Chains

List all Tendermint-based chains we support and the availability of various services (RPC, API, state-sync, snapshot and live peers).

Example request:
curl --request GET \
    --get "https://polkachu.com/api/v1/chains" \
    --header "Content-Type: application/json" \
    --header "Accept: application/json"
const url = new URL(
    "https://polkachu.com/api/v1/chains"
);

const headers = {
    "Content-Type": "application/json",
    "Accept": "application/json",
};

fetch(url, {
    method: "GET",
    headers,
}).then(response => response.json());

Example response (200):

Show headers 
cache-control: no-cache, private
content-type: application/json
x-ratelimit-limit: 60
x-ratelimit-remaining: 58
access-control-allow-origin: *
