# Bilbasen Metadata API Documentation

One cached call returns the category and make taxonomy, the self-describing search filters, and the Bilbasen sort orders. A cached serve makes no upstream lookup.

- **Documentation:** [https://scrappa.co/docs/bilbasen-api/bilbasen_metadata](https://scrappa.co/docs/bilbasen-api/bilbasen_metadata)
- **API group:** Bilbasen API
- **Endpoint:** `GET https://scrappa.co/api/bilbasen/metadata`

## Authentication

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" \
    "https://scrappa.co/api/bilbasen/metadata"
```
