New This Week: Transportation Intelligence, SEC Financial Data & Health Learning Resources

What's New on Katzilla (Week of June 2, 2026)

This week we're excited to announce 10 new datasets now live in the Katzilla catalog, pulling from three major U.S. federal agencies. Whether you're building agents that analyze infrastructure safety, monitor financial markets, or support public health initiatives, these additions open up rich new possibilities.

🚆 Department of Transportation: A Deep Dive into U.S. Infrastructure

We've added seven datasets from the Department of Transportation, making Katzilla one of the most comprehensive single-access points for U.S. transportation data available to developers today.

• Grade Crossing Inventory System – Highway-Rail Grade Crossing Inventory (Form 71) Field Reference Table — Detailed field-level documentation for every highway-rail crossing in the national inventory. Essential for safety analysis and route planning agents.
• Vehicle Miles of Travel by Federal-Aid Highways, 2000–2024 (VM-3) — Annual VMT figures broken down by Federal-Aid highway designation, covering 24 years of trend data.
• Vehicle Miles of Travel by Functional System and State, 1980–2024 (VM-2) — A longer-horizon companion dataset spanning over four decades of state-level travel patterns.
• Investigations Data — Records of DOT-led safety investigations, useful for compliance monitoring and risk-assessment workflows.
• Inspections and Citations — Enforcement actions and inspection outcomes across transportation entities.
• State, County and City FIPS Reference Table — A clean geographic lookup table for joining datasets by FIPS code — a quiet workhorse for any geospatial pipeline.
• Railroad Master — A master reference list of railroads operating within the U.S., including identifiers and classification metadata.

📈 SEC: Investment Company & Business Development Data

Two new datasets from the Securities and Exchange Commission are now available:

• Investment Company Series and Class Information — Structured data on registered investment company series and share classes, enabling fund research and compliance tools.
• Business Development Company Report — BDC-specific filings data, critical for agents tracking alternative lending and private credit markets.

🏥 HHS: Learning Resources Database

From the U.S. Department of Health & Human Services, the Learning Resources Database catalogs educational and training materials across public health programs — a valuable asset for agents supporting health literacy, workforce development, or policy research.

Query It Now with the Katzilla SDK

All ten datasets are available immediately. Here's how to pull railroad master data and VMT trends in a single session:

from katzilla import Katzilla

client = Katzilla(api_key="your_api_key")

# Fetch Railroad Master records
railroads = client.datasets.query(
    dataset_id="dot.railroad-master",
    limit=50
)

# Fetch Vehicle Miles of Travel by State (VM-2)
vmt_by_state = client.datasets.query(
    dataset_id="dot.vm2-vmt-functional-system-state",
    filters={"year": 2024},
    limit=100
)

for record in vmt_by_state.results:
    print(f"{record['state_name']}: {record['total_vmt_millions']}M miles")
