# Bridge API

> Learn how to use the SDK to interact with the bridge API directly.

## Introduction

You can use the bridge API directly if you need some additional data or if your application requires more control over the bridge flow. For that the SDK offers a typesafe wrapper around the Rhino API through a dedicated object. The following sections showcase some common use cases for this.

## Fetch bridge or token configs

```typescript theme={null}
const bridgeConfigResult = await rhinoSdk.api.bridge.getBridgeConfig()
const tokenConfigResult = await rhinoSdk.api.bridge.getTokenConfig({
  chain: 'ETHEREUM',
  token: 'USDT'
})
```

## Generate and commit bridge quotes

```typescript theme={null}
const publicQuoteResult = await rhinoSdk.api.bridge.getPublicQuote({
  token: SupportedTokens.USDT,
  chainIn: SupportedChains.ETHEREUM,
  chainOut: SupportedChains.SOLANA,
  amount: '100',
  mode: 'pay',
})

const userQuoteResult = await rhinoSdk.api.bridge.getUserQuote({
  /// Same args as public quote with additional depositor and recipient address added
})
if(userQuoteResult.error) {
  throw new Error(`Error fetching user quote: ${userQuoteResult.error}`)
}
const quoteId = userQuoteResult.data.quoteId

const commitmentResult = await rhinoSdk.api.bridge.commitQuote(quoteId)
if(commitmentResult.error) {
  throw new Error(`Error committing quote: ${commitmentResult.error}`)
}
```

<Note>
  The [bridge functions](/sdk/bridge-functions/bridge) in the SDK will already handle this logic for you. You should only do this manually if you have a very specific use case that is not covered by those.
</Note>

## Fetch bridge status or history

If you want to check the status of a bridge or fetch the history of your app, you can use the following functions:

```typescript theme={null}
const statusResult = await rhinoSdk.api.bridge.getBridgeStatus(quoteId)
const historyResult = await rhinoSdk.api.bridge.getUserBridgeHistory({page: 1, limit: 10 })
```

<Warning>
  Querying the bridge history is only possible with a secret API key. [Learn more about API keys](/get-started/api-keys)
