Funds Logo API – Mutual & Index Fund Logos by ISIN

A funds logo API is a REST API that resolves logos for investment funds -- ETFs, index funds, mutual funds, and money market funds -- by identifier, instead of requiring every application to source and host fund-provider brand assets individually. Ours covers major asset managers (BlackRock, Vanguard, State Street, Invesco, ARK, VanEck, Xtrackers, Amundi, Fidelity, First Trust, Franklin Templeton, HSBC, J.P. Morgan, Legal & General, UBS, WisdomTree, Robeco, and more) and returns SVG and PNG logos by ISIN or ticker.

Both. An ETF is itself a type of fund, so the same endpoint and identifier catalogue covers exchange-traded funds, traditional open-end mutual funds, and money market funds. If your product only needs ETF-specific framing, see the dedicated ETF Logo API instead.

Send a GET request to api.logostream.dev/stocks/isin/{ISIN}?key=YOUR_KEY. Funds are identified by ISIN rather than ticker in most cases, particularly for UCITS funds and mutual funds that don't trade on an exchange under a single symbol.

Yes -- this is one of the most common uses. Robo-advisors typically build portfolios from a small, repeated set of core funds. Resolve each fund's logo once by ISIN and reuse it across every client account, statement, and rebalancing screen.

By default the API returns a monogram fallback generated from the fund's ticker. Add ?fallback=404 to receive a 404 instead, if your application should handle missing fund logos differently (e.g. hiding the row rather than showing a placeholder).

Yes, on the Community plan with attribution -- see /pricing for current rate limits and paid tiers that remove the attribution requirement and add caching.
