NYC Department of Buildings permit issuance — every construction, alteration, or demolition permit ever issued. Search by `bbl` (10-digit) or `address` (street_name substring). Filter by jobType (A1=Major Alteration, A2=Minor Alteration, A3=Minor Cosmetic, NB=New Building, DM=Demolition, etc.) or permitStatus (ISSUED, IN PROCESS, RE-ISSUED, REVOKED, etc.). Each row carries job + permit numbers, work type, building type, residential flag, filing/issuance/expiration dates, estimated fee. Use for construction-history agents, code-enforcement research, and zoning compliance checks.
/api/property/nyc-permitsPAYMENT-SIGNATURE.The nyc permits API is a pay-per-call property endpoint built for AI agents and autonomous software. NYC Department of Buildings permit issuance — every construction, alteration, or demolition permit ever issued.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in nyc permits data source for an agent tool-use loop, an MCP host, or a backend that needs property data on demand without onboarding to yet another vendor portal.
