## GET /api/v1/categories

Get product categories

- Operation ID: `categories`
- Slug: `categories`
- Category: Categories
- Authentication: API key only. Reads public marketplace data, so no store needs to be connected.
- HTML: https://eto.tools/dev/docs/#ep-categories
- Markdown: https://eto.tools/dev/docs/categories/categories.md

Get the full product category tree (e.g. Jewelry, Clothing, Home Decor). Use category IDs when creating listings to place them in the right section. Etsy docs: "Seller Taxonomy Nodes".

Proxied to the Etsy API at `/v3/application/seller-taxonomy/nodes`. Fields Etsy returns are passed through untouched.

### Parameters

None. Send the request with only the API key header.

### Request

```bash
curl -H "X-Eto-API-Key: eto_your_key" "https://eto.tools/api/v1/categories"
```

```python
import requests

url = "https://eto.tools/api/v1/categories"
headers = {"X-Eto-API-Key": "eto_your_key"}

response = requests.get(url, headers=headers, timeout=120)
response.raise_for_status()
print(response.json())
```

```javascript
const url = "https://eto.tools/api/v1/categories";

const response = await fetch(url, {
  method: "GET",
  headers: {
    "X-Eto-API-Key": "eto_your_key",
  },
});
if (!response.ok) throw new Error(`Eto API ${response.status}`);
const data = await response.json();
```

### Response

`application/json`, passed through from Etsy’s `/v3/application/seller-taxonomy/nodes` verbatim. The field-by-field data model is in the [v2 preview reference](https://eto.tools/eto-dev-api-v2/), which documents these same routes alongside the whole Etsy schema.

### Errors

Failures answer with the shared error body described in the Errors section: `{"error": {"code", "status", "message", "hint", "docs"}}`. Branch on `code`, not on the message.
