How to Access Bitcoin API

Step 1: To access Bitcoin, use the following native access endpoints:

  • Network: Bitcoin Mainnet
  • Request Type: POST
https://svc.blockdaemon.com/bitcoin/mainnet/native
  • Network: Bitcoin Testnet
  • Request Type: POST
https://svc.blockdaemon.com/bitcoin/testnet/native

Step 2: You should authorize your request. Learn more: Authentication Guide

Step 3: Specify a Bitcoin method in the request body:

{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "YOUR_METHOD",
    "params": []
}

Example Request

Using Bitcoin Custom Method

📘

See the list of custom methods here.

Here’s a cURL example that shows how to use the bd_listtransactions method to retrieve native transactions for a particular Bitcoin address or transaction IDs.

curl -X POST \
https://svc.blockdaemon.com/bitcoin/mainnet/native \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
    "jsonrpc": "1.0",
    "id": "curltest",
    "method": "bd_listtransactions",
    "params": [
        "bc1q84e0f2qswgzth4tavedrv35f6fv9669ljww2ww",
        {
            "block_start": 850000,
            "block_end": 862810,
            "type": "all",
            "verbose": false,
            "page_size": 20,
            "page_token": "OTIyMzM3MjAzNjg1MzkxMzY5NCM1YmIyZWY3MjExYTgyNjE0ODkxZDAyNzQzYzUzYjZkNzU5ZTE2MmU2MTFiNGQxZjljMDYyOTM3YzdjMzdkNjA3",
            "order": "asc"
        }
    ]
}'

From the request above, you will get the response below:

{
    "id": "curltest",
    "result": {
        "transactions": [
            "74980dd4049324587471e266ff144f0d75d81f0f44767deaf6babdc9b8703c57",
            "08ba4c433016377851f2e5b4fdad14aa715cab8b2d6393828e1539775e5aabb2",
            "f594f9fbd52014308544030cdf154236b65f24b5ab832e5447fff1509decca9d"
        ],
        "page_token": "OTIyMzM3MjAzNjg1MzkxNzA2NSNmNTk0ZjlmYmQ1MjAxNDMwODU0NDAzMGNkZjE1NDIzNmI2NWYyNGI1YWI4MzJlNTQ0N2ZmZjE1MDlkZWNjYTlk"
    }
}

Using Bitcoin RPC Method

Here is a cURL example for using getblockcount to get the height of the most-work fully-validated chain in Bitcoin Mainnet:

curl -X POST \
https://svc.blockdaemon.com/bitcoin/mainnet/native \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
    "jsonrpc": "1.0",
    "id": "curltest",
    "method": "getblockcount",
    "params": []
}'

The following is a typical response you will get:

{
    "result": 748958,
    "error": null,
    "id": 1
}
