How To Access Bitcoin API

Step 1: To access the available Bitcoin methods, 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

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": "2.0", "id": 1, "method": "getblockcount", "params": []}'

The following is a typical response you will get:

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