Fee Configuration

All transactions require a fee configuration that specifies how transaction fees will be paid. You can pay fees in either SOL or USDC - for full details on fee calculation, supported currencies, and response formats, see our supported fee currencies documentation. Example fee configuration: 
{
  "fee_config": {
    "currency": "usdc",
    "payer_address": "BmB8q3Q5N1CruWDjsnYXNnXhfL4bgQovEMYhzVLar1uR"
  }
}

​
Response Format

API responses vary by endpoint type but always follow these principles:
  • All responses are returned in JSON format
  • Error responses follow a consistent format
  • Successful responses vary based on the endpoint type

​
Success Response Types

  1. Transaction Endpoints Most endpoints return a prepared transaction and fee information:
{
  "transaction": "AQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABAAEDpXW3HkEQR9QEa5C8/Qk4nJcaYkdlhqmxV4k",
  "fee": {
    "amount": "1000000",
    "amount_decimal": "1.0",
    "currency": "usdc",
    "sol_equivalent": {
      "amount": "5000",
      "amount_decimal": "0.000005"
    }
  }
}
  1. Smart Account Creation The create smart account endpoint returns just the address:
{
  "smart_account_address": "AbCd...XyZ"  // Ready to use immediately
}
  1. Query Endpoints Query endpoints return specific data structures relevant to their function. For example, getting spending limit details:
{
  "smart_account_address": "AbCd...XyZ",
  "spending_limit": {
    // Spending limit specific details
  }
}

​
Error Response

All endpoints use a consistent error format: 
{
  "error": "Invalid request parameters"
}

​

  • transaction: Base64 encoded Solana transaction (when applicable)
  • smart_account_address: The wallet address of a smart account
  • fee: Fee information when a transaction is involved
    • amount: Raw amount in base units (e.g., USDC with 6 decimals)
