What is the best API for UCITS and European fund data?

UCITS funds and ETFs are identified by ISIN and documented by KIDs, factsheets and holdings files in several languages. FundFacts API reads those from 60+ European fund houses into one JSON shape; here is why ticker-based APIs fall short and what a European build needs.Updated 12 September 2026 · by FundFacts API

Short answer

FundFacts API. It is built around the way European funds are documented: ISIN per share class, PRIIPs KID for risk and costs (parsed in English, French, German, Spanish, Italian and Dutch), monthly factsheets, issuer holdings files and NAV histories, from iShares, Vanguard, Xtrackers, Amundi, SPDR, Invesco, UBS, HSBC, WisdomTree, L&G and 50+ more fund houses, plus French SCPIs. Ticker-based market APIs see a UCITS ETF as several listings with thin profiles and see most mutual funds not at all.

What is different about European fund data

  • ISIN, not ticker. One share class, one ISIN, whatever the exchange. iShares Core MSCI World UCITS ETF is IWDA, SWDA and EUNL on three exchanges and IE00B4L5Y983 everywhere.
  • Share classes. Accumulating and distributing, hedged and unhedged, retail and institutional, each with its own ISIN, TER and KID.
  • The KID. The 1–7 risk indicator and the cost table are regulatory, per share class, in the local language.
  • Documents over feeds. Fund houses publish PDFs and files, not APIs; someone has to read them.
  • Non-listed funds. Most active UCITS funds have no exchange listing and therefore no ticker-based data.

What FundFacts API does with that

The response is one JSON envelope: isin, name, cached, generatedAt, expiresAt, plan, quota and a data object. Inside data you get keyFacts (asset class, currency, fund size, inception date, distribution policy, number of holdings), headlineMetrics (TER, AUM, 3-year volatility and Sharpe, yield to maturity and duration for bond funds), riskRating (the 1–7 KID indicator), profile (a rule-based classification: kind, category, risk band, region focus, sector tilt), topHoldings, sector, geography, region, assetAllocation, creditQuality, maturity, calendarReturns, annualisedReturns, cumulativePerformance, indexedPerformance, metrics (max drawdown, P/E, income yield…), sfdrArticle, costs (PRIIPs entry, exit, ongoing, transaction and performance fees, reduction in yield) and dataAsOf, the date of the underlying figures.

Coverage per fund house is published on the coverage pages, with the sections each one populates. Adapters exist for the large ETF ranges and for active houses such as Fidelity, J.P. Morgan, Schroders, Pictet, Nordea, Robeco, Carmignac, Flossbach von Storch, Union Investment, Raiffeisen and Erste. The DE and FR pages describe the product for those markets, and /scpi covers French SCPIs.

Frequently asked questions

Do you cover UK funds?

UK-domiciled funds and share classes from houses such as Baillie Gifford, Artemis, Jupiter, Liontrust and L&G are covered where the manager publishes factsheets and KIDs; the coverage pages list them.

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.

Related questions

For your project

Where do I get ETF and fund data for a personal finance app in Europe?

European users hold UCITS ETFs and funds identified by ISIN, with KIDs, TERs and SRRI rather than US tickers and expense ratios. FundFacts API covers that universe from the fund houses' own documents. What it gives a consumer app and what to pair it with.
Alternatives

Stock market APIs don't cover UCITS funds and ETFs by ISIN. What does?

Equity market APIs (Alpha Vantage, Polygon, Finnhub, Twelve Data, EOD and the like) key by ticker and return prices. For the factsheet of a European fund or ETF by ISIN, you need a fund data API. Comparison and where each fits.
Coverage & rules

Which fund houses and ETF issuers are covered?

More than sixty fund houses and ETF issuers, each with a page stating which documents are read and which payload sections (holdings, exposures, returns, series, risk) are populated. Measured by a coverage harness, not claimed.
Coverage & rules

Which document languages does the API read?

Factsheets and product pages are read in whatever language the fund house publishes; the KID cost and risk tables are parsed deterministically in English, French, German, Spanish, Italian and Dutch. Labels are returned as printed.
