Yahoo Finance doesn't give me ETF holdings or fund data by ISIN. What can I use instead?

Yahoo Finance and yfinance cover prices, not factsheets, and key by ticker per exchange rather than ISIN. For holdings, sector weights, TER, risk indicator and KID costs of UCITS funds, use an ISIN-keyed fund data API. Comparison and code.Updated 12 September 2026 · by FundFacts API

Short answer

Yahoo Finance is a price source: yfinance gives you quotes and some summary fields per exchange ticker, but not the factsheet (full top holdings with weights, sector and country tables, TER and KID costs, the 1–7 risk indicator, calendar returns versus benchmark) and it does not key by ISIN, so a UCITS ETF listed on five exchanges is five tickers. FundFacts API returns exactly those figures from the fund house's documents for any ISIN, with a free plan of 15 lookups a month. Keep Yahoo for prices and use the API for the factsheet.

Where each one fits

Need	Yahoo Finance / yfinance	FundFacts API
Daily or intraday market price of an ETF	✓	✗ (monthly NAV series only)
Look up by ISIN (one identifier per share class)	✗ (ticker per exchange)	✓
Top holdings with weights, holdings count	Partial, mostly US ETFs	✓ from the issuer's holdings file or factsheet
Sector, country, asset, credit-quality tables	Partial	✓
TER / ongoing charges, KID cost table	Sometimes an expense ratio	✓ TER plus entry, exit, ongoing, transaction, RIY
1–7 SRRI / SRI risk indicator, SFDR article	✗	✓
Calendar and annualised returns vs benchmark	Partial	✓ as printed on the factsheet
UCITS and other European funds	Thin	Core coverage
Terms for use in a product	Unofficial scraping	Commercial licence on Pro and above

The ISIN problem in one example

iShares Core MSCI World UCITS ETF is IWDA on Euronext Amsterdam, SWDA on the London Stock Exchange, EUNL on Xetra and IWDA on Borsa Italiana. In Yahoo Finance those are four tickers with four partially populated profiles. In an ISIN-keyed API it is one identifier, IE00B4L5Y983, with one payload:

python
import os, requests
r = requests.get(f"https://fundfactsapi.com/api/v1/funds/IE00B4L5Y983", headers={"Authorization": f"Bearer {os.environ['FUNDFACTS_API_KEY']}"}, timeout=300)
d = r.json()["data"]
print(d["headlineMetrics"]["ter"], d["riskRating"], d["topHoldings"][:5], d["sector"][:3], d["dataAsOf"])

Using both

A typical stack keeps yfinance (or the broker's feed) for prices and charts and calls the fund API once a day per ISIN for the factsheet fields, cached until expiresAt. NAV vs market price explains why the two numbers differ and which to show where.

The Free plan gives 15 lookups a month without a card, enough to check the funds you care about. Starter is $9.99 a month for 500 requests with batch calls of 10 ISINs, HTML and PDF factsheets and the AI companion kit. Pro is $49 for 9,000 requests, batches of 50, portfolio look-through, holdings overlap, document extraction and a commercial licence. Scale is $249 for 60,000 requests, batches of 200, a change feed, webhooks and bulk export.

Verify it yourself

The demo endpoint returns the live payload for a fund that is already in the store, without a key. Everything on this page can be checked against it.

Frequently asked questions

Does the API return the ticker for an ISIN?

Not as a field. The ISIN is the key; the search endpoint resolves names to ISINs. Ticker-to-ISIN mapping is exchange-specific and is best taken from your broker or the exchange.

Which ISINs work?

Any share class of a UCITS fund, ETF, money-market fund or open-end fund whose management company publishes a product page, factsheet and KID. Each share class has its own ISIN and is looked up on its own. Stocks, bonds and indices are not funds and return 404 fund_not_found.

How current are the figures?

Each ISIN is re-read from the fund house's documents at most every 24 hours. data.dataAsOf is the as-of date printed on the documents, typically the last month end for a factsheet and the last trading day for holdings files.
