# Asset Annotations

> Asset categorization — crypto, stocks, commodities

## Endpoint

```
GET /v2/perp-annotations
```

## Response

```json theme={null}
[
  ["flx:BTC", {"category": "crypto"}],
  ["flx:NVDA", {"category": "stocks"}],
  ["flx:GOLD", {"category": "commodities"}],
  ["flx:OIL", {"category": "commodities"}]
]
```

Array of `[coin, annotation]` pairs. Currently used by HIP-3 builder DEXes to classify their assets.

| Category      | Examples                               |
| ------------- | -------------------------------------- |
| `crypto`      | flx:BTC                                |
| `stocks`      | flx:NVDA, flx:COIN, flx:CRCL           |
| `commodities` | flx:GOLD, flx:OIL, flx:COPPER, flx:GAS |

The `flx:` prefix indicates Felix Exchange assets. Use alongside [`/v2/perp-categories`](/rest/discovery/perp-categories) for native HyperLiquid asset classification.

## Example

```bash theme={null}
