Booli Property facts API

Read source-reported property and price facts from your account’s saved search or detail observation. Get structured JSON through one RealtyCrawl API key.

Get an API key View documentation

Use the listing_id from this account’s source search or detail response. Facts preserve the property and price fields actually collected; additional features depend on the source and observation. This read does not fetch missing fields or refresh the source. This detail beta uses primary page labels and synthetic offline fixtures, without fresh provider acceptance. It requires separate operator enablement. Exact country, market, property type and canonical URL must agree; unsupported pages fail without a search fallback. Booli source last bids, historical asking amounts and sold-or-removed dates remain distinct from normalized asking price and verified transactions. Total rooms are not bedrooms. This operation reads an account-owned retained observation. It does not refresh the source; inspect its collection time and retention limits. Check live capabilities for accepted inputs and availability before running your request.
