Tax & business registration

Business-registration reference from the MOEA — the public registration record for a company (registered name, status, paid-in capital), via data.gov.tw.

ReferenceSource: MOEA·Plan: pro·Cost: 1 credits·GET /v2/datasets/tax-business-registration

Overview

tax-business-registration is a reference dataset: one active record per registered business resolving an identifier to its public registration basics, sourced from the MOEA via data.gov.tw. It is public business-registration reference only — the registered name, status and capital that the MOEA publishes openly — not private tax-filing or confidential tax data. Each row carries a source role and lineage so a field can be reconciled against the open dataset.

FieldTypeDescription
business_idstringMOEA unified business number (8-digit registration id).
company_namestringRegistered company name.
registration_statusstringRegistration status (e.g. active / dissolved).
paid_in_capitalnumberRegistered paid-in capital (TWD).
registered_citystringRegistered location (city / county).
source_rolestringCanonical source role (moea_business_registration).

Example response

TODO — no real response has been captured for this dataset yet. It needs an entitled API key, or its required parameters are not yet known. Rather than show an example nobody has observed, this section stays empty.

Getting started

  1. Put your key in the X-API-Key header.
  2. Add query parameters (symbol, date range, limit).
  3. Send the request and read the returned payload.
curl "https://api.twmarketdata.com/v2/datasets/tax-business-registration?symbol=2330" \  -H "X-API-Key: sk_live_..."

Filtering

ParameterRequiredTypeDescription
symbolNostringTicker to filter to a single security.
limitNointegerMaximum rows to return.

Python

A first call:

import requests resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/tax-business-registration",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()print(resp.json())

With a date-range filter:

import requests # The full verified example — the same call with every supported filter set.resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/tax-business-registration",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()print(resp.json())

OpenAPI

This endpoint is GET /v2/datasets/tax-business-registration. The full machine-readable schema (parameters, security, response envelope) lives in the OpenAPI spec.

Notes & limitations

  • Public business-registration reference only: it exposes what the MOEA publishes openly (registered name, status, capital), not private tax filings or any confidential tax data.
  • The example business_id is masked (########); a real query returns the actual 8-digit MOEA unified business number from the open dataset.

Request & Response

Request

curl "https://api.twmarketdata.com/v2/datasets/tax-business-registration?symbol=2330&limit=5" \  -H "X-API-Key: $TWMD_API_KEY"

Authenticate with the X-API-Key header, using a sk_live_ key issued in the dashboard.

Response

TODO — no response has been captured for this dataset yet (it needs an entitled key, or its required parameters are not yet known). No example is shown rather than an invented one.

The grade badge on this page is a documentation classification, not a response field.
