This is json-api expectation, if you have some question or ask to modify stuff please let me know feel free:

GET /info

{
	[
		{
			"chainName": "cosmoshub",
			"chanId": "cosmoshub-4",
			"logoURI": "<https://raw.githubusercontent.com/cosmos/chain-registry/master/cosmoshub/images/atom.png>",
		},
		{
			"chainName": "milkyway",
			"chanId": "milkyway",
			"logoURI": "<https://raw.githubusercontent.com/cosmos/chain-registry/master/cosmoshub/images/atom.png>",
		},

		...

	]
}

GET /info/{baseChain}

{
