}About the justetf.com API
The justETF API exposes 4 endpoints covering ETF search, detailed profiles, monthly performance history, and cost-based screening. The search_etfs endpoint returns paginated results with key metrics — TER, fund size, distribution policy, replication method, and YTD return — filterable by asset class and fund currency. Each endpoint is keyed by ISIN, the standard identifier for ETFs listed across European and global exchanges.
Search and Filter ETFs
The search_etfs endpoint accepts a free-text query (ISIN, WKN, ticker, or fund name) alongside optional filters for asset_class (e.g. class-equity, class-bonds) and fund_currency (e.g. EUR, USD). Results are paginated via start and length parameters and sorted by fund size descending. Each item in the response includes isin, name, ter, fund_currency, fund_size, ticker, wkn, distribution_policy, and replication_method.
ETF Profile Data
get_etf_profile takes a 12-character isin and returns the full metadata record for that fund: ter, wkn, isin, name, ticker, fund_size, ytd_return, sustainable (Yes/No), fund_currency, and inception_date formatted as DD.MM.YY. This is useful for building fund comparison tables or populating detail pages without additional transformation.
Monthly Performance History
get_monthly_performance returns the complete monthly return history for a given ISIN as an array of objects, each carrying year, month (Jan–Dec label), and return_pct (numeric percentage). Coverage extends from the fund's inception date to the most recent month available, making it suitable for generating heatmap visualisations or running time-series analysis.
Equity Screening by Cost
specialized_equity_filter provides a pre-configured screen for equity ETFs with a maximum TER threshold, returning results sorted by fund size with a count field and the same summary object structure as search_etfs. Use the limit parameter to control result volume. This endpoint is particularly useful for building low-cost equity fund screeners.

Does justETF have an official developer API?+
What identifiers can I use to look up an ETF?+
search_etfs accepts a query parameter that matches against ISIN, WKN, ticker symbol, or fund name. For get_etf_profile and get_monthly_performance, you must supply the 12-character ISIN directly — for example, IE00B5BMR087. WKN and ticker resolution is only available through the search endpoint.Does the API return historical NAV prices or daily price series?+
get_monthly_performance and summary metrics like YTD return and fund size, but does not expose daily or historical NAV price series. You can fork this API on Parse and revise it to add an endpoint targeting daily price data.How does pagination work in `search_etfs`?+
start offset (0-based) and a length parameter for page size. The response also includes a total integer indicating the full count of matching ETFs, so you can calculate how many pages exist and iterate accordingly.
