Example prompt:

Find roofing and solar permits issued in Denver and Aurora in the last 3 days with a project value over $10,000, and list the address, contractor and valuation for each.

Pricing

Pay only for what you get:

• $4 per 1,000 permits returned ($0.004 each)
• $0.005 per run

A daily run for one trade across all three cities typically costs a few cents.

How trade tagging works

Each permit's type, description and (where available) contractor name are matched against trade keywords. A permit can have several trades (e.g. a reroof plus a furnace swap); trade is the main one. Denver publishes a permit class rather than a free-text description, so Denver tags rely more on the contractor's name and are less precise.

Data quality guarantees

Every run checks that each city's feed has issued permits in the last 14 days and that key fields (permit number, address, issue date) are present. If a city's feed breaks, the run is marked as failed so it gets fixed, and permits from the healthy cities are still delivered.

Sources

All data is public and official:

• Denver: City and County of Denver Open Data (residential and commercial construction permits)
• Aurora: City of Aurora Open Data (building permits)
• Boulder: City of Boulder Open Data (construction permits)

Colorado Springs, Fort Collins and Lakewood don't currently publish a usable public permit feed. They'll be added if they do.

FAQ

Does it include contractor phone numbers or emails? No. The cities don't publish them.

Why is a permit missing? Cities sometimes publish permits a few days after issue. Re-run with a wider date range.
