# Fincaraiz Available Filters API Documentation

Scrappa's `GET /api/fincaraiz/available-filters` returns the platform's own filter catalogue, so you can build a filter UI from the same vocabulary the search endpoint accepts.

Each entry is a named filter group — price, bedrooms, bathrooms, stratum, surface range, garage, sea distance, and more — with its own definition and options. `returned` is the number of groups.

This describes what the platform offers, not what each filter is called on the search endpoint. Search parameter names are documented on the search page; unsupported names are rejected there rather than silently ignored.

Send your Scrappa API key in the `X-API-KEY` request header. Paid endpoints also support accountless x402 payments when called without an API key.

## Example request

```bash
#!/bin/bash

curl -X GET \
    -H "x-api-key: YOUR_API_KEY_HERE" \

## Errors

| Status | Error | Description |
| --- | --- | --- |
| 503 | Unreadable Response | The platform answered successfully with a body this endpoint cannot read, so nothing is published and nothing is charged (`parser_drift`). Retryable. |
| 503 | Upstream Unavailable | The upstream request failed after retries. Retryable and never billed. |

## Frequently asked questions

### Are these the same names the search endpoint takes?

No. This is the catalogue of filters the platform offers. Search uses its own parameter names, documented on the search page — a name sent to search that the platform ignores is rejected rather than silently dropped.
