# Willhaben Listing Details API Documentation

<p>Scrappa's `GET /api/willhaben/details` endpoint is the Willhaben Details API documentation page for developers who need a single Austrian listing as structured JSON instead of parsing listing pages.

    ## What this endpoint returns

    Scrappa returns the complete listing record: the full date lifecycle, all listing attributes, every image URL, the address and location context, category information, and the advertiser's business contact details. Private-seller contact details are never included.

    ## How to use it

    Use [Willhaben Search](/docs/willhaben-api/willhaben_search) to find a listing id, then pass that id here to expand a search card into a full listing record. Use [Agency Profile](/docs/willhaben-api/willhaben_agency) to resolve the advertiser behind the listing.</p>

## Errors

| Status | Error | Description |
| --- | --- | --- |
| 404 | Not Found | The requested listing, agency or seller does not exist upstream. Non-billable, and not retryable: a different exit returns the same 404. |
| 422 | Validation Error | A query parameter failed validation — a missing required id, an unknown vertical, or a value outside the documented range. Messages are per field in Laravel's standard wording, so the accepted vertical ids are published on the `vertical` parameter of each page rather than repeated in the message. Non-billable. |
| 503 | Upstream Rejected The Request | Willhaben answered with a JSON application error — an invalid filter, or a sort id that the vertical does not offer. Non-billable, and not retryable: the same request fails the same way on every exit. Published as 503 because SanitizeApiErrorResponse rewrites every upstream 502 before the response leaves the app; branch on `meta.retryable` rather than on the status code. |
| 503 | Temporarily Unavailable | Willhaben could not be reached at all: no exit was available, the transport failed, the edge refused every exit, or every exit was rate limited. All of these rotate and retry, so this row is always retryable. The `failure_type` says which one happened — `upstream_unreachable`, `transport_error`, `edge_blocked`, `rate_limited` or `attempts_exhausted` — so a caller can tell a dead provider from a throttled one. Non-billable; a later request with a fresh pool fetch is worth making. |
