How to Access Cosmos REST API

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

• Network: Cosmos Mainnet
• Request Type: GET

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

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 Cosmos method at the end of the query:

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

Example Request

Here is a cURL example for using params to query all parameters in Cosmos Mainnet:

curl -X GET\
https://svc.blockdaemon.com/cosmos/mainnet/native/cosmos-rest/cosmos/auth/v1beta1/params
-H 'Authorization: Bearer YOUR_API_KEY' \

The following is a typical response you will get:

{
    "params": {
        "max_memo_characters": "512",
        "tx_sig_limit": "7",
        "tx_size_cost_per_byte": "10",
        "sig_verify_cost_ed25519": "590",
        "sig_verify_cost_secp256k1": "1000"
    }
}
