Valuation data — the fuller per-stock valuation record: the core ratios plus market capitalization and shares outstanding, per trading day.

DerivedSource: TWSE / TPEx / MOPS·Plan: free·Cost: 2 credits·GET /v2/datasets/valuation-data

Valuation data is a Taiwan market dataset sourced from TWSE / TPEx / MOPS, served by TW Market Data as GET /v2/datasets/valuation-data.

Overview

valuation-data is a derived dataset that extends the core valuation ratios with market capitalization and shares-outstanding context per stock per trading day, computed from the official price and MOPS financial inputs. The lineage block points back to those official sources so each figure is reproducible rather than a standalone assertion.

Getting started

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

curl "https://api.twmarketdata.com/v2/datasets/valuation-data?symbol=1101" \
  -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

import requests

resp = requests.get(
    "https://api.twmarketdata.com/v2/datasets/valuation-data",
    params={"symbol": "1101"},
    headers={"X-API-Key": "sk_live_..."},

print(resp.json()["rows"])

OpenAPI

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

Notes & limitations

Derived, not disclosed: market cap and ratios combine the official price with point-in-time shares and financial figures, which get restated — pin as_of for backtests so a past valuation uses only figures public at that moment.
