Step 1: To access the available Substrate Sidecar methods, use the native access endpoint with /parachain at the end:

Network: Karura Mainnet
Request Type: GET / POST

https://svc.blockdaemon.com/karura/mainnet/native/parachain

Step 3: Add a Substrate Sidecar method at the end of the query:

https://svc.blockdaemon.com/karura/mainnet/native/parachain/YOUR_METHOD

Step 4: For POST requests, specify the data required by the method in the request body.

Example Request for Substrate Sidecar API

Here is a cURL example for using GET /blocks/head/header to get the header of the most recently finalized block in Karura Mainnet:

curl -X GET \
https://svc.blockdaemon.com/karura/mainnet/native/parachain/blocks/head/header \
-H 'Authorization: Bearer YOUR_API_KEY'

The following is a typical response you will get:
