API key100 tokens a call13 parameters

Send Authorization: Bearer $CASAFARI_API_KEY: a platform API key (cf_sk_...) from the console, or an OAuth access token; X-API-Key carries the key too. See platform API keys. Costs 100 tokens a call (1 token = EUR 0.04).

The platform's OpenAPI file leaves the shape open; what is shown comes from the same definitions the platform publishes elsewhere: response 200: the hub's fragment from the platform's contract.

Over MCP: none; this product is REST only.

Description

Costs 100 tokens a call. Each page is a call. One search reaches at most 1000 results. Each lead is {id, property_id, coordinates, price_cuts, price_cuts_since}: the property id, its coordinates and its price reductions, no property details (type, price, size, address). For a lead's details, pass its property_id to Property Sourcing's GET /v1/property-sourcing/properties/{property_id} (10 tokens).
