# Python

### Overview

The **Circular Enterprise APIs** provide a powerful and efficient way to **certify data on the blockchain**, ensuring immutability, transparency, and security. These APIs facilitate **account management, network configuration, data signing, and transaction monitoring**, making it easier for enterprises to integrate blockchain-based certification into their workflows.

This library is designed for developers who need to verify, sign, and submit **data certificates** using the **Circular blockchain** while maintaining seamless integration with **Python applications**.

### Installation

You can install the **Circular Enterprise APIs** via **npm**:

```bash
pip install circular-enterprise-apis
```

### Usage example

```python
from circular_enterprise_apis import CEP_Account

try:
    # Instantiate the CEP Account class
    account = CEP_Account()
    print("CEP_Account instantiated successfully.")

    address = "your-account-address"
    private_key = "your-private-key"
    blockchain = "blockchain-address"
    tx_id = ""
    tx_block = ""

    account.set_network("testnet")
    account.set_blockchain(blockchain)
    print("Test variables set.")

    if account.open(address):
        print("Account opened successfully.")

        if account.update_account():
            print(f"Nonce: {account.Nonce}")

            tx_id_temp = account.submit_certificate(
                "your-data-to-certificate",
                private_key
            )
            if tx_id_temp["Result"] == 200:
                tx_id = tx_id_temp["Response"]["TxID"]
                print(f"TxID: {tx_id}")

                resp = account.get_transaction_outcome(tx_id, 25)
                if resp["Response"]["BlockID"]:
                    block_id = resp["Response"]["BlockID"]
                    status = account.get_transaction(block_id, tx_id)

                    if status["Result"] == 200:
                        print(f"Transaction Status: {status['Response']['Status']}")
                        account.close()
                    else:
                        print("Error on retrieving transaction")
                else:
                    print("Error on retrieving transaction status")
            else:
                print("Certificate submission error")
        else:
            print(f"Update Account Error: {account.lastError}")
    else:
        print(f"Failed to open account: {account.lastError}")
except Exception as e:
    print(f"An error occurred: {e}")

```
