Berachain Fullnode (Artio Testnet)

The following query demonstrates the basic usage of LiveQuery by listing each validator in descending order of Berachain Governance token delegation:

WITH api_call as (
  SELECT
    livequery.live.udf_api(
      'https://api.testnet.berachain.flipside.services/cosmos/staking/v1beta1/validators'
    ) as rawOutput
),
formatted_results as (
  SELECT
   value:operator_address::string as operator_address,
   value:description:moniker::string as name,
   value:commission:commission_rates:rate::string as commission_rate,
   value:tokens::FLOAT / 1e+18 AS abgt
  FROM api_call, LATERAL FLATTEN (input => rawoutput:data:validators)
)
SELECT
*
FROM formatted_results ORDER by abgt DESC

This query has the three basic building blocks of a LiveQuery query:

1. Use the livequery livequery.live.udf_api function to perform an API request. You can specify the method, URL, headers, and JSON body as parameters.
2. Format the result into rows using LATERAL FLATTEN.
3. Perform the query on the formatted rows.

Start off by familiarizing yourself with the Flipside Data Studio LiveQuery feature via its documentaton. You will specifically be using the livequery.live.udf_api function, which is documented with examples here.

After you understand how to use LiveQuery, you can use it to access the Berachain fullnode RPC at https://rpc.testnet.berachain.flipside.services then query the results as though they were tabular data. You can use LiveQuery to query the API as follows:

SELECT
  livequery.live.udf_api(
    'GET', -- Method
    'https://rpc.testnet.berachain.flipside.services', -- URL
    { 'Content-Type': 'application/json' } -- Headers
    { '...' }) -- JSON Body

A body for a JSON-RPC request might look like:

{ 'jsonrpc': '2.0',
'id': 1,
'method': 'my_rpc_call',
'params': [ ... ] }

Flipside provides free, community access to public RPC nodes for emerging Blockchain networks and those that the community shows interest in. This enables builder and analysts on those networks to develop applications on those chains and gather advanced insights via LiveQuery.

Berachain is a high-performance EVM-compatible blockchain built on Proof-of-Liquidity consensus. Build applications on and analyze the Artio testnet via Flipside's public RPC endpoints.
