Contract Calls

The Contract Calls Durable Object provides a caching layer for interacting with Stacks smart contracts. It allows you to make read-only function calls to any Stacks smart contract while benefiting from caching, rate limiting, and automatic retries.

Features

• Caching: Responses are cached to reduce API calls and improve performance

• Rate Limiting: Prevents exceeding Stacks API rate limits

• Automatic Retries: Failed requests are automatically retried with exponential backoff

• Validation: Contract addresses, functions, and arguments are validated before execution

• Standardized Responses: All responses follow a consistent format with success/error handling

• Error Tracking: Unique error IDs for easier debugging and tracking

Base Path

All contract call endpoints are available under:

/contract-calls

Response Format

All endpoints return responses in a standardized format:

Success Response

{
  "success": true,
  "data": {
    // The actual response data
  }
}

Error Response

{
  "success": false,
  "error": {
    "id": "unique-error-id",
    "code": "ERROR_CODE",
    "message": "Human-readable error message",
    "details": {
      // Optional additional error details
    }
  }
}
