PlanNexus

• Search Applications — Search UK planning applications across ~363 local planning authorities. Combine any of: - query: free text matched against description + address - postcode: full or partial UK postcode (prefix match, e.g. "SW1A" or "SW1A 1AA") - authority_id: a council UUID — use find_authority to look one up by name - lat + lng + radius_m: everything within radius_m metres of a point - application_type: e.g. "householder", "full", "outline", "listed_building" - status: e.g. "approve
• Get Application — Full detail for one planning application by id. Returns address, description, type, status, decision, all dates, ward/parish, coordinates, EPC (where matched) and — on a paid PlanNexus plan — the applicant, agent and case-officer contact details (redacted on the free tier, with a ``redacted_fields`` list). Get the id from search_applications.
• Get Constraints — Planning constraints at a point — by UK postcode, or by lat + lng. Returns which designations apply at that location: conservation area, listed building, Article 4 direction, tree preservation order (TPO), flood risk zone, green belt, scheduled monument, AONB, SSSI, world heritage site, and more. Answers "what would affect a development at this address?".
• Find Authority — Find UK local planning authorities (councils) and their ids. Pass a name or partial name (e.g. "camden", "north lincolnshire") to filter, or omit to list all active councils. Use the returned id as ``authority_id`` in search_applications to scope a search to one council.
