How to Access Cosmos via Tendermint REST API

Step 1: To access Cosmos Tendermint REST, use the native access endpoint with tendermint-rest at the end:

• Network: Cosmos Mainnet
• Request Type: GET

Step 2: Authenticate your request using your API key. You can include the API key using either of the following headers:

Authorization: Bearer YOUR_API_KEY

X-API-Key: YOUR_API_KEY

Step 3: Specify a Tendermint method at the end of the query:

https://svc.blockdaemon.com/cosmos/mainnet/native/tendermint-rest/YOUR_METHOD

Example Request

https://svc.blockdaemon.com/cosmos/mainnet/native/tendermint-rest/health \
-H 'Authorization: Bearer YOUR_API_KEY' \

The following is a typical response you will get:

{
    "jsonrpc": "2.0",
