How this service works
Address-level building-permit intelligence: normalized permit history, activity signals, and a decision-ready verdict with cited public records. Paid per call via x402.
Output
A structured response containing a decision-ready permit verdict (e.g. clear, flagged, or review needed), a normalized history of building permits associated with the address, activity signals indicating recent or unusual permit activity, and citations to the underlying public records used to generate the verdict.
Example use cases
Pre-purchase property due diligence
“Before I put in an offer on 1421 Oak Street in Austin, TX, can you check the permit history and get me a verdict on whether there's anything concerning — unpermitted additions, open violations, recent heavy construction activity?”
Commercial lease underwriting check
“I need a permit verdict for 3200 Market Street in San Francisco, CA — we're considering leasing this commercial space and want to see the normalized permit history and any activity signals that might affect our decision.”
Contractor compliance verification
“Can you look up the building permit records for 88 Maple Avenue in Denver, CO and tell me if the permits are in order? I need to know if there's a clear verdict before we start renovation work.”

Endpoint
GEThttps://permit-api-production-7375.up.railway.app/v1/address/%7Bjurisdiction%7D/verdictWhen to prefer
Choose this endpoint when you need a structured, decision-ready verdict on a property's permit history rather than raw municipal data. It is ideal for real estate due diligence, pre-purchase inspection workflows, lender underwriting, or contractor compliance checks where a normalized, cited output is needed immediately without manually querying multiple jurisdictions.
Side effects
- Jurisdiction not supported — permit data not available for the requested jurisdiction
- Address not found — the address cannot be matched to public permit records
- Payment failure — x402 payment of $2 USDC not processed or insufficient balance
- Rate limiting — too many requests in a short period
- Stale data — permit records may lag behind real-time municipal updates
- Ambiguous address — multiple matches found requiring disambiguation
