The Read API provides endpoints to retrieve blockchain data across multiple categories. These endpoints deliver standardized responses across all supported networks.

​
API Categories

​
Chain Information

  • Get Supported Chains (GET /api/chains): List all supported blockchain networks and their features
  • Get Chain Info (GET /api/chain/{chainId}): Detailed information about a specific blockchain
  • Get Validators (GET /api/{chainId}/validators): List of validators and their details
  • Get Transaction Details (GET /api/{chainId}/transaction/{transactionId}): Detailed transaction information

​
Account Operations

  • Get Account State (GET /api/{chainId}/account/{accountId}/state): Comprehensive account information including balances
  • Get Account Tokens (GET /api/{chainId}/account/{accountId}/state/tokens): List of tokens owned by an account
  • Get Account History (GET /api/{chainId}/account/{accountId}/history): Transaction history for an account

​
Utilities

  • Encode Address (POST /api/{chainId}/address/encode): Convert public key to chain-specific address format
  • Validate Address (POST /api/{chainId}/address/validate): Verify address format for a specific chain

​
Interaction Flow

Note: All Read API endpoints are stateless and return standardized responses across different blockchain networks. Pagination is supported where applicable using the nextPage parameter.

​
Chain-Specific Features

The Read API adapts to each blockchain’s capabilities: 
{
  "read": {
    "token": true, // Token information support
    "validators": true, // Validator queries support
    "transaction": {
      "native": true, // Native transaction queries
      "tokens": true, // Token transaction queries
      "staking": true // Staking transaction queries
    },
    "account": {
      "balances": {
        "native": true, // Native balance queries
        "tokens": true, // Token balance queries
        "staking": true // Staking position queries
      },
      "transactions": {
        "native": true, // Native transaction history
        "tokens": true, // Token transaction history
        "staking": true // Staking transaction history
      }
    }
  }
}

​
Response Standardization

The API provides consistent response formats across all chains:
  • Transaction states are normalized (pending, unconfirmed, confirmed, failed, unknown)
  • Transaction types are standardized (transfer, transferToken, delegate, redelegate, undelegate, claimRewards)
  • Optional include parameters allow requesting additional data (e.g., parsed and raw transaction details)
