# Otomoto Taxonomy API Documentation

Scrappa's `GET /api/otomoto/taxonomy` endpoint returns the Otomoto make/model taxonomy behind the search filters as JSON.

## What the response contains

`makes` lists every make with its live matching-ad `counter`. With `make_id`, `models` lists that make's models with their counters. `filters` carries the selectable values for fuel, transmission and body type.

## Frequently asked questions

### Do I need the taxonomy before searching?

No. The search endpoint validates make and model slugs itself. The taxonomy endpoint is for building pickers and validating input ahead of time.

### Are the counters live?

Yes. They are the matching-ad counts read from the embedded filter schema at request time.
