ipapp 4.0.0

A tiny ip.app client to query your IP, ASN, location & timezone using the 100% free IP.app API. Fast & reliable IP lookup.

ipapp • v4.0.0

Tiny stdlib-only client for ip.app. No dependencies on third party packages. Query your public IP address, ASN data, request headers, user-agent string, and more — programmatically or from the command line.

🛠 Installation

# From PyPI (after you publish)
pip install ipapp

# Local development / editable install (with test extras)
python -m pip install -e .[dev]

Python ≥ 3.8, no external runtime dependencies.

Using a virtual environment (recommended)

If your system Python is externally managed (PEP 668) you’ll need an isolated environment instead of installing into the OS packages. The fastest path is a virtual env:

python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install -e '.[dev]'

(Upgrade pip inside the venv if you like: python -m pip install --upgrade pip.)

Alternatively you can keep things completely separate with pipx:

pipx install --editable . --pip-args='.[dev]'

🚀 Quick-start (Python)

Each endpoint gets its own snippet so you can copy/paste exactly what you need.

Public IP

import ipapp
print(ipapp.get_ip())          # → "203.0.113.42"

Public IP via HEAD (fastest)

import ipapp
print(ipapp.get_ip(head=True))     # "203.0.113.42" via X-Ipapp-Ip header

ASN (plain-text)

import ipapp
print(ipapp.get_asn())         # → "AS12345"

ASN (JSON)

import ipapp
info = ipapp.get_asn(json=True)
# {'asn': 12345, 'holder': 'Example ISP', 'country': 'DE', ...}

ASN with caller IP merged (JSON only)

import ipapp
info = ipapp.get_asn(json=True, include_ip=True)
# {'asn': 12345, 'holder': 'Example ISP', ..., 'ip': '203.0.113.42', 'ip_version': '4'}

Timezone (plain-text)

import ipapp
print(ipapp.get_tz())          # → "Europe/Berlin"

Timezone (JSON)

import ipapp
info = ipapp.get_tz(json=True)
# {'tz': 'Europe/Berlin', ...}

Timezone with caller IP merged (JSON only)

import ipapp
info = ipapp.get_tz(json=True, include_ip=True)
# {'tz': 'Europe/Berlin', 'ip': '203.0.113.42', 'ip_version': '4'}

Location (JSON)

import ipapp
info = ipapp.get_location()    # JSON by default
# {'city': 'Berlin', 'country': 'DE', 'region': 'Berlin', ...}

Location with caller IP merged (JSON only)

import ipapp
info = ipapp.get_location(include_ip=True)
# {'city': 'Berlin', 'country': 'DE', ..., 'ip': '203.0.113.42', 'ip_version': '4'}

Location (plain-text)

import ipapp
print(ipapp.get_location(json=False))  # raw plain-text response

All helpers raise ipapp.IPAppError on network problems or invalid responses.

Strict mode

All functions support a strict=True parameter that raises IPAppError instead of returning None when the service responds with "Unknown":

import ipapp
try:
    ip = ipapp.get_ip(strict=True)
except ipapp.IPAppError:
    print("IP address is unknown")

---

🖥 Quick-start (CLI)

Every function is mirrored by a sub-command. No arguments prints the IP (nice for scripts):

ipapp                        # 198.51.100.7

Run each endpoint separately:

ipapp ip                     # same as default
ipapp ip --json              # {"ip": "198.51.100.7"}
ipapp ip --head              # header-only mode

ipapp asn                    # AS12345
ipapp asn --json             # {"asn": 12345, ...}
ipapp asn --json --include-ip # {"asn": 12345, ..., "ip": "198.51.100.7"}

ipapp tz                     # Europe/Berlin
ipapp tz --json              # {"tz": "Europe/Berlin", ...}
ipapp tz --json --include-ip # {"tz": "Europe/Berlin", "ip": "198.51.100.7"}

ipapp location               # {"city": "Berlin", "country": "DE", ...}
ipapp location --include-ip  # {"city": "Berlin", ..., "ip": "198.51.100.7"}
ipapp location --head        # header-only mode

🧪 Running the test suite

Tests are network-free (they monkey-patch the internal fetcher) so they run instantly:

pytest -q
# 4 passed in 0.02s

---

📦 Building & checking the package

# Ensure build tools are present
python -m pip install build twine

# Build wheel + sdist into ./dist/
python -m build

# Verify metadata is valid (no upload)
twine check dist/*

When you're ready to release, upload with Twine (or wire this into CI):

twine upload dist/*

🤝 Contributing

• Fork, create a feature branch, add tests for any new behaviour.
• Keep code PEP 8 compliant (the codebase sticks to stdlib only).
• Open a PR – CI will run pytest and basic metadata checks.
