Lead generators

Lead generators are saved investment scanners: an area (a set of outcodes or a drawn polygon) plus filter criteria (price, beds, yield, BMV, 60+ keyword flags such as probate or needs_modernisation), persisted server-side and queryable on demand. They run against 2.1M+ live UK listings refreshed daily, so the same scanner returns new deals each time you poll it. Typical integration: create a scanner once, then page through /{lg_id}/properties (or pull the CSV export) on a schedule. Required scope: leads:read Cost: 1 request per call Available on: Starter, Professional, Business

Scanner endpoints are plan-gated on the underlying account: the number of scanners you can hold is limited by subscription tier, and a free-tier account returns 403. Requests over a paid_* API key are authorised as the key owner’s account.

List lead generators

Returns all active lead generators for the authenticated account, with plan limit and remaining headroom.

Preview match counts

Fast COUNT preview for a scanner-in-the-making — see the rough size of the result set for a given area + criteria before saving. Where the chosen playbook has stored tiers, a gold/silver/bronze breakdown is included. Soft-fails (never errors): a failed count returns status: "timeout" with total: 0.

POST /api/v1/lead-generators/preview

Request

curl -X POST https://api.propaideals.co.uk/api/v1/lead-generators/preview \
  -H "Authorization: Bearer paid_..." \
  -H "Content-Type: application/json" \
  -d '{
    "selected_outcodes": ["LS1", "LS2", "LS6"],
    "search_criteria": {"max_price": 150000, "min_yield": 7}
  }'

import requests

res = requests.post(
    "https://api.propaideals.co.uk/api/v1/lead-generators/preview",
    headers={"Authorization": f"Bearer {API_KEY}"},
    json={

    },
)
preview = res.json()
print(f"{preview['total']} matches ({preview['area_total']} in area before filters)")

Param	Type	Required	Description
`selected_outcodes`	string[]	No*	Outcode strings, e.g. `["EH1", "EH2"]` (uppercased automatically)
`polygon_wkt`	string	No*	WKT geometry for a custom drawn area
`search_criteria`	object	No	Filter criteria, same shape as the create endpoint

*At least one of selected_outcodes or polygon_wkt should be set — with neither, the endpoint returns an empty preview (status: "empty") without querying.

Response

  "has_tier_data": true,
  "status": "ok"
}

Field	Type	Description
`total`	integer	Properties matching area + all criteria
`area_total`	integer	Properties in the area before your criteria — if `total` is 0 but this is non-zero, your filters are too strict
`tier_breakdown`	object \| null	Gold/silver/bronze counts when the chosen playbook has stored tiers; null otherwise
`playbook`	string \| null	The playbook slug, if one was set in criteria
`has_tier_data`	boolean	True when `tier_breakdown` is populated
`status`	string	`ok` (honest count) / `capped` (`total` is a soft cap, real value higher) / `timeout` (count took too long — narrow the search) / `empty` (no area selected)

Create a lead generator

Persists a new scanner. Either selected_outcodes or polygon_wkt must be provided. Plan-based scanner count limits apply — exceeding them returns 403.

Export properties as CSV

Streams a CSV of properties matching the scanner. Accepts the same filter / sort_by / status query params as /{lg_id}/properties. Capped at 10,000 rows, Excel-compatible (UTF-8 with BOM). The X-Export-Row-Count response header carries the row count.
