Propdata

propdata

Zillow property data through the APIllow API: search homes by city or ZIP code, pull a single property by its Zillow ID, its listing URL or its street address, look up several addresses in one call, check which addresses currently have an active listing, create a free account, and see how much of the monthly quota is left.

Property answers come from the upstream service and are passed through untouched, so a property record carries what APIllow returns for it — identifiers, address, status and type, bed and bath counts, living area and lot size, year built, pricing and estimates, sale and tax history, a small set of comparable homes, photos, and nearby schools.

Nine tools are provided. A tenth tool in the upstream catalogue, a plan-upgrade helper whose only output is a payment link, is deliberately not part of this package.

The nine tools:

• search_properties — search by city or area, with an optional listing type and a cap on how many results come back.
• search_by_zip — search by one or more ZIP codes.
• get_property — one property by its Zillow property ID.
• get_property_by_url — one property from its Zillow listing URL.
• get_property_by_address — one property by street address.
• get_properties_by_addresses — several street addresses looked up in a single request.
• check_addresses — which of a set of addresses has an active Zillow listing, with the listing URL.
• signup — create a free account; the API key arrives by email after verification.
• check_usage — current usage, quota and plan details.

Configuration

export APILLOW_API_KEY="..."   # required for every tool except signupexport APILLOW_BASE_URL="https://apillow.co/api"   # optional override

Without a key, every tool except signup fails with APILLOW_API_KEY is not set, before any argument checking. The key is sent to the API as an X-API-Key header.

CLI

Each tool is a subcommand taking one JSON argument string:

npx @reneturcios/propdata search_properties '{"query":"Austin TX","type":"sale","max_items":10}'npx @reneturcios/propdata search_by_zip '{"zip_codes":[90210]}'npx @reneturcios/propdata get_property '{"zpid":12345678}'npx @reneturcios/propdata check_usage '{}'npx @reneturcios/propdata --version

Output is the upstream JSON, printed unchanged. Exit codes: 0 on success, 1 on a runtime error (including a validation or upstream failure), 2 on a usage error.

MCP server

npx -y @reneturcios/propdata mcp

MCP client config:

{  "mcpServers": {    "propdata": {      "command": "npx",      "args": ["-y", "@reneturcios/propdata", "mcp"],      "env": {        "APILLOW_API_KEY": "..."      }    }  }}

Docker

docker run -i -e APILLOW_API_KEY="..." ghcr.io/cloudcorprecords/propdatadocker run --rm -e APILLOW_API_KEY="..." ghcr.io/cloudcorprecords/propdata check_usage '{}'

Development

npm installnpm run build   # tsc -> dist/npm test        # tsx --test test/*.test.ts (fake fetch, no network)npm run dev     # run the CLI from source
