Hydrachain Explorer Requester

PyPI PyPI License

Easy to use library for accessing the Hydrachain Explorer endpoints. Postman collection of all request can be found here.

Installation

PyPI:

pip install hydrachain-explorer-requester

Local:

Download the latest release and run the below command to install it globally:

pip install .

Examples

Block:

from hydrachain_explorer_requester.explorer_requester import ExplorerRequester

explorer_requester = ExplorerRequester()

# Block - https://explorer.hydrachain.org/block/123/
block_response = explorer_requester.get_block(123)

print(block_response)

Address Transactions:

from hydrachain_explorer_requester.explorer_requester import ExplorerRequester

explorer_requester = ExplorerRequester()

# Address - https://explorer.hydrachain.org/address/HCiMdPYCsdPPvbjxHQMmK8QVBEGwextvir/
address_transactions = explorer_requester.get_address_transactions("HCiMdPYCsdPPvbjxHQMmK8QVBEGwextvir")

print(address_transactions)

Address Transactions - Query Parameters:

from hydrachain_explorer_requester.explorer_requester import ExplorerRequester

explorer_requester = ExplorerRequester()

# Address - https://explorer.hydrachain.org/address/HCiMdPYCsdPPvbjxHQMmK8QVBEGwextvir/

query_parameters = TransactionsQueryParameters()
query_parameters.set_page(0)
query_parameters.set_page_size(3)
query_parameters.set_from(555555)
query_parameters.set_to_block(666666)

address_transactions = explorer_requester.get_address_transactions("HCiMdPYCsdPPvbjxHQMmK8QVBEGwextvir", query_parameters)

print(address_transactions)

Search:

from hydrachain_explorer_requester.explorer_requester import ExplorerRequester

def search(value: str) -> dict:
    search_response = explorer_requester.search(value)

    if 'type' not in search_response:
        return {}

    type = search_response['type']
    match type:
        case 'block':
            return explorer_requester.get_block(int(value))
        case 'transaction':
            return explorer_requester.get_transaction(value)
        case 'address':
            return explorer_requester.get_address(value)
        case 'contract':
            address = search_response['address']
            return explorer_requester.get_contract(address)
        case _:
            print(f'Type {type} not implemented!')
            return {}


explorer_requester = ExplorerRequester()

# Block - https://explorer.hydrachain.org/block/1234
print(search('1234'))

# Transaction - https://explorer.hydrachain.org/tx/23ebd8cb30e701b1dce693bb427092dcbf7091dd5cb263d9962b9245a38662f6
print(search('23ebd8cb30e701b1dce693bb427092dcbf7091dd5cb263d9962b9245a38662f6'))

# Address - https://explorer.hydrachain.org/address/H7FYCLijimtbYk7gdN1hmweftuWLQni3m5
print(search('H7FYCLijimtbYk7gdN1hmweftuWLQni3m5'))

# Contract/Token - https://explorer.hydrachain.org/contract/4ab26aaa1803daa638910d71075c06386e391147
print(search('LockTrip'))
  • Why we didn't implement the search?
    • Because the idea of the library is provide you with the raw responses, without any modification.

Configuration: (Optional)

import logging

import requests
from requests.adapters import HTTPAdapter

import hydrachain_explorer_requester
from hydrachain_explorer_requester.explorer_requester import ExplorerRequester

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

#Configure the used requester
http_adapter = HTTPAdapter(
    pool_connections=requests.adapters.DEFAULT_POOLSIZE,
    pool_maxsize=requests.adapters.DEFAULT_POOLSIZE,
    max_retries=3,
    pool_block=requests.adapters.DEFAULT_POOLBLOCK,
)

#Place the configured requester configuration
explorer_requester = ExplorerRequester(
    timeout_seconds = 0.5, # 500 milliseconds
    http_adapter=http_adapter
)

# Configure the level of logging.
hydrachain_explorer_requester.explorer_requester._logger.setLevel(logging.INFO)

block = explorer_requester.get_block(1234)
logger.info(block)

Functionalities:

  • All of the explorer requests are supported
  • You can configure the used requester in the library using the timeout_seconds and http_adapter. Specify hooks if you want via hooks and also configure the logger.
  • You can overwrite specific explorer URL. Examples present under /examples
  • You can overwrite a query parameter. Examples present under /examples

Versions

This library supports Python 3.11+.

hydrachain-explorer-requester uses a modified version of Semantic Versioning for all changes to the helper library. It is strongly encouraged that you pin at least the major version and potentially the minor version to avoid pulling in breaking changes.

Semantic Versions take the form of MAJOR.MINOR.PATCH

When bugs are fixed in the library in a backwards-compatible way, the PATCH level will be incremented by one. When new features are added to the library in a backwards-compatible way, the PATCH level will be incremented by one. PATCH changes should not break your code and are generally safe for upgrade.

When a new large feature set comes online or a small breaking change is introduced, the MINOR version will be incremented by one and the PATCH version reset to zero. MINOR changes may require some amount of manual code change for upgrade. These backwards-incompatible changes will generally be limited to a small number of function signature changes.

The MAJOR version is used to indicate the family of technology represented by the helper library. Breaking changes that require extensive reworking of code will cause the MAJOR version to be incremented by one, and the MINOR and PATCH versions will be reset to zero. We understand that this can be very disruptive, so we will only introduce this type of breaking change when absolutely necessary. New MAJOR versions will be communicated in advance with Release Candidates and a schedule.

Only the current MAJOR version of hydrachain-explorer-requester is supported. New features, functionality, bug fixes, and security updates will only be added to the current MAJOR version.
