# Fincaraiz Fast Search API Documentation

Scrappa's `GET /api/fincaraiz/fast-search` is a lightweight id lookup: it returns identifiers for a page of listings without the full search payload.

Use it to power a type-ahead that only needs ids — an autosuggest list, or resolving which listings a user picked before fetching detail. Each result carries `id`, `legacy_propID`, and `isProject`.

It accepts no filters beyond the transaction type, and it returns no `total`. When you need filtering or an exact count, use the search endpoint.

## Frequently asked questions

### When should I use this instead of search?

When you only need identifiers, such as powering a type-ahead. Use search when you need filters, listing data, or an exact count — this endpoint returns no total.
