# Bitcoin tooling

> Connect to your Chainstack Bitcoin node using JSON-RPC API with curl or Postman, and set up Bitcoin Core for direct blockchain interaction.

Get started with a [reliable Bitcoin RPC endpoint](https://chainstack.com/build-better-with-bitcoin/) to use the tools below.

## JSON-RPC API

Interact with your Bitcoin nodes using [JSON-RPC API](https://en.bitcoin.it/wiki/API_reference_\(JSON-RPC\)#JSON-RPC).

Use [curl](https://curl.haxx.se) or [Postman](https://www.getpostman.com) to invoke [Bitcoin API methods](https://bitcoin.org/en/developer-reference#bitcoin-core-apis).

Example below demonstrates how to get basic network information from your Bitcoin node HTTPS endpoint:

<CodeGroup>
  ```bash cURL theme={"system"}
  curl YOUR_CHAINSTACK_ENDPOINT -d '{"method":"getblockchaininfo","params":[],"id":1}'
  ```
</CodeGroup>

where YOUR\_CHAINSTACK\_ENDPOINT is your node HTTPS endpoint protected either with the key or password

## Python

Work with Bitcoin from your Python application.

1. Install [bitcoincli](https://github.com/chainstack/bitcoincli).
2. Configure the client to use `host` and `port` of the node HTTPS endpoint, the corresponding node `username`, and `password`:

   <CodeGroup>
     ```python Python theme={"system"}
     from bitcoincli import Bitcoin

     host = "nd-123-456-789.p2pify.com"
     port = "443"
     username = "user-name"
     password = "pass-word-pass-word-pass-word"

     bitcoin = Bitcoin(username, password, host, port)
     ```
   </CodeGroup>
3. Invoke any methods from the [Bitcoin API specification](https://bitcoin.org/en/developer-reference#bitcoin-core-apis):

   <CodeGroup>
     ```python Python theme={"system"}
     info = bitcoin.getblockchaininfo()
     print(info)
     ```
   </CodeGroup>

The example code above should output basic network information:

<CodeGroup>
  ```python Python theme={"system"}
  {u'pruned': False, u'blocks': 603580, u'chainwork': u'00000000000000000000000000000000000000000a0baf330c67a89653c67005', u'chain': u'main', u'difficulty': 12720005267390.51, u'bip9_softforks': {u'csv': {u'status': u'active', u'since': 419328, u'timeout': 1493596800, u'startTime': 1462060800}, u'segwit': {u'status': u'active', u'since': 481824, u'timeout': 1510704000, u'startTime': 1479168000}}, u'warnings': u'', u'softforks': [{u'version': 2, u'id': u'bip34', u'reject': {u'status': True}}, {u'version': 3, u'id': u'bip66', u'reject': {u'status': True}}, {u'version': 4, u'id': u'bip65', u'reject': {u'status': True}}], u'initialblockdownload': False, u'headers': 603580, u'mediantime': 1573647950, u'verificationprogress': 0.9999919488385801, u'bestblockhash': u'000000000000000000068b536474a44f9e0a0a0ab6be75d9afdaddc8c513bcea', u'size_on_disk': 282597514457}
