A real response from this endpoint. Rows are returned under "data", and provenance is carried in the shape shown below — it is not identical across datasets, so read this page's rather than assuming another's.

Captured from the live API on 2026-07-20.

Chinese data values are shown as a marker here so this page stays in English; the /zh page shows them verbatim.

Provenance

These columns are returned alongside the data and record where the row came from. They are provenance, not the dataset's subject matter, so they are listed here rather than in the field table.

Getting started

Put your key in the X-API-Key header.
Add query parameters (symbol, date range, limit).
Send the request and read the data array.

curl "https://api.twmarketdata.com/v2/datasets/industry-index-daily?symbol=2330" \  -H "X-API-Key: sk_live_..."

Filtering

Parameter	Required	Type	Description
`symbol`	Yes	string	Ticker, e.g. 2330.
`start_date`	No	string (YYYY-MM-DD)	Start of the query range.
`end_date`	No	string (YYYY-MM-DD)	End of the query range.
`limit`	No	integer	Maximum rows to return.

Python

A first call:

import requests resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/industry-index-daily",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()print(resp.json()["data"])

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/industry-index-daily",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()for row in resp.json()["data"]:    print(row)

OpenAPI

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

Notes & limitations

The backend registry status is `partial` and it exposes no grain or field list, so no field table is shown and no claim of complete coverage is made.

This dataset returns its rows under "data". The envelope differs between datasets, so read this one rather than reusing another page's shape.

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