Field projection

The detail response has 300+ fields. If you only want a few, project them:

GET /v1/properties/11026031?fields=zpid,address.streetAddress,price,zestimate
{
  "data": {
    "zpid": "11026031",
    "address": { "streetAddress": "17 Zelma Dr" },
    "price": 295000,
    "zestimate": 305100
  },
  "cached": true,
  "request_id": "..."
}

Syntax

  • Top-level field: price
  • Nested via dot: address.streetAddress
  • Array index via [n]: priceHistory[0].price
  • Whole array: priceHistory (returns the full array)

Where it’s available

EndpointNotes
/v1/properties/by-urlSingle object
/v1/properties/by-addressSingle object
/v1/properties/{zpid}Single object

Sub-resources (e.g. /photos, /schools) are already field-scoped, so ?fields= is unnecessary there.

Unknown fields

Fields that don’t exist in the response are silently dropped — they don’t cause an error. Always test with the field you expect against a known zpid first.
