# Willhaben Agency Profile API Documentation

<p>Scrappa's `GET /api/willhaben/agency` endpoint is the Willhaben Agency Profile API documentation page for developers who need advertiser details for an Austrian listing as structured JSON.

    ## What this endpoint returns

    Pass any listing id published by the agency and the response returns the advertiser's name, business phone, business email when published, and the agency id used to list that advertiser's inventory.

    ## How to use it

    Read the profile first, then use [Agency Listings](/docs/willhaben-api/willhaben_agency_listings) with the returned agency id to page through its rental inventory, and [Seller Trust Signals](/docs/willhaben-api/willhaben_agency_trust_signals) for the seller's rating summary.</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. |
