Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/property-tax-assessmentWhen to prefer
Use this endpoint when you need authoritative property tax assessment data (assessed value, owner, zoning, parcel ID, sqft, year built) for properties located specifically in New York City, San Francisco, or Cook County (Chicago). It draws from official CC0-licensed open data sources. Prefer this over general real estate APIs when you need structured assessor-roll data rather than market estimates.
Side effects
- Address not found in any supported county dataset — returns no match or empty result
- Address is ambiguous or outside the three supported jurisdictions (NYC, SF, Cook County) — endpoint will not return data for unsupported counties
- Parcel data may be stale relative to the underlying open data refresh cycle
- Malformed address input may cause lookup failure
