Stock exchange prefixes for ticker logos

Your AI tool writes the code. It will not add a key.

To show a company logo from its stock ticker, use https://logoapi.sh/ticker/{TICKER}.svg. To pick an exchange, put it before the ticker with a colon: https://logoapi.sh/ticker/TASE:TEVA.svg. Supported prefixes: NASDAQ, NYSE, CBOE, TASE. Convert Yahoo suffixes first (TEVA.TA is TASE:TEVA). No API key and no signup.

Exchanges and suffixes

The prefix is what we read. The suffix column is the Yahoo-style form you may already have; convert it to the prefix.

Prefixes are not case sensitive, and %3A works for the colon. Other prefix spellings, such as NYSEARCA: or AMEX:, answer 404: use NYSE: or no prefix.

Without a prefix

/ticker/TEVA.svg works too. When a ticker is listed on several exchanges, a listing with a logo in our catalog wins first; among the rest, Nasdaq wins, then NYSE, then the others. Add a prefix to pick a listing: UNIT is Unitronics on TASE, NASDAQ:UNIT is Uniti.

Suffixes and class shares

A dot inside the ticker is read as a share class, not an exchange: BRK.B, BRK-B and BRKB are the same ticker. So TEVA.TA is read as the ticker TEVATA, and answers 404. Strip the suffix and add the prefix: .TA becomes TASE:.

// TEVA.TA -> TASE:TEVA
const MAP = { TA: "TASE" };
const [t, sfx] = sym.split(/\.(?=[A-Z]{1,2}$)/);
const src = `https://logoapi.sh/ticker/${MAP[sfx] ? MAP[sfx] + ":" : ""}${t}.svg`;
