Circular Enterprise Python APIs for Data Certification

This library provides Python implementations of the Circular Enterprise APIs for data certification and blockchain integration. It includes classes and helper functions to interact with the Circular network, submit certificates, retrieve transactions, and manage accounts.

Features:

• Data Certification: Submit data to the blockchain for certification.
• Transaction Retrieval: Fetch transaction details by ID or block range.
• Account Management: Open, update, and close accounts.
• Secure Signing: Sign data using elliptic curve cryptography (secp256k1).
• Network Integration: Connect to different blockchain networks (mainnet, testnet, devnet). """

Installation Instructions:

Installation

You can install this library using pip:

pip install circular_enterprise_apis

Usage Instructions:

Usage

1. Opening an Account:

from circular_enterprise_apis import CEP_Account

account = CEP_Account()
account.open('a4fc8b11bfc5dc2911ab41871e6de81f500fe60f3961343b202ad78e7e297ea08')

print("Account opened successfully.")

2. Choosing a network and the blockchain:

blockchain = 'blockchain-address'
account.set_network("testnet") # chose between multiple networks such as testnet, devnet and mainnet
account.set_blockchain(blockchain)

3. Retrieve account informations

if account.update_account():
    #...

4. Submitting a Certificate:

pdata = 'Your data to certify'
private_key = 'your_private_key_here'

try:
    response = account.submit_certificate(pdata, private_key)
    print(response)
except Exception as e:
    print(f"Error: {e}")

5. Retrieving a Transaction:

#...
resp = account.get_transaction_by_id(tx_id, 0, 10)
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")
#...

Example Workflow:

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_by_id(tx_id, 0, 10)
                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}")
