# Discovery

Retrieve active xToken metadata for integrators.

This endpoint returns the dynamic contract and asset data needed to integrate xTokens on a supported chain. Integrators can use it to discover xToken addresses, deposit pipe addresses, supported deposit assets, redemption pipes, and NAV oracle addresses without hardcoding them.

#### Endpoint

`GET /sdk/tokenized/xtokens`

#### Base URL

`https://api.liminal.money`

#### Query Parameters

| Parameter | Type   | Required | Description                                                     |
| --------- | ------ | -------- | --------------------------------------------------------------- |
| chainId   | number | No       | EVM chain ID to fetch xToken metadata for. Defaults to HyperEVM |

#### Example Request

```actionscript-3
curl "https://api.liminal.money/sdk/tokenized/xtokens?chainId=999"
```

| data\[].oftAddress                     | LayerZero OFT or OFT adapter address on the selected chain. May equal `address` when the xToken itself is the OFT. |

#### Notes

* data\[].address is the xToken address users receive after depositing.
* Each depositPipes\[] item maps one supported deposit asset to the DepositPipe that should be called for that asset.
* redemptionPipe is singular because each xToken has one redemption pipe for the selected chain.
* On Ethereum, Arbitrum, and other spoke chains, direct deposit/redemption pipe contracts do not exist; use the returned `oftAddress` for OFT-related integration.
