How to Connect to Cardano

🚧

Note

Cardano does not provide regular RPC endpoints by default. To address this, Ogmios offers an RPC-like interface connected to Cardano's mini-protocols.

Ogmios can be enabled for full nodes.

curl --location --request POST 'YOUR_ENDPOINT_URL' \
  --header 'X-Auth-Token: YOUR_AUTH_TOKEN' \
  --header 'Content-Type: application/json' \
  --data-raw '{
    "jsonrpc": "2.0",
    "id": 1,
