# Open Interest Cap

> Assets currently at their open interest cap

## Endpoint

```
GET /v2/oi-cap
```

## Response

```json theme={null}
["CANTO", "FTM", "JELLY", "LOOM", "MAVIA", "RLB"]
```

Array of coin names that have hit their open interest cap. When an asset is capped:

* No new positions can be opened
* Resting orders cannot be placed more than 1% from oracle price
* HLP (protocol liquidity provider) is exempt and can continue quoting
* Existing positions can still be closed or reduced

This list changes as OI rises and falls. Typically contains illiquid assets with protective limits. HIP-3 builder-deployed markets have per-DEX OI caps set by the deployer (see [DEX Limits](/rest/discovery/perp-dex-limits)).

## Example

```bash theme={null}
curl -H "x-api-key: YOUR_KEY" https://hyper.polynode.dev/v2/oi-cap
```
