NYC tax-lot lookup via PLUTO (Primary Land Use Tax Lot Output) — every tax lot in the city with owner, zoning, lot/building area, year built, classification, lat/lon, community + school + council + police districts. Pass `bbl` (10-digit Borough-Block-Lot composite, e.g. 1010110001 for the Empire State Building) for an exact lookup, OR pass `address` (partial-match) optionally constrained by `borough` (name or 2-letter code MN/BX/BK/QN/SI). The BBL returned here is the universal join key for all other property.nyc-* endpoints — fetch parcels first, then chain into deed-history, permits, or violations.
/api/property/nyc-parcel-lookupPAYMENT-SIGNATURE.The nyc parcel lookup API is a pay-per-call property endpoint built for AI agents and autonomous software. NYC tax-lot lookup via PLUTO (Primary Land Use Tax Lot Output) — every tax lot in the city with owner, zoning, lot/building area, year built, classification, lat/lon, community + school + council + police districts.
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 parcel lookup 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.
