InternetData Python Client Library

The official Python client library for the InternetData API.

The library helps you browse the databases your organization is licensed for, check what is in each build before you fetch it, and download and verify the files.

Getting Started

pip install internetdata

Requires Python 3.11 or newer. Type hints are included, and the package ships py.typed.

Usage

Every call needs an API key carrying the db.download scope. Create one in the console, then:

import os
from internetdata import InternetData

client = InternetData(os.environ["INTERNETDATA_API_KEY"])

for family in client.database.list():
    print(family.base, family.standing, [v.id for v in family.versions])

The client holds an HTTP connection pool, so use it as a context manager, or call client.close() when you are done with it:

with InternetData(api_key) as client:
    print(len(client.database.list()))

The catalog

list answers database FAMILIES. A licence is held against a family, while a download names a specific version, so the ids the other calls take come from each family's versions:

for family in client.database.list():
    if family.standing != "licensed":
        continue
    for version in family.versions:
        print(version.id, version.formats)   # 'bogon_ip_v1' ('csvgz', 'mmdb')

standing is licensed, expired or unlicensed, and license_type is what your licence lets you do with the data (evaluation, internal, redistribute, or None when there is no licence). A family you have never bought is still listed, as unlicensed, so you can see what else exists.

What is inside a build

metadata is cheap enough to poll. It answers when the build was generated, how many rows it has, its columns and a few real rows, and the size of each format in bytes, all without moving the file:

meta = client.database.metadata("bogon_ip_v1")

print(meta.updated)                  # datetime.date(2026, 9, 4)
print(meta.entries)                  # 1234
print(meta.size["csvgz"])            # 760
print([c.name for c in meta.schema["csvgz"]])

Checking size before a download is worth the round trip: the catalog spans a few hundred bytes to several gigabytes.

Downloading

Three ways, depending on what you want to do with the bytes:

url = client.database.download_url("bogon_ip_v1", "csvgz")
raw = client.database.download_bytes("bogon_ip_v1", "csvgz")
written = client.database.download("bogon_ip_v1", "mmdb", "./bogon_ip_v1.mmdb")

download_url hands back a time-limited link straight to object storage. It carries its own signature and none of your API key, so you can pass it to curl, a job runner or anything else that speaks HTTP. The link authorizes the START of a transfer, so one already running is not cut off when it lapses.

download streams to a file, so nothing larger than a chunk is ever held in memory. The bytes land in a neighboring .part file that is moved into place only once the whole transfer has arrived, so a failed refresh leaves the copy you already had untouched. download_bytes holds the whole file in memory, so reach for it only at the small end of the catalog.

Either way a short transfer fails rather than handing you a truncated file, and the key is never sent to object storage.

Verify what you fetched against the published digests:

import hashlib

digests = client.database.checksums("bogon_ip_v1", "csvgz")
assert hashlib.sha256(raw).hexdigest() == digests["sha256"]

Download history

downloads answers your organization's recent attempts, newest first, refusals included. A denial is what answers "it stopped working", and its absence answers nothing:

for attempt in client.database.downloads(limit=20):
    print(attempt.created, attempt.dataset_id, attempt.outcome, attempt.http_status)

Async

Everything above works the same way under asyncio, with AsyncInternetData:

import asyncio
from internetdata import AsyncInternetData

async def main():
    async with AsyncInternetData(api_key) as client:
        meta = await client.database.metadata("bogon_ip_v1")
        await client.database.download("bogon_ip_v1", "csvgz", "./bogon_ip_v1.csv.gz")
        print(meta.entries)

asyncio.run(main())

Errors

Failures raise an InternetDataError carrying a kind and a retryable flag:

from internetdata import InternetDataError

try:
    client.database.download_url("vpn_ip_v1", "mmdb")
except InternetDataError as err:
    print(err.kind, err.retryable, err.message)   # forbidden False NOT_LICENSED

kind is one of bad_request, unauthorized, forbidden, rate_limited, quota_exceeded, server_error or network. message is the API's own result code, passed through as it was sent, so you can switch on NOT_LICENSED against LICENSE_EXPIRED without reading the status.

Note that rate_limited and quota_exceeded both arrive as HTTP 429 and are not the same thing. A rate limit is the API facing a traffic burst, and retrying later works; a spent quota needs your allowance raised or the window to roll over. The library retries rate limits for you, and server and network failures, but never a spent quota or anything else you sent.

Other Libraries

There are official InternetData client libraries available for many languages including PHP, Python, Go, Java, Ruby, and many popular frameworks such as Django, Rails, and Laravel. See our GitHub at https://github.com/internetdata for more.
