The routes endpoint lists every supported bridge route; the quote endpoint prices a bridge transfer — relayer capital fee, gas fee, LP fee, total fee, amount received and estimated fill time; the limits endpoint returns the min and max bridgeable amount for a route; the chains endpoint lists supported chains. Live, no key, nothing stored. Distinct from DEX, lending, staking and price feeds — this is Across's own cross-chain bridge fee, route and fill-time layer.",
