# Lookup

Turn a human-readable option description into a well-formed OCC option symbol.

## Making Requests

Use the `lookup()` method on the `options` resource, built with `OptionsLookupRequest`.

```java
OptionsLookupResponse lookup(OptionsLookupRequest request)
CompletableFuture<OptionsLookupResponse> lookupAsync(OptionsLookupRequest request)
```

### OptionsLookupRequest

```java
OptionsLookupRequest.of(String userInput)
```

#### Returns

`OptionsLookupResponse` wrapping a `String` — the OCC option symbol. Read it with `.values()`.

## Examples

### Java

```java
import com.marketdata.sdk.MarketDataClient;
import com.marketdata.sdk.options.OptionsLookupRequest;

try (MarketDataClient client = new MarketDataClient()) {
  String occSymbol = client.options()
      .lookup(OptionsLookupRequest.of("AAPL 1/16/2026 $200 Call"))
      .values();
  System.out.println("Resolved to: " + occSymbol); // AAPL260116C00200000
}
```

### Kotlin

```kotlin
import com.marketdata.sdk.MarketDataClient
import com.marketdata.sdk.options.OptionsLookupRequest

MarketDataClient().use { client ->
    val occSymbol = client.options()
        .lookup(OptionsLookupRequest.of("AAPL 1/16/2026 \$200 Call"))
        .values()
    println("Resolved to: $occSymbol")
}
```
