**Category:** Real Estate | **Website:** [huislijn.nl/](https://huislijn.nl/) | **Docs:** [parse.bot/marketplace/564284f2-f4c0-4a57-b113-272c0ec7aa60/huislijn-nl-api](https://parse.bot/marketplace/564284f2-f4c0-4a57-b113-272c0ec7aa60/huislijn-nl-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/huislijn/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get listing detail

Retrieve full details of a single property listing by its URL path. Returns the page title, structured feature groups (Algemeen, Woningdetails, Overige), description text, listing-agent info, and a list of similar nearby properties. The URL path is obtainable from search_for_sale_listings or get_newest_listings results.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `url` | string | Yes | Listing URL path starting with / (e.g. /koopwoning/nederland/zuid-holland/4379230/burgemeester-elsenlaan-323-f509-rijswijk). Obtainable from search_for_sale_listings or get_newest_listings results[*].link. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/huislijn/get-listing-detail \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"url":"<string>"}'
```

### Get newest listings

Retrieve the most recently added listings, filtered by listing type (sale or rent) and a days-lookback window. Returns the same listing-summary structure as the search endpoint. The total_results reflects how many listings matched the recency filter.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `days` | string | No | Days lookback as a negative integer string (e.g. '-3' for last 3 days, '-7' for last 7 days). |
| `type` | string | No | Listing type: 'sale' or 'rent'. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/huislijn/get-newest-listings \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"days":"<string>","type":"<string>"}'
```

### Search for sale listings

Search for homes for sale across the Netherlands. Supports price-range filtering and pagination. Each page returns up to ~15 listing summaries with structured property data (rooms, size, year built, energy label). The total_results count may be null when the site omits it.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | integer | No | Page number for pagination. |
| `price_from` | integer | No | Minimum price filter in EUR. |
| `price_to` | integer | No | Maximum price filter in EUR. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/huislijn/search-for-sale-listings \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"page":"<integer>","price_from":"<integer>","price_to":"<integer>"}'
```
