How it feels.

Two columns, one round trip.

01

You ask.

curl https://api.zillapi.com/v1/properties/by-address \
  -H "Authorization: Bearer zk_..." \
  --data-urlencode \
    "address=3624 Bohlke Blvd, Cincinnati, OH" -G

Or pass a Zillow URL. Or a zpid. Or a street address. The API geocodes for you.

02

We return.

Built for the people building real estate software.

A

Real estate apps

Power Zillow-grade listing pages without scraping anything yourself. Agent CRMs, brokerage sites, off-market platforms.

B

AI agents

Drop the OpenAPI spec into Claude or ChatGPT. Now your assistant answers "what would 18 Zelma sell for today?" with real numbers.

C

Market analysis

Pull thousands of properties async, get the results back via signed webhook. Stream straight to BigQuery or Snowflake as NDJSON.

D

Lead enrichment

Convert street addresses sitting in your CRM into full property profiles. Owner names, year built, last sale, school zone.

Pricing that scales like your bill.

Every plan includes the full API. You only pay for the rows you read.
