# Get DEXes

> Returns the seeded DEXes, including the router, factory, quoter and
settlement addresses used to price and encode a swap. Filter by chainId,
by slug, or by both; omit both to list every DEX. A slug identifies a DEX
only within one chain, so pass chainId alongside it for a single result.
