, 11, 4), datetime.date(2019, 11, 5), datetime.date(2019, 11, 6), datetime.date(2019, 11, 7), datetime.date(2019, 11, 8), datetime.date(2019, 11, 9), datetime.date(2019, 11, 10), datetime.date(2019, 11, 11), datetime.date(2019, 11, 12), datetime.date(2019, 11, 13), datetime.date(2019, 11, 14), datetime.date(2019, 11, 15), datetime.date(2019, 11, 16), datetime.date(2019, 11, 17), datetime.date(2019, 11, 18), datetime.date(2019, 11, 19), datetime.date(2019, 11, 20), datetime.date(2019, 11, 21), datetime.date(2019, 11, 22), datetime.date(2019, 11, 23), datetime.date(2019, 11, 24), datetime.date(2019, 11, 25), datetime.date(2019, 11, 26), datetime.date(2019, 11, 27), datetime.date(2019, 11, 28), datetime.date(2019, 11, 29), datetime.date(2019, 11, 30)]

Loop through day_list, set ʻurl (endpoint), params(date information), and optionallyproxies (Proxy information) for each date, requests. Get res (Response object) by executing get (url, params = params, proxies = proxies). ʻUrl specifies the endpoint corresponding to the document list API. The reason why the list of documents to be submitted is obtained by specifying " type ": 2 in params is to identify the securities report in the subsequent processing.

Code2

for index,day in enumerate(day_list):
    url = "https://disclosure.edinet-fsa.go.jp/api/v1/documents.json"
    params = {"date": day, "type": 2}

    proxies = {
        "http_proxy" : "http://username:[email protected]:8080/",
        "https_proxy" : "https://username:[email protected]:8080/"
    }

　　res = requests.get(url, params=params ,proxies=proxies)

The structure of res is defined by the 2-1-2-1 Document List API (metadata) of the EDINET API specification.pdf. The following is the contents of res corresponding to day of 2019.11.1.

Since the list of documents to be submitted is managed by results of res, loop processing is performed using results. After that, you will get ʻordinance Code(Cabinet Office Ordinance Code) andform_code (Form Code) for each document submitted in results. Since this time we are targeting securities reports, we have decided to process only the submitted documents with ʻordinance Code of 010 and form_code of 030000. Obtain the docID (document management number) of the relevant submitted documents and store it in the securities_report_doc_list (list of securities reports).

Code3

for num in range(len(json_data["results"])):
        ordinance_code= json_data["results"][num]["ordinanceCode"]
        form_code= json_data["results"][num]["formCode"]

        if ordinance_code == "010" and  form_code =="030000" :
            securities_report_doc_list.append(json_data["results"][num]["docID"])

This created a list of docIDs corresponding to the securities report.

Result3

number_of_lists： 77

The following is the code to download the XBRL data using the list. Use securities_report_doc_list to loop. ʻUrlspecifies the endpoint corresponding to the document acquisition API (note that it is not the document list API). By specifying" type ": 1 in params, it is possible to obtain the submitted document and audit report. Only when the status code of res` is 200 (when the request is successful), the XBRL data is downloaded. In addition, if you specify a date and time that is not covered by the EDINET period, such as 5 years ago, the status code of 404 (resource does not exist) may be returned.

Code4

for index,doc_id in enumerate(securities_report_doc_list):
    url = "https://disclosure.edinet-fsa.go.jp/api/v1/documents/" + doc_id
    params = {"type": 1}
    filename = "C:\\Users\\XXX\\Desktop\\xbrlReport\\SR\\" + doc_id + ".zip"
    res = requests.get(url, params=params ,stream=True)

    if res.status_code == 200:
        with open(filename, 'wb') as file:
            for chunk in res.iter_content(chunk_size=1024):
                file.write(chunk)

After execution, 77 zip files were downloaded to the specified folder. Unzip the zip file and you will see the familiar AuditDoc and PublicDoc folders. This completes the download of XBRL data.

4. How to collect reports other than securities reports

This time, we targeted securities reports, but by changing ʻordinanceCode and form_code, you can automatically collect report data written in other XBRL. For example, in the case of a quarterly report, you can change the system so that only the submitted documents with ʻordinanceCode of 010 and form_code of 043000 are processed. The following is a brief summary including corrections.

〇 Securities report if ordinanceCode == "010" and formCode =="030000" :

〇Corrected securities report if ordinanceCode == "010" and formCode =="030001" :

〇 Quarterly report if ordinanceCode == "010" and formCode =="043000" :

〇Corrected quarterly report if ordinanceCode == "010" and formCode =="043001" :

For the prefectural ordinance code and form code of all forms, see EDINET API-related materials (released on March 17, 2019). Please refer to Attachment 1_Form Code List.xlsx included in the zip file downloaded from [API Specification].
