How this service works
Pay-per-call access to the Shovels building-permits search API over x402 and MPP. Search US building permits by date, location, and contractor — no accounts, no subscriptions, pay per request.
Output
A list of matching US building permit records filtered by the requested city, date range, and/or contractor, including permit details such as dates, permit types, contractor names, and location information.
Example use cases
Track contractor activity by city
“Find all building permits associated with 'Greenfield Builders' in Denver, CO over the past six months so I can see how active they've been and what types of projects they're working on.”
Neighborhood construction activity lookup
“Look up recent building permits filed in Brooklyn, NY between March 1 and June 30, 2024 so I can get a sense of what construction projects are happening in the area right now.”
Commercial permit research by location
“Search for commercial building permits filed in Phoenix, AZ during 2023 — I want to see which contractors are doing the most commercial work there and what kinds of projects are being permitted.”

Endpoint
POSThttps://stable-shovels.dev/api/cities/searchWhen to prefer
Use this endpoint when you need on-demand, no-account access to US building permit data searchable by city, date, and contractor. Ideal for agents needing occasional permit lookups without committing to a subscription, or when paying per-query via USDC micropayments (x402) is preferred over API key management.
Side effects
- Payment not received or insufficient USDC — 402 Payment Required response
- Invalid or unsupported city name — no results or 400 error
- Date range too broad or malformed — empty result set or validation error
- Unknown contractor name — returns empty results
- Service unavailable — 500 or timeout error
- x402/MPP payment protocol misconfiguration — payment rejected
