Usage

Fetch notices for a specific year

Retrieve notices published since 2008 for a given year (e.g., '2025').

import sagikoza
accounts = sagikoza.fetch('2025')
print(accounts)
# [{'doc_id': '12345', 'link': '/pubs_basic_frame.php?...', 'id': '...', ...}, ...]

Fetch notices for the last 3 months

Call without arguments to get notices from the latest 3 months.

import sagikoza
accounts = sagikoza.fetch()
print(accounts)

Save data example

Save the retrieved data in Parquet format.

import pandas as pd
import sagikoza
accounts = sagikoza.fetch()
df = pd.DataFrame(accounts)
df.to_parquet('accounts.parquet', index=False)

Function Specification

• fetch(year: str = "near3") -> list[dict]
  • Specify a year (YYYY) or "near3" for the latest 3 months
  • Raises an exception on failure

Internal Workflow

1. Fetch notice list (POST: sel_pubs.php)
2. Fetch notice details (POST: pubs_dispatcher.php)
3. Fetch basic info (GET: pubs_basic_frame.php)
4. Fetch account details (POST: k_pubstype_00_detail.php, etc.)

Parameters required for each step are extracted from the HTML and used for subsequent page transitions.

Logging

Uses Python's standard logging module. For detailed logs:

import logging
logging.basicConfig(level=logging.INFO, format='%(asctime)s %(levelname)s %(name)s %(message)s')
import sagikoza
sagikoza.fetch()

By default, only WARNING and above are shown. For more detail, set level=logging.DEBUG.

Error Handling

• Network, HTTP, and timeout errors raise a FetchError exception
• If no records are found, a WARNING log is output

Notes

• This library retrieves data from public sources. Changes to the source website may affect functionality
• Accuracy and completeness of retrieved data are not guaranteed. Please use together with official information

Page Flow

The web pages to be scraped cannot be accessed directly by URL, but can be transitioned to the next page by making a POST request with a combination of parameters hidden within the page. Note: pubs_basic_frame.php can exceptionally be accessed via GET.

The web page contents can be obtained by accessing file using methods and payload. The contents include the payload's value, which is required for accessing other pages, in an element of parameters, which can be found using a selector.

category	file	method	payload	selector	parameters
notices	sel_pubs.php	POST	{"search_term": "near3", "search_no": "none", "search_pubs_type": "none", "sort_id": "5"}	table.sel_pubs_list > tbody > input	<input type="hidden" name="doc_id" value="15362">
submits	pubs_dispatcher.php	POST	{"head_line": "", "doc_id": "15362"}	table:nth-child(9) > tbody > tr > td.6 > a	<a href="./pubs_basic_frame.php?inst_code=0153&amp;p_id=05&amp;pn=365597&amp;re=0">（別添）</a>
