law4devs 1.0.0

Official Python SDK for the Law4Devs EU Regulatory Compliance API

law4devs

Official Python SDK for the Law4Devs EU Regulatory Compliance API.

Access structured, developer-friendly data for EU regulations — GDPR, Cyber Resilience Act, NIS2, AI Act, and more.

Installation

pip install law4devs

Python 3.9+ required. Zero runtime dependencies (stdlib urllib only).

Quick Start

from law4devs import Law4DevsClient

client = Law4DevsClient()

# List all frameworks
page = client.frameworks.list()
for fw in page:
    print(fw.slug, fw.name)

# Get framework detail
cra = client.frameworks.get("cra")
print(cra.name, cra.requirement_count)

# Fetch a specific article
article = client.articles.get("cra", 13)
print(article.title, article.content)

Authentication

The public API tier does not require authentication. Authenticated tiers provide higher rate limits:

client = Law4DevsClient(api_key="your-api-key")

Resources

Frameworks

page = client.frameworks.list(page=1, per_page=10)
print(page.meta.total, page.meta.pages)

cra = client.frameworks.get("cra")

for fw in client.frameworks.iter():
    print(fw.slug)

Articles

page = client.articles.list("cra", per_page=20)
art = client.articles.get("cra", 13)
related = client.articles.related("cra", 13)

for art in client.articles.iter("cra"):
    print(art.article_number, art.title)

Recitals

page = client.recitals.list("cra")
recital = client.recitals.get("cra", 10)

for recital in client.recitals.iter("cra"):
    print(recital.recital_number, recital.content[:80])

Requirements

page = client.requirements.list()
page = client.requirements.list(framework_slug="cra")

for req in client.requirements.iter(framework_slug="cra"):
    print(req.requirement_type, req.requirement_text[:60])

Compliance Deadlines

page = client.compliance.deadlines()
page = client.compliance.deadlines(framework_slug="nis2")

for d in client.compliance.iter_deadlines(framework_slug="nis2"):
    print(d.deadline_date, d.description)

Tags

page = client.tags.list()
tag = client.tags.get("security")

for tag in client.tags.iter():
    print(tag.slug, tag.name)

Annexes

page = client.annexes.list("cra")
annex = client.annexes.get("cra", "I")

for annex in client.annexes.iter("cra"):
    print(annex.annex_number, annex.title)

Search

results = client.search.query("vulnerability reporting")
results = client.search.query("audit", framework="gdpr")
results = client.search.query("encryption", result_type="requirement")

Auto-Pagination

All list resources support iter() which automatically fetches all pages:

all_articles = list(client.articles.iter("cra"))

for art in client.articles.iter("cra", per_page=50):
    process(art)

Error Handling

from law4devs import Law4DevsClient, NotFoundError, RateLimitError, Law4DevsError

client = Law4DevsClient()

try:
    fw = client.frameworks.get("nonexistent")
except NotFoundError as e:
    print(f"Not found: {e} (status {e.status_code})")
except RateLimitError:
    print("Rate limited — slow down requests")
except Law4DevsError as e:
    print(f"API error: {e}")
