Callsign Lookup Tools¶

A QRZ, Callook, HamQTH, and QRZCQ API interface in Python with sync and async support.

CLI Usage¶

Note

To use the CLI, install with the extra cli (e.g. pip install callsignlookuptools[cli]) or otherwise install the library typer[all] and click-help-colors.

callsignlookuptools has a basic CLI interface, which can be run using:

$ python3 -m callsignlookuptools

It can be used with the following arguments:

$ python3 -m callsignlookuptools --help
Usage: python -m callsignlookuptools [OPTIONS] COMMAND [ARGS]...

  A QRZ, Callook, HamQTH, and QRZCQ API interface in Python with sync and async support.

Options:
  -v, --version  Show the version of this program and exit.
  -h, --help     Show this message and exit.

Commands:
  callook  Use Callook to look up a callsign
  hamqth   Use HamQTH to look up a callsign
  qrz      Use QRZ to look up a callsign
  qrzcq    Use QRZCQ to look up a callsign

Each lookup source is a subcommand, and any source-specific options can be viewed by using the -h or --help argument on that subcommand.

For example, the QRZ lookup source has the following options:

$ python3 -m callsignlookuptools qrz --help
Usage: python -m callsignlookuptools qrz [OPTIONS] CALL

  Use QRZ to look up a callsign

  Requires a QRZ account and an XML Logbook Data or QRZ Premium subscription

Options:
  -u, --user, --username TEXT  QRZ username (will be prompted if not provided)  [required]
  -p, --pass, --password TEXT  QRZ password (will be prompted if not provided)  [required]
  CALL                         The callsign to look up  [required]
  -h, --help                   Show this message and exit.

An example invocation that looks up W1XYZ on QRZ, where the username is provided, and the password will be prompted for:

$ python3 -m callsignlookuptools qrz --username w1aw W1XYZ

Installation¶

callsignlookuptools requires Python 3.9 at minimum. Install by running:

# synchronous requests only
$ pip install callsignlookuptools

# asynchronous aiohttp only
$ pip install callsignlookuptools[async]

# both sync and async
$ pip install callsignlookuptools[all]

# enable the CLI
$ pip install callsignlookuptools[cli]

Note

If requests, aiohttp, or typer[all] and click-help-colors are installed another way, you will also have access to the sync, async, or command-line interface, respectively.

API Support¶

Some of the supported callsign lookup APIs require accounts and/or paid subscriptions to be used.

Site	Requirements
QRZ	QRZ account and XML Logbook Data or QRZ Premium subscription
Callook	None
HamQTH	HamQTH account
QRZCQ	QRZCQ account and QRZCQ Premium subscription

Getting Started¶

Using CallsignLookupTools is designed to be very simple. The following examples show basic use of the library.

Sync¶

# import the sync client for the service you want to use
from callsignlookuptools import QrzSyncClient, CallsignLookupError

# instantiate the lookup client
# some clients require a username, password, or other arguments
lookup_client = QrzSyncClient(username="...", password="...")

# perform a search query
try:
    # this will be a CallsignData object
    lookup_result = lookup_client.search("W1AW")
# if an error occurs while performing the query,
# it will raise a CallsignLookupError
except CallsignLookupError as e:
    print(e)
else:
    print(lookup_result)

Async¶

import asyncio

# import the async client for the service you want to use
from callsignlookuptools import QrzAsyncClient, CallsignLookupError

# instantiate the lookup client
# some clients require a username, password, or other arguments
lookup_client = QrzAsyncClient(username="...", password="...")

# for the async client, queries must be run inside coroutines
async def run_query():
    # perform a search query
    try:
        # this will be a CallsignData object
        lookup_result = await lookup_client.search("W1AW")
    # if an error occurs while performing the query,
    # it will raise a CallsignLookupError
    except CallsignLookupError as e:
        print(e)
    else:
        print(lookup_result)
    # if you're using the internally-generated session,
    # make sure to clean up
    await lookup_client.close_session()

# run the task
loop = asyncio.get_event_loop()
loop.run_until_complete(run_query())
