API Tour - Blockradar

The Blockradar API is RESTful and gives you programmatic access to every feature available on the dashboard. It is organized around the core resources you interact with: wallets, addresses, transactions, and the products built on top of them.

Before you begin, create a free Blockradar account to get your API keys. You can test against our sandbox environment before going live.

Request and response format

All request bodies and responses are formatted as JSON. Every response follows this structure:

{
  "statusCode": 200,
  "message": "Request successful",
  "data": {}
}

Property	Type	Description
`statusCode`	number	HTTP status code indicating success or failure. Use this to determine the result of every call.
`message`	string	A human-readable summary of the response. On errors, this describes what went wrong.
`data`	object or array	The result of your request. A single resource returns an object; a list returns an array.

Pagination

List endpoints return a meta object alongside data:

    "totalItems": 704,
    "itemCount": 100,
    "itemsPerPage": 100,
    "totalPages": 8,
