Particle Space Property Records API

openapi: 3.0.1
info:
  title: Particle Space Address Search Property Records API
  description: 'Particle Space is proptech infrastructure for real-estate and property data. The API is organized around REST, has resource-oriented URLs, accepts form-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs. Requests are authenticated with an API key; the key determines whether the request runs in live mode or test mode.

    This specification models the documented Particle Space data-platform product areas - property records, address/property search, valuations (AVM), comparables, and listings (for sale, rent, and off-market). The exact request paths, query parameters, and response schemas should be reconciled against the live API reference at https://docs.particlespace.com/docs/intro/. Resource paths and field names below are illustrative of the documented product areas and are marked unreconciled until verified.'
