Investing apps feel instantly familiar when every holding shows the company’s real logo. The Logo API resolves a logo directly from a stock or ETF ticker, no separate ticker-to-domain mapping to build or maintain.

Ticker watchlist

A ticker watchlist with logo, symbol, name, and a color-coded daily change, the core of any brokerage or portfolio screen.

Implementation

1

Get a free client ID

Register on the Developer Portal, the Logo API is free and requires no attribution.
2

Use the ticker route

Swap the usual domain segment for ticker, the CDN resolves the symbol to the company for you. The same route also accepts isin/{ISIN} and crypto/{SYMBOL}.
3

Guarantee a fallback

Keep fallback/lettermark so delisted or unrecognized symbols still render a clean monogram instead of a broken image.

Pricing

The Logo API is free, including the ticker, ISIN, and crypto routes. Create a client ID on the Developer Portal, no attribution required.

Measuring impact

Logos on holdings are a recognition and trust signal, so watch for engagement lifts on list and detail screens: taps into holdings, watchlist adds, and time spent on portfolio views. GBM uses this pattern across portfolios, watchlists, and trading screens, serving over 2.5 million logos a day.
