uptime-kuma-api2

A wrapper for the Uptime Kuma Socket.IO API — with full v2 support

About this project: uptime-kuma-api2 is an independent continuation of lucasheld/uptime-kuma-api, the original library created by Lucas Held. That project appears to be unmaintained — its last release was in 2023, and open issues and pull requests (including several adding Uptime Kuma 2.x support) have sat unreviewed and unmerged. Rather than leave 2.x users without a working library, this project carries the code forward with full v2.x support while keeping backward compatibility with v1.x.

It began as a fork and is published under the original MIT license. Lucas Held's copyright is retained in LICENSE alongside the later changes — full credit to him for building the foundation. This is a continuation, not a replacement: if the original project becomes active again, the changes here are available to contribute back upstream.

Naming: the PyPI distribution is uptime-kuma-api2, while the import package remains uptime_kuma_api so existing code works unchanged. The similarly named PyPI projects uptime-kuma-api (the original) and uptime-kuma-api-v2 (a different maintainer) are separate from this one. The repository was renamed from uptime-kuma-api-v2 to uptime-kuma-api2 to match the PyPI name; the old URL redirects automatically.

uptime-kuma-api2 is a Python wrapper for the Uptime Kuma Socket.IO API.

This package was originally developed to configure Uptime Kuma with Ansible. The original Ansible collection can be found at https://github.com/lucasheld/ansible-uptime-kuma.

Python version 3.8+ is required. Tested on 3.8 through 3.13.

Supported Uptime Kuma versions:

One install covers both majors — there is no separate v1 line to pin to. Server-version-specific behaviour is gated at runtime, so the same package works against a 1.x and a 2.x server.

The range above is what the project tests against. The Docker matrix in run_tests.sh exercises the version gate boundaries across it — 1.21.3, 1.22.x, 1.23.x, 2.0.0, 2.1.0 and 2.5.0 — and this tree was additionally live-verified end to end against 1.23.2, 2.0.2 and 2.5.0.

Uptime Kuma older than 1.21.3 is not supported: that support was dropped in uptime-kuma-api 1.0.0. If you run one of those servers, use 0.13.0.

Earlier release lines, kept as a record of what each published version was documented to support:

Releases 1.2.1 and earlier were published under the upstream uptime-kuma-api name; 2.0.0 onward are published as uptime-kuma-api2.

Installation

uptime-kuma-api2 is available on the Python Package Index (PyPI).

You can install it using pip:

pip install uptime-kuma-api2

Documentation

The API reference is published on Read the Docs.

You can also build it locally with Sphinx:

pip install -r dev-requirements.txt
cd docs && make html

Note: uptime-kuma-api.readthedocs.io (without the 2) is the original project's site and does not cover this project's v2 features.

Example

Once you have installed the python package, you can use it to communicate with an Uptime Kuma instance.

To do so, import UptimeKumaApi from the library and specify the Uptime Kuma server url (e.g. 'http://127.0.0.1:3001'), username and password to initialize the connection.

>>> from uptime_kuma_api import UptimeKumaApi, MonitorType
>>> api = UptimeKumaApi('INSERT_URL')
>>> api.login('INSERT_USERNAME', 'INSERT_PASSWORD')

Note on the Uptime Kuma "API key": the API key you can create in the Uptime Kuma web UI is not a credential for this library. The UI "API key" cannot authenticate this socket.io API: it only grants access to Uptime Kuma's Prometheus /metrics endpoint. Authenticate with a username and password, or with a login token via login_by_token().

Now you can call one of the existing methods of the instance. For example create a new monitor:

>>> result = api.add_monitor(type=MonitorType.HTTP, name="Google", url="https://google.com")
>>> print(result)
{'msg': 'Added Successfully.', 'monitorID': 1}

At the end, the connection to the API must be disconnected so that the program does not block.

>>> api.disconnect()

With a context manager, the disconnect method is called automatically:

from uptime_kuma_api import UptimeKumaApi, MonitorType

with UptimeKumaApi('INSERT_URL') as api:
    api.login('INSERT_USERNAME', 'INSERT_PASSWORD')
    api.add_monitor(
        type=MonitorType.HTTP,
        name="Google",
        url="https://google.com"
    )

MonitorBuilder

For complex monitor configurations, use the fluent MonitorBuilder:

from uptime_kuma_api import UptimeKumaApi, MonitorType, MonitorBuilder

with UptimeKumaApi('INSERT_URL') as api:
    api.login('INSERT_USERNAME', 'INSERT_PASSWORD')
    
    config = (
        MonitorBuilder()
        .type(MonitorType.HTTP)
        .name("My Monitor")
        .url("https://example.com")
        .interval(60)
        .conditions([
            {"type": "expression", "variable": "response_status", "operator": "==", "value": "200", "andOr": ""}
        ])
        .build()
    )
    result = api.add_monitor(**config)
    print(result)

What this adds over the original library

• New monitor types: RabbitMQ, SNMP, SMTP, System Service
• New notification providers: Nextcloud Talk, Brevo, Evolution API
• MonitorBuilder: Fluent builder pattern for monitor configuration
• Logger support: Pass a custom logger for Socket.IO debugging
• v2-only parameters: Automatic version gating ensures backward compatibility with v1.x
• Fixes carried forward from the upstream tracker, plus defects found by this project's own live verification against real 1.x and 2.x servers

See CHANGELOG.md for the release-by-release detail — this list is deliberately not versioned, so it does not go stale one release at a time.

Testing

The v2 unit tests need no live server, and are what a bare pytest runs. This is also exactly what CI runs:

pip install pytest
pytest -v

The remaining test files are integration tests inherited from upstream. They expect a live Uptime Kuma instance at http://127.0.0.1:3001 and will delete all monitors, notifications, proxies, tags, status pages, docker hosts, maintenances and API keys on that instance, so never point them at a production server. They are excluded from a plain pytest run for that reason — opting in is explicit:

pytest -m integration     # DESTRUCTIVE: disposable instances only

The exclusion is not a list of filenames anyone maintains. tests/conftest.py marks a test integration when its class extends UptimeKumaTestCase, the base class whose setUp performs those deletions, and pytest.ini deselects that marker by default. So "needs a live server" is read off the code rather than restated, and adding a test file requires no change to CI, to the workflows, or to any command in this README.

The table below is coverage documentation, not a list anything executes — letting it fall behind degrades the docs, it cannot silently un-run a test.
