Off-market lead generators

An off-market lead generator is a saved, area-based scanner (outcodes or a drawn polygon) that surfaces properties not currently listed for sale but showing seller-motivation signals: long ownership duration, equity gained since last sale, high motivation score, serial-investor ownership, or negative equity. Each matched property carries a lead classification — hot, warm, standard, or low — plus enrichment badges for company-owned, distressed-company, and silently-pulled (recently delisted) properties. The workflow is: create a lead generator over your target area, then query its /properties endpoint with filters and sorting to pull ranked leads. The /counts endpoint gives the classification breakdown for the area. Required scope: leads:read Cost: 1 request per call Available on: Starter, Professional, Business

The number of lead generators you can hold at once is capped by your plan. Creating one beyond the cap returns 403 — delete an existing generator first. Each generator is tied to the account that created it.

List your lead generators

GET /api/v1/off-market-lead-generators

Returns all active off-market lead generators for the authenticated account, plus your plan limit and remaining headroom.

The company-ownership and silent-pull fields are best-effort enrichments — they are only present on rows where a match was found. Under heavy load the search degrades gracefully: you may receive an empty page with "degraded": true rather than an error; retry shortly.

Get classification counts

GET /api/v1/off-market-lead-generators/{lg_id}/counts

Returns the property count breakdown by lead classification for the generator’s area — useful for sizing an area before pulling pages of leads.

Request

curl https://api.propaideals.co.uk/api/v1/off-market-lead-generators/8c1f6a2e-3b4d-4e5f-9a0b-1c2d3e4f5a6b/counts \

    headers={"Authorization": f"Bearer {API_KEY}"},
)
counts = res.json()
print(f"HOT leads: {counts['hot']}")

Param	Type	Required	Description
`lg_id`	UUID (path)	Yes	The lead generator ID

Response

{
  "hot": 18,
  "warm": 64,
  "standard": 211,
  "low": 95
}

Update or delete a lead generator

PUT /api/v1/off-market-lead-generators/{lg_id}
DELETE /api/v1/off-market-lead-generators/{lg_id}

PUT accepts the same fields as create — all optional, only provided fields are changed (a body with no fields returns 400). DELETE soft-deletes the generator (returns 204 No Content) and frees a slot against your plan cap.

Request

curl -X PUT https://api.propaideals.co.uk/api/v1/off-market-lead-generators/8c1f6a2e-3b4d-4e5f-9a0b-1c2d3e4f5a6b \
  -H "Authorization: Bearer paid_..." \
  -H "Content-Type: application/json" \
  -d '{"search_criteria": {"min_yield": 7.0}}'

import requests

requests.delete(
    f"https://api.propaideals.co.uk/api/v1/off-market-lead-generators/{lg_id}",
    headers={"Authorization": f"Bearer {API_KEY}"},
)

Response

PUT returns the updated lead generator object (same shape as create). DELETE returns 204 with no body.

Use cases

Direct-to-vendor sourcing — Pull hot leads with long ownership and high equity, then run letter or door-knock campaigns
BTL deal origination — Filter by min_yield to find off-market stock that pencils as a rental before it ever lists
Company-owned targeting — Surface is_company_owned / is_distressed_company titles for portfolio acquisition approaches
Failed-listing follow-up — silent_pull_tier flags properties recently withdrawn without selling — motivated vendors with a known asking-price anchor

Lead generators — On-market scanners over live listings with the same saved-search model
Properties — Search and retrieve live on-market property records
